ekimyerac Posted July 19, 2006 Share Posted July 19, 2006 I stopped NAPA to get a thermostat for my 95 Legacy 2.2. Took the old one out, and replaced it with the new one and gasket. However, it leaks and I was afraid to tighten the bolts any further. I noticed that the gasket goes around the thermostat, not like the one on my 88. So, what did I do wrong?

avk Posted July 19, 2006 Share Posted July 19, 2006 Did you use a new gasket? Tightening the bolts won't help if the plastic housing is already sitting flat against the pump flange. Quote Link to comment Share on other sites More sharing options...
ekimyerac Posted July 19, 2006 Author Share Posted July 19, 2006 Yes, I used all the new parts. One thing that I noticed is that there is no gastet between the housing and the engine, like on other cars. Mike Quote Link to comment Share on other sites More sharing options...
hohieu Posted July 19, 2006 Share Posted July 19, 2006 You might to check that the seal fits squarely into the housing, that it's not snagged or deformed along the mating surfaces. You could also try cleaning the mating surfaces with skotchbrite pad. If that doesn't work, try installing the seal in the old orientation -- on top of the thermostat rather than around its circumference.

Commuter Posted July 19, 2006 Share Posted July 19, 2006 Careful with aftermarket thermostats. People have had problems. I know on my 97 2.5L that the thermostat 'guts' are offset. It only goes in in one orientation. Some aftermarket t-stats have been known to interfere with the housing. And this may only happen as the valve tries to open, thereby not opening fully and causing overheating. I believe the 2.2L is the same. It's safest to stick with OEM for this part.

avk Posted July 19, 2006 Share Posted July 19, 2006 The gasket is compressed in its bore to pre-determined thickness. For it to seal on all sides, it is important that the groove on the gasket fit snugly around the thermostat. Quote Link to comment Share on other sites More sharing options...
ekimyerac Posted July 20, 2006 Author Share Posted July 20, 2006 Went to the Subaru Dealer got another theromostat, installed it and no leaking. Finished putting in antifreeze and it seems to work. I ran it for about 45 minutes and it did not get hot, seemed to get hot when the vehicle wasn't moving. Fans all work, heat out of the heater. So we will now wait and see.

Mike, KD7GHZ Did same thing on my 95 legacy. The thermostat did not work well, did leak, and finally purchased OEM thermostat. Problem solved. Did same thing with spark plugs. Purched nice Bosche platimum plugs and the car skipped. Went back to OEM plugs, problem solved. Have discovered that Subaru knows what they are doing and the engines are tuned to the specific parts. From now on I will put in OEM parts period Monk50 Quote Link to comment Share on other sites More sharing options...
