A few days ago, the temp gauge in my 1995 Subaru Legacy went sky high in a matter of 2 minutes. I immediately stopped the car, let it cool down & checked the radiator. The reservoir was empty and radiator took about 1/2 gal of water (I figured water was fine since the weather is 90 degrees here right now). Suspecting a leak, I also added a bottle of that “Bar’s Stop Leaks” stuff. I hesitantly started making my way home, about 16 miles away. The car was perfectly fine – no overheating at all. Next day, I drove the car maybe 10 miles & again no problems. Yesterday, I went to a friend’s house – about 50 miles round trip. I assumed (I know, dangerous) that all was well … until today. This morning I noticed a small puddle of antifreeze near driver’s front tire. The reservoir was down by about 1/2 it’s capacity BUT the radiator itself was almost full (if it took 3 oz. that was a lot). Now I figure there’s a leak, but if there is then why wouldn’t the system drain itself all the way? Is it unusual to have a leak that limits drainage?
I am also tempted to add another bottle of stop leak but looking around this and other forums, I’m not too sure that’s a good idea. Should I? Thanks much!
