hey guys, just got done changing the coolant. was leaking from bottom of thermostat housing a little. so i changed the o ring, filled up & ran for a little bit. still leaking a little. i KNOW it's not the intake runner. just on the bottom of thermo housing. thermostat sits in it's hole, then o ring on top, then housing. think it would hurt to take back off & put some gasket sealer on thermo housing?

 

i have a 98 gt also and im just now having the same problem i talked to alot of people and they said its the intake manifold i tryed to change the same thing and its still leaking

 

the mechanic i work with came by & he gave me some of the good sealant he uses. we'll see what happens.

 

make sure you torque your bolts to the correct torque, and use correct gaskets :-p
