Hi All!
have only owned my TJ for 6 months and when I first got it, found that not only did it have the wrong antifreeze, but the thermostat housing was leaking as well. so I took it all apart, flushed the motor (4.0 I6) and installed a new pump, thermostat housing and hoses.
To my chagrin, when I pressure tested it, I found that i could not get the thermostat housing to seal against the head without shimming with a very thin piece of gasket material on the side that looks to be a bypass cavity.
the surfaces were cleaned thoroughly and i was using new gaskets as well as RTV but could not stop the leak until i added the extra gasket material.
anyone else have this problem?
