GeneralDisorder Posted January 17, 2022 Share Posted January 17, 2022 (edited) Plain old green anti-freeze. The cheapest stuff you can find. Mix it with distilled water at 50/50 concentration. Why on earth would you put expensive dealer anti-freeze designed for 10 year newer cars in a car that *you know* has head gasket issues? And yes - the blue OAT coolant eats plastic. Especially plastics not designed for use with it. Subaru says you CANNOT mix the coolant types even if you flush out the system completely. IMHO the blue coolant is junk - it's 3x the price and we never had any issues running green coolant in Subaru's for 40 years prior. With all aluminium engines they are not demanding with regards to anti-freeze. GD Edited January 17, 2022 by GeneralDisorder Link to comment Share on other sites More sharing options...

heartless Posted January 18, 2022 Share Posted January 18, 2022 yup, just plain old green stuff - save yourself a bunch of headaches and buy the premixed ready to go stuff - 2 gals should be plenty install the radiator, hook up the lower hose, but leave upper off temporarily... raise the front of the car, and pour antifreeze in the upper hose to fill the block, attach hose, and fill the radiator, wait a minute or two, top up, etc, until you cant get anymore in. dont forget to fill overflow bottle to the correct level with front end still raised, run the engine to full operating temp (rad cap on). Shut car off and let it cool completely. DO NOT try to open the cap hot.. when it is completely cool, pop the cap, top up as needed, and check the overflow. should now be ready to run.. carry any excess coolant with you for a week or two just so you have it if you need to top up the overflow.

ThosL Posted January 18, 2022 Share Posted January 18, 2022 A couple months ago a nice black gentleman who had a totaled 2001 Forester in his driveway, said it was in great shape mechanically for $100! I had no place to put it and didn't need that. Probably could have flipped it at a tidy profit as good 2.5 engines are hard to find. I went back last month and it was gone. There are opportunities around if people will follow up on what they see like that. Some people are too busy to put them online. Link to comment Share on other sites More sharing options...
