Title: Thermostat Gasket - Not listed!? 2004 Rubicon
Post by: Tinkerer on September 25, 2008, 06:34:34 PM

I went to two vendors, one of which I usually find pretty reasonable, but both of their systems said that there was no gasket listed for a 2004 Rubicon with 4.0L inline 6!  They had thermostats... they seemed to think that the thermostat for a Rubicon is different than that for a non-Rubicon, which I sincerely doubt. The Stant website doesn't distinguish between the two at all.

Any ideas? If I can avoid using "make a gasket" as the sole gasketing material or cutting my own from bulk material (if I can find it in my garage), I'd prefer that.

PS: This is coming up because two mechanics have suggested that my random overheating symptoms are most likely due to a sticking thermostat.  I have burped the system and done all kinds of other testing etc. and just sometimes while cruising at a constant speed on a flat portion, suddenly it will overheat, then cool back to normal again almost instantly.  Electric fan, which has been working properly etc.

Thanks!

dealer will do you right, the parts guys are probably just confused - tell 'em its an '04 tj 4L and they probably got one under the counter ...

on the subject of dealers ( which has a inherit bad rap from the '60s man  ::) ) ,  in the times I have compared prices they are very competitive least 1/2 the time ... and next day delivery is always an consideraton for those times when you feel gouged ...

A proper gasket is good but there is nothing wrong with a silicon gasket there.  Just use a good quality silicon like permatex ultra grey.
