dvto2 Posted October 15, 2018 Share Posted October 15, 2018 My son's 2002 Legacy sedan is leaking radiator fluid. He says it's coming from the radiator and not one of the hoses, but I'll see tomorrow when i pick it up. Assuming he's right, and i need to replace the radiator, should i go with a Denso? Also, can i go with Rock Auto's green pentosin or do i need to stick with genuine subaru coolant? Link to comment Share on other sites More sharing options...
RumbleRumble Posted October 17, 2018 Share Posted October 17, 2018 Check the top and bottom plastic tanks on the rad for white residue I got a 100$ spectra branded rad on amazon and it's been working fine for 4 years. Subaru OEM coolant if that's all it's ever had. Pentosin is a good brand but not sure if there green coolant is on par with OEM subaru. Link to comment Share on other sites More sharing options...
dvto2 Posted October 18, 2018 Author Share Posted October 18, 2018 I went to the dealer to get oem coolant and the parts guy said said they don't carry green coolant any more, and that any green coolant should do. Link to comment Share on other sites More sharing options...
RumbleRumble Posted October 19, 2018 Share Posted October 19, 2018 (edited) That guy's a tard. You can still get green coolant he just didn't stock it...... and no not all green coolant is the same. Most parts guys know nothing. Subaru coolant is far superior in quality compared to prestone or peak. If you flush whole system you can run blue.

bmart Posted May 10, 2021 Share Posted May 10, 2021 Can anyone verify if DENSO 221-3601 radiator fits both auto and manual transmission 2000 Legacies? i'm getting conflicking info that they use different radiators, although I have no idea why. Thanks. Link to comment Share on other sites More sharing options...
RumbleRumble Posted May 16, 2021 Share Posted May 16, 2021 If you have a auto car then you want your rad to the have the two ports on the bottom middle for the trans cooler lines. Manual cars can use either. Link to comment Share on other sites More sharing options...
bmart Posted May 16, 2021 Share Posted May 16, 2021 Thank you! I installed the Denso the other day and got an OEM cap. Back on the road! Link to comment Share on other sites More sharing options...
