Hissy Radiator Hose

Well, this is embarassing.

So, my old radiator hose was leaking like a sieve, so I replaced it.

In the process, the thermostat housing cracked.

I replaced the thermostat housing (and thermostat) and sealed everything up.

Problem is, even with the hose clamp tight (I'm afraid to tighten anymore, with the aluminum T-stat housing), I still get a slight hiss of pressurized coolant that comes out. It is maybe enough to wet a postcard, each time I stop.

Can I put gasket sealer around the bottom of the hose to stop this, or is there some trick I'm missing from the Jeep world?

There is no need to use a sealant or gasket. Just be sure the neck of the t-stat housing is clean and smooth and tighten till it doesn't leak. Seems to me you would really have to crank down hard on it to cause it to crack.

I've only ever had that happen with old hoses that i've taken off and reinstalled and with loose hose clamps. I guess you could try a little sealant around the end of the hose but it should seal up good without it, something is wrong. As said above take it apart again clean thoroughly and maybe se some new, high quality hose clamps, I have had problems with the cheap AutoBone ones.

Good Luck,
Will work for Jeep parts...
