Hi Scotty, I have a 2006 Subaru Forester with a little over 200.000 miles. Yesterday as I was driving, I noticed the temperature gauce jumping a little bit over the usual place. I stopped and checked the coolant and this is how it looked (photo). Then I drove back home (about 10 min drive), careful to drive gently and after I stopped, I checked again the coolant and this time it looked normal but a lot of bubbles were coming out of the overflow tank.

On the dipstick the oil looks normal, it doesn't make white exhaust smoke.

Could this be a beginning of a head gasket issue or could it also be something else?

I've been quoted for $3000 for a head gasket. This is over the car's value and I don't wish to invest. I saw a video of yours recommending Steel Seal - could that work? And by using that, is there any risk of clogging the radiator or something else?

Thanks Scotty for the input!

head gasket leak city, but do this test, then if positive, get rid of it


U can do a head gasket leak test, Scotty has video. But I am guessing it head gasket. Bubbles is a sign.
