Subaru Cooling System Repair Centre

Your cooling system plays a critical role in your vehicle’s performance and efficiency. Internal combustion engines are designed to run at maximum efficiency within a narrow temperature range. Outside this range, and engine will use more fuel, or run poorly, and overall engine reliability and longevity will be reduced. If your cooling system fails altogether, the engine will overheat, which could cause head gasket failure, and damage to bearings and pistons. The cooling system is vital.

Your Subaru engine is kept at the correct operating temperature by liquid coolant pumped through internal galleries in the engine block and heads. Heat from the internal combustion process is transferred from the engine to the coolant. The coolant then passes through a radiator which transfers the engine heat into ambient air passing through the core. The system is efficient enough so that even with ambient temperatures past 50 Celsius, the engine will still run too cool if the flow of coolant is not regulated, which is done by two parts of the cooling system: the thermostat, and the electric cooling fan controlled by a thermostatic switch.

When engine temperature gets too low, the thermostatic switch cuts power to the fan, and the thermostat closes off the flow of coolant from the radiator to the engine. As the engine gets hotter, the thermostat valve opens to allow hot coolant to flow though the radiator and the thermostatic switch turns on the fan to increase the flow of air through the core. This system keeps the temperature so constant that the driver will not see the temperature gauge move, once the engine has reach operating temperature.

At All Drive Subaroo we are aware of the importance of keeping your car cool under the bonnet, and we routinely check for leaks or other problems with your head gasket, hoses or radiator., Most of the time any fixes required are easy and simple but some are more complex. We recommend regular inspections for leaks around the Subaru heads.

All Drive Subaroo are Subaru cooling systems experts. When it comes to your radiator,or any other part of your car’s cooling system, we are the people to see.

Difficulty of Subaru engine overheating diagnosis

Given the complexity of the cooling system, problems with maintaining correct engine temperature or with retaining coolant, might have a number of causes and diagnosis can be tricky. Many customers have come to us with what they think is a head gasket problem, and are greatly relieved when it proves to be a problem with other parts of the cooling system. When you bring your car to All Drive Subaroo, our technicians thoroughly inspect the engine compartment and cooling system to determine what work or service is required. Checks that we are able to perform include:

  • Power vacuum bleed of system
  • TK check
  • Engine compression test
  • Cooling system pressure test
  • Fluid dye test
  • Cylinder speed test
  • Electrical diagnosis using Subaru SSM machine

One very common problem occurs when cooling systems are fully drained and then refilled, either as part of a routine service replacement of coolant, or following cooling system or head gasket repairs where the coolant is drained. Modern Subarus cannot simply be filled up with coolant from the header tank or directly into the radiator. If this is done there will be large pockets of air left in the system, and the engine will overheat. There is no bleed nipple on Subaru engines to ensure that all air is out of the system, and the only way to do this properly is by use of a special coolant vacuum purge and refill kit that sucks air out at one end, while drawing coolant in at the other. Not all workshops have this equipment available, but as a specialist Subaru service center, ADS does, as well as all other specialist tools and equipment required to service Subaru cars. Whatever the problem is, we can most likely fix it for you on the spot.


Genuine Subaru Radiators vs cheap knock-offs

A few decades ago, car radiators were made from brass and copper, highly durable materials, and easy to repair. There used to be a thriving business in reconditioned radiators, and radiator repairs such as re-braised or soldered tanks, and flushed and cleaned cores. Modern cars however use much thinner aluminium cores and plastic tanks. When these fail, they often cannot be repaired. This has created a new market for replacement radiators, and after-market manufacturers, notably Chinese companies, have been quick to jump in. The Chinese built after-market replacements are less than half the price, but they are virtually non-serviceable. They are a copy of the OEM Subaru design, but the build quality is inconsistent. We have tried to install units supplied by customers, only to find that the mounting points do not precisely align, or the unit is slightly too wide for the mounting frame, requiring a little distortion to fit. We have observed that these radiators inevitably fail after only a short time, and in demanding conditions, simply fail to keep the engine cool. This is because they use less metal—one or two rows of honeycomb cooling cells instead of three, as in the OEM Subaru units, and high quality Japanese made after-market units. The Chinese units also use inferior seals to hold the top and bottom tanks on, and generally thinner gauge materials all round. The result, all too often, is overheating and an expensive engine repair that could have been avoided. OEM Subaru radiators, and other quality units built in Japan, are not cheap, but they are of very high quality. We keep a large stock of OEM Subaru radiators, and high quality Japanese built after market units in stock, and we are very aware of the importance of making sure your car engine stays cool and in optimum condition. Ensuring your car engine runs at the correct temperature, may involve a radiator fluid exchange, a simple part replacement or more complex repairs.

    These specialists know their cars and they know Subaru...very well. The staff are competent, courteous and a delight to do business with. I recommend them unreservedly!

    I don't write negative reviews thus I am not a keyboard warrior; this is my first.

    Acted in an unprofessional manner, was quoted one price and then would not honor that pricing. The error was made on their side as all the information they required and have I the documentation to prove it. The person who I spoke with either ignored this or could not grasp the emails and documented timeline provided. Deplorable way of doing business, in the end I was spoken to in such a tone that was contemptuous and dismissive and no, I never raised my voice or acted in manner that was anything but polite. It would appear self-evident that All Drive Subaru believe that as potential customers it is our privilege to be dealing with them.

    Was referred to them by a Subaru specialist workshop and I will certainly be making my feelings known to them in regards to ADS attitude and lack of professionalism.

    After our Forester engine blew up, we chose an ADS Level 3 remanufactured engine. Never has our car been so thoroughly inspected as ADS did. They sent photos of every part that needed to be repaired or replaced and we were amazed at the poor condition of some. Tomas and Robert gave us much advice along the way and communicated frequently to keep us fully updated re work and costs. We followed all their advice on what should be done and are extremely satisfied with the finished job - completed a week or so sooner than expected. We were most impressed with their factory when Robert took us through it. Two fills of fuel show the consumption to be 9.2 and 9.1/100km. We'll add a review in 12 months time and trust it will still be a glowing one.
    Thanks to all the ADS people for the great job done.

    After going through multiple performance garages having issues with aftermarket tunes, Gab at ADS was able to diagnose and isolate the mechanical faults that were contributing to a lot of my problems not picked up by previous mechanics/tuners. Car was given the full treatment and new tune and has never driven better! Thanks again to Gab for putting a smile back on my face when I’m behind the wheel of my Rex. Absolutely would recommend ADS to anyone.

    The guys at All Drive Subaroo were helpful with the selection of gearbox to suit my car and plans for it. The price was really good and the box was built for me in less than 2 days. They sourced Subaru genuine parts I needed and had all of it packaged up ready to pick up. Top quality work by top blokes. Thanks for helping me to get my car back on the road.
    The staff were terrific. Knew what I needed and could afford.

    Such a relief to be back on the road feeling secure that the Gearbox will do what it is supposed to do.

    thanks guys, and the mum who answered the phone sometimes.

    Big thanks to the guys at ADS, they saw me on short notice to prep my STI for a track day, sent me progress photos and kept me up to date regarding pick up. They go above and beyond, more so than your dealership or standard mechanic and make you feel really comfortable about leaving your car with them because of their attention to detail and quality work. Highly recommend!
    Recently we had to sort out what to do with our ageing Subaru MY 07 Liberty GT that we have loved for many years: repair or sell?
    A Subaru Service centre in our town, couldn’t help in our decision; it’s just getting old!!
    All Drive Subaroo in Peakhurst was our next stop. We ventured from 100 km away and were greeted by the best customer service person we’ve ever had to deal with in over 30 years.
    He was welcoming and courteous and promised to return the car that afternoon with an answer.
    We highly recommend that if you’re in Sydney,or elsewhere, and you have a Subaru, get it checked by All Drive
    Subaroo.
    That’s a slam-dunk: you’ll get the best service the best attitude and honest answers. Overall, a great experience.
    Chris I would like to thank you along with Issac and Niazi and all involved in getting my sons car back on the road for him.

    Unfortunately it was left up to myself to make arrangements to have his car repaired due to the long hours that he works and the stress that he felt he was under given the fact that he had only purchased the car in the last 3-4 weeks using all his savings to do so.

    I choose Alldrive Subaroo after doing some research online and reading all of the positive reviews.

    Being 53 I personally had no experience with these types of cars (I have added some photos of my cars to show how far my knowledge is with these WRX cars so you can understand)

    I can say that I was treated from the start to the finish like a VIP everything was explained to me in a manner that I could understand as well as all cost upfront.

    Its very rare these days to get the service that I received from every one that I spoke with along with pictures sent of the engine building process.

    All this gave me full confidence that you guys were doing the right thing by me knowing that I was six hours away lack of any knowledge and a father willing to do what ever was needed for his son.

    My son will be given strict instructions that his car is only to go to you guys for any maintenance/service needs that it may require

    Truly Thankful

    Rang these guys today for some technical advice. I am in South Australia, so can't call into their workshop. Rob was extremely helpful and took the time to talk me through some possible faults and steps I could take in diagnosing and repairing my sons Forester. Genuinely helpful and know their Subaru's. Will be calling again if I need the parts to repair. Thanks Rob.

    Just wanted to express my gratitude and big thanks to Gab from All Drive Subaroo. Upon having to pull over to the side of road due to engine acting up and not knowing the problem whilst waiting for a tow truck. Gab pulled over to offer his help, I was surprised by his kindness to offer on helping. After diagnosising the problem and temporarily fixing it, I was very appreciative of his dedication to help others in need and expertise. Again, thank you for your help tonight Gab. Would recommend All Drive Subaroo roo for all other fellow subie owners!

    I called up for advice having just bought my first Subaru, a clean white 04 liberty sedan 3.0SpecB six speed manual, (pre facelift, non-centre diff control) and had questions about the viscous coupling and gearbox, and the amazingly helpful bloke on the phone couldn't have explained it better or more simply, aftermarket LSD's, their own uprated viscous couplers, how to test the viscous coupler (by jacking one wheel and trying to move it, smooth resistance is what you want).
    What more could you ask for?
    I'm looking for more advice having just bought a 2.5 '04 wagon 5spd with low range, as a replacement for the sedan whose nose was broken, whacked by a young girl texting and driving her Mazda.
    I'll eventually give All Drive Subaroo some money for their services, gladly.

    Fantastic to Deal with. They know the product. Amazing
    I had planned a track day with my GC8 WRX STI on Sunday, so took it for a quick drive around the block on Saturday to make sure it was running ok. 5mins into driving it wouldn’t rev cleanly over 3000rpm. I’ve had issues with this before and thought my Sunday Track Day was over unless I could find someone to fix it on a Saturday?? All Drive Subaru was open so limped the car out there where Isaac had a look over it for me. After diagnosing what could be wrong he systematically looked at about 3-4 issues which was causing the car to do this which he explained to me as he went through them. This took 2.5hrs which was 2.5hrs after he was meant to finish his shift and leave but stayed because he wanted to find the solution to get my car running so I could get to the Track Day on Sunday. Needless to say after 2.5hrs of not rushing but fixing the problem and any associated problems which could have arisen on my Trackday the car ran perfectly. I went to leave & fix them up for the 2.5hrs Isaac had spent on my car and Niazi and Isaac said “Don’t worry it’s on us”!!! I would have been ready to pay anything for their effort and getting me to my Trackday the next day where apart from being disappointed I would have lost $300 not being there. I didn’t want to leave without paying for there service but they insisted.(I had never been there before). I’m actually blown away by a business that provides this type of customer service that is so genuine, honest and passionate. These guys are next level in knowledge, quality and honesty as a business and Subaru’s. I’m definitely a convert and will be using these guys for all my existing and future needs as I develop my STI.

    The stock gearbox in our 2006 WRX failed recently. After looking around we found All Drive Subaroo. We live in Darwin so organising over the phone and via email was essential. The staff at ADS were fantastic, from quotes to general information to best setups, delivery and everything in between. For what we got, price was good. Very happy customers and very impressed with the new STI box and configuration.

    If you want the best in everything, here is your absolute go-to Subaru workshop. I have all new diffs and transmission that have transformed my car into something more capable and durable than anything you will find in a showroom for any price, and my car does get tested in rough rural situations on a daily basis. Too many improvements to list here, but new engine is next. ADS workmanship is second to none.EDIT: It won't let me add another review, so I guess I have to edit this one.I got the ADS "level 3" engine upgrade for my Forester! My old one was a 2 litre but this is a 2.5L "hybrid". You won't get this engine anywhere but ADS and it's an absolute gem!Overtaking on rural highways is a breeze now, not something that takes minutes of tactical planning anymore. I can launch up motorway onramps to merge easily at traffic-matched speed.The engine is very responsive and 5th gear can be used quite readily because the engine has the torque to pull it, even with my longer-legged 0.738:1 overdrive that ADS previously did for me along with the diffs and gearbox. The extra torque I'm putting through those two Torsen LSDs is still handled beautifully even when giving it heaps around a gravel corner. Grips like a spider running up a curtain, as I like to put it.Attention to detail, communication with the customer, and quality of work are second to none. That goes for the driveline work I had done last time and this time for the engine. I travel 250km to take my car to ADS because I get ultimate piece of mind when I drive away, and that's important when you live rural like I do.Will be back ASAP for the WRX brake upgrade and get my tired old steering looked at. Absolutely brilliant turn-key experience.

    the team at ADS were great, helped me get a staged plan together in line with my budget on building a fantastic car. 4 years and 40,000kms later it still runs as well as the day i got it back, after sales support was also good. can really tell they take serious pride in their work. and the motor absolutely rips.

    I am very happy with the assessment of my 11 year old car which I knew had problems. I decided to go ahead and repair/replace items for my car which meant I did not have to purchase a new car. My car runs so much more smoothly and much quieter. It is also a much safer car to drive. Patricia

    These guys are absolutely fantastic. I have been having some issues with my car for some time that my previous mechanic couldn't be bothered to diagnose, let alone fix. ADS diagnosed the issues pretty much instantly, and were very helpful and transparent regarding my options for the large repairs required. Rob was fantastic to deal with, and was willing to answer any questions I had. He also helped me to prioritise the repairs I needed now over others that could wait, and gave me complete choice in everything. Thanks so much Rob! My car feels better than it ever has before, so I'm so grateful for the skills and knowledge these guys possess. Do yourself a favour and never take your Subie anywhere else!
    Since ADS has done the work on my Impreza the engine is great, the gearbox is working really well - especially on the hills. The Subaru is a pleasure to drive. Plus good people are working there who obviously know their trade. Every dollar I have spent there has been worth it. I highly recommend ADS.

    I made the leap from dealer Subaru servicing to ADS and won't be looking back. What a drastic change this was. From easy booking process to the servicing and to pick up, Robert is absolutely exceptional and the place is extremely friendly and professional. They really took great care in explaining the issues and the service process. The prices are fair and reasonable and I haven't had a Subaru service before where I have walked out already wanting to book the next one in. Car drives great now. Thanks again to Robert and the ADS team.
