My poor 2003 Forester has been through a lot. Since I thought I was going to have to replace the engine last winter, and didn't (see other posts), I was hoping for smooth sailing. Then the coolant started leaking. Just got it back from the shop and no, it could be a hose. No, it's coming from the left side head gasket. Had a pressure test. Put in sealer an I hope to get it to spring without more problems so I can decide what to do. I only drive about 5K miles a year. It has 156K on it. If I decide to do the head gasket, what else should I go ahead and do at the same time? I bought the car in 2010 and the timing belt had been replaced and the paperwork said it would be needed again at 205K miles. I kind of hate to buy another used car because I don't want someone elses headaches, but am getting tired of the expense of my subaru habit. I've had 1 replaced engine, 2 head gasket jobs on 3 cars over the years. Time to look at Honda CRVs? I will fix this one if that is the best option (est. $1200). Thanks!

what sealer was used?

 

external leaks can often be fixed or greatly reduced using the Subaru Coolant Conditioner (a repackaged leak stop) But, I guess I'd wait to see if the product you used works. If not, a thorough coolant drain with a refill using the SCC PER INSTRUCTIONS might be a good next move.

How bad was it leaking? The external drippy leak if needed can often be just lived with by keeping the overflow plenty full and making sure the rad cap is good and checking the radiator level periodically. My '00 had that peeping leak I drove it that way for a few years, just had to top off the overflow every week or so. It would suck in what it needed. (Also have to check the rad level under the cap too though in case it sucks air in somewhere instead of coolant from the overflow). To me it seems like as those era auto trans approach 200k miles the pinion bearing goes out often and then it's like $1500+ to get a used transmission put in and hope that it is a good one.
