rendoll911 Posted September 10, 2014 Share Posted September 10, 2014 (edited) Car is a 96 Legacy 2.2 with 90k miles. My resevoir has been slowly leaking, from full to below the low mark in about 2 months. I can't find any external leaks, but the bottom of my engine is an oil field due to a leaking oil separator plate, so it's hard to diagnose a slow leak. I took the resevoir off and pour out this lovely sludge which was sitting at the bottom of the bottle. (pic 1) I also noticed this soft grey buildup under the radiator cap (pic 2). I plan on flushing the radiator, but should I be worried about headgaskets or some other costly repair? Thanks for the help guys! All i know about cars I've learned here.

ocei77 Posted September 11, 2014 Share Posted September 11, 2014 Spray bottom of warm engine with degreaser. Let sit for 5 minutes then hose off. Do again, this time with a brush of some type. This will clear most of grime so you can check better for leaks. Flush the radiator system. replace T stat with an oem unit or a Stant Xactstat unit only. Then see how your coolant issues are. Read up on how to "burp" the coolant syatem properly. O. Quote Link to comment Share on other sites More sharing options...
