Installing a CVT Cooler Thermostat in a Subaru Crosstrek

[@chipper7711]

Oops - you wrapped your TFT tape backwards on threaded fittings 😮

[@Supercheeze0123]

Really appreciate your in-depth videos on the topic, I'm trying to tow-proof my crosstrek so that I don't have to worry about blowing the transmission up. I would've never thought about an oil cooler if you hadn't mentioned it here, I'm hoping you make a video on that soon but I know you said you're pretty comfortable where your car is at now.

I run a Hayden Automotive 699 transmission cooler with a built-in thermostat that also allows transmission fluid to cool at 180F. It's a plate and fin type cooler and isn't overkill like the Mishimoto cooler. Also, there is no need to use a remote thermostat because there is an internal thermoststic bypass like I mentioned earlier, with less leak and failure points. Finally, I have a SPAL 7.5 push fan for slow, off-road driving, and when I don't have positive airflow to cool the fluid. I've been running it for 3 years with zero issues. Of course, with extreme abuse, replace the CVT more often to increase longevity of the transmission.

The way you explained and labeled everything in the video with arrows is great. I am installing this same thermostat this weekend and this video helped me out a bunch. Thanks!

[@Superkrill]

Best CVT temp mod video ever. Big thanks.

[@scothendrickson9877]

In any case, thank you for this otherwise GREAT turorial.

[@artilleryisbetter]

Very good job explaining this application

[@Stickler-ish]

Error. Good, detailed, and informative but (beginning at 8:40) you show wrapping the tape in the wrong direction!

[@ironman1518.]

Thank you excellent explanation!

[@scothendrickson9877]

Per the Derale document, it appears you have installed the thermostat backwards...please advise...thank you.

[@DustinDIY]

didnt see this... wrote same comment

[@jacoddeoca2764]

Really good video 👍👍👍

[@Moatasem995]

‏Greetings to you and thank you very much for this wonderful video that I was looking for this type of video ‏I have a question why is the CVT Transmission Oil Cooler quad is used instead of cancelling and direct connection?? I hope your reply and thank you very much

[@dm19609721]

if the ideal temp is between 175-200 degrees that is hot....you say you want the fluid to be warm.....175 degrees is hot......140 hot water will give you burns....imagine what 175 degree fluid will do....I had a regular car with an oil cooler and even when it was 90 degree F outside the AFT fluid never got over 140 degrees.....the transmission was original....reg fluid changes and shifted like a swiss watch after 200,000 miles. Problem with the car was age and rust caused by excessive road salt

[@WolfKingJS54]

Does the kit come with instructions of how to route the hoses like what attaches to what

[@anthonyjulson8840]

Did you notice a difference in your mpg?

[@elsocio666]

Look on the official Setrab website for Setrab ProLine oil coolers. I currently have a 16-row STD series 1 installed, with a 4" Spal electric fan, housed in the subframe next to the transmission. My setup is without a thermostat since I live in a hot climate. I have an XV MY 18 and my driving is mostly mountain (severe use). I liked your video analysis.

[@Stephen-vy1gp]

Do you need to add more cvt after doing this or no?

[@IIBundo]

I wonder if you can use the same CVT cooler that comes in the 2024 Crosstrek Wilderness.

[@aarshmathur2909]

Would you still use the thermostat with the smaller mishimoto cvt fluid cooler

[@GrotesqueRomance]

Do you know approximately what your towing capacity would be with this settup? I only ask because the crosstrek wilderness has 3500lb capacity, and I’m wondering if the new cvt cooler in that model is the main reason. Also love this video and everything I learned from it. Thank you!

[@DarthGengarus]

They say it’s 3500 due to the cooler. It’s same engine and same transmission minus some slight difference gear ratios I believe. But basically it’s exact same motor/trans and added a cooler.

[@rohitnagare8187]

which hose you used? could you share the link please?

[@tarast52]

I haven’t got a 2022 Subaru outback with a 2.4 L turbo will this kit fit my car

[@DustinDIY]

thermostat looks backward. directions show larger bottom as hot in. smaller top is from cooler

[@neildeatherage2269]

Purely anecdotal but my '16 Forester 2.5 always seems happiest around 160 F. After 180 it just doesn't seem as confident which quickly kills my confidence lol

[@metaframe2k]

Sad to see Subaru's decision for the US market. For Europe and Russia, Subaru from the factory puts additional CVT oil cooling in the circuit of a regular radiator, to which additional steel pipes and hoses fit. As for the heat exchanger on the CVT, it is not developed for cooling! It is designed for faster heating of oil, especially in regions with cold climates.

[@Superkrill]

Could you kindly elaborate a bit more about the " additional CVT oil cooling in the circuit of a regular radiator, to which additional steel pipes and hoses fit". Thanks in advance. By the way, the reason I asked was because I could not find specfic CVT cooling circuit info or diagram for the 2017 onward Subaru XV or Crosstrek.

[@metaframe2k]

@@Superkrill You are absolutely right, this cooling system is not in the original Japanese schemes. But these details exist in nature :), here are their numbers: Pipes: Subaru 21623-AA090 -1 Subaru 45520-AG010 -1 Subaru 45520-AG110 -1 Subaru 45520-AG100 -1 Subaru 45520-AG030 -1 Subaru 45522-AG040 -1 Radiator with integrated gearbox cooling circuit, two pipes at the bottom of the radiator Subaru 45119-SC040 (use google serch to see picture) Fitings: Subaru 21326-AA210 -1 Subaru 80191-4040 -2 Subaru 80391-40605 -2 Subaru 11024-AA070 -1 Subaru 80391-4060 -4 Subaru 01041-0200 -1 Subaru 80691-1080 -2 Subaru 04740-6120 -3

[@Superkrill]

@@metaframe2k Wow...big thanks for your prompt reply. I will closely look into all the precious info you provided. Very much appreciated.

[@HardLinesFunTimes]

So I had a cvt cooler installed and did you experience any humming at speeds of 65mph underload even when releasing the gas pedal?

[@elsocio666]

I am experiencing a noise similar to the one you describe, just when releasing the accelerator in my 2018 Subaru XV. By chance have you replaced the cvtf fluid?

[@HardLinesFunTimes]

@@elsocio666 so the problem for me was the shop I took it to too have the cvt cooler installed also changed my differential fluid and they forgot to put in the rear differential plug back in. I called them and they replaced my rear end.
