ive gone through a full gallon of coolant just keeping it in the safe area. needless to say this is quickly becoming less than cost effective. there is no puddle beneath my car where i park it everyday so where could the coolant be going?

Last time I had that issue was on a Mazda Pickup. It was a Blown head gasket and the coolant was going out the tail pipe. I didn't catch it until I smelled anti freeze in the exhaust.

with a 2000 xj, you have one of the heads that are "common" to crack. I bet your oil looks like a milk shake and if it does not, then you can smell the sweet sugar smell in the exaust.

Im betting you have a cracked head.

oil looks fine but it was recently changed. ill take a closer sniff at the exhaust tomorrow and i scheduled an appointment for next week. is it alright to be driving, and what do i need to do to make it the best i can until it gets fixed and could it possibly be anything else (the fact that all three of you said the same thing doesnt make that seem likely) maybe just a thermostat problem?

thanks for the help-brad

white exhaust is typically a sign of a blown head gasket... are you overheating at all? pull the radiator cap and start it up. if the coolant bubbles, but is cold to the touch...you have combustable gases in the coolant...bad head gasket.

As a former Chrysler Certified Technician and a current auto tech, stop leak of any form is bound to do more harm than good. But if you must resort to it, try and find a pure liquid stop leak. Cheaper ones with silver/copper flakes cause more blockages than one might even believe. Trust me on that one.

If its a cracked head or a bad head gasket I don't think putting stop leak will do anything except gunk up the radiator IMO. Sorry...Tj
