Re: Water Pump
When you do the change, note the refill procedure I used on mine in Post No. 14 on this thread: http://www.jeepgarage.org/showthread...393#post585393
It'll make your life a lot easier. I use a 50-50 mix of HOAT type antifreeze and distilled water. I always premix mine in a gallon jug. That way you can use what's left to top off as I indicated. If you're just changing the water pump it shouldn't take a gallon. When I changed the cam on mine it only took about a gallon and a half. Like Chaoul1 said, you'll need the HOAT (don't use anything else) antifreeze, distilled water, the pump comes with a new o-ring and a new thermostat or a Felpro 35840 housing gasket. This is the only one I've been able to get to work without leaking. If you can't get that gasket (it's thicker than most) get a new thermostat from the dealer. Theirs is the only one that comes with the stock o-ring. The o-ring is the sticking point. You can't (at least I've never found it) buy the o-ring separately and if you buy just the thermostat from anywhere but the dealer, it doesn't come with the o-ring. Go figure. Good luck and let us know how it goes.
