antifreeze leak

[CntStpTheStnk06]

ok so i have been battling my jeep for about a year now.it is a 2001 xj. it seems to always leak out of the thermostat housing it seems like because there is only two bolts it doesnt create a tight enough seal. has anyone else had this issue? i have replaced the gasket 3 times now, each time cleaning it and making sure all the old gasket and crap is off.

[wannabejeep]

is it leaking from where the thermostat meets the block or where the hose meets the thermostat. How's your hose look? If it's shitty maybe its leakin out there and down the block.

[Ktmracer419]

are you 100% sure its leaking out of the thermostat housing? not water pump?

anyway, i have never had a problem nor do i know anyone who has ever had a problem getting a permanent seal there

i'll x2 what sam said. maybe the thermostat housing is cracked?

its not cracked and yes it is leaking out of the housing not the hose.

its not cracked and yes it is leaking out of the housing not the hose.

next time you do a gasket, make sure that you put a thin layer of rtv sealer on both sides of the gasket. works for me

[crosbike]

ya definitely use rtv on that sucka too.

i wouldn't put a gasket on dry for that application... Hi temp RTV

Check the housing for warpage on a flat surface.

use the right stuff...


no really thats what its called... Permatex - "the right stuff"

[CntStpTheStnk06]

i used sealer everytime and as a quick fix cuz i was out i just put the gasket on, no sealer and its holding alot better then it did befor, we will see how long this last.

[Burton58]

mine has always leaked unless i sealed it with something else first

actually the 3m weatherstrip and gasket maker yellow works a million times better than right stuff
