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!
