how hard is it to get to the thermostat on the 3.9? i was lookin and it looked to me like i would have to take the alternator off and everything. also, do i need a holder thingy so it doesnt leak, or is there like a rubber o-ring?
I did it and it's not really easy but the only thing I unhooked was the A/C. I just unbolted it and kinda moved it out of the way. Gasket should either come with it or they'll just grab it when they get the T-stat at the store.
hey corey the install ins't that hard it just took me awhile because i couldn't get the thermostat to just drop in. i had to get a long screwdtiver and some needle nose pliers to get it to seat right on the manifold. it was harder this way but i didn't have to move any accssories. also how do you like your 40 series delta flow? i was wanting the exact same thing for my v6 and wodered if it was too loud? i at least want to be as loud as these little punk ricers around here!
The thermostat is easy as hell. I've done it twice (once when it leaked through the gasket and the second time for a 180) and it is very easy. There is no reason to unhook ANY accessories other than the hose leading to the thermostat. If you did, it was a waste of time. Don't forget to drain the coolant from the hose, unless you like the taste of anti-freeze.
