BVickers Posted January 8, 2012 Share Posted January 8, 2012 Hello, I am new to this board and would like to ask for some help or ideas. I just purchased a 99 Legacy Outback with 2.5l and 196,000 miles. Car ran great except the temp gauge never moved unless in town. I decided to replace the thermostat. Upon removing the housing I found NO thermostat in place. I replaced it and now this is what happens; Temp gauge sets at normal operating temp unless driven or runs for 20 plus minutes. Then pegs out. The antifreeze and radiator are cool to the touch except the end by the upper hose. I have burped the system even using a rolaid to hold the new thermostat open till it warmed up. I have hot air from heater until the gauge starts to climb past normal, then it goes cool. There is movement in the overflow tank. No fluid leaking into the oil. I have read alot about these having head gasket problems. Could this be? Or could it be a bad temp sending unit? I have a 99 Subaru Legacy with 198,000 miles on it with a 2.2l and have had no problems with the head gasket. Any ideas what else to try? Link to comment Share on other sites More sharing options...
Stang70Fastback Posted January 12, 2012 Share Posted January 12, 2012 Well the 2.2 doesn't have the head gasket issues of the 2.5 in the Outback. It sounds like someone pawned off a head gasket issues to the next owner if you ask me. Kinda sucks Link to comment Share on other sites More sharing options...
