Question about 2000 Ford Explorer
Help !! My explorer is loosing coolant. Engine runs fine, doesn't over heat. No white smoke or water from tailpipe. No milky stuff on oil dipstick. Heater works fine. Only leaks when hot and I can hear and smell coolant leaking onto exhaust after driving. Underside of engine on passenger side of vehicle damp. No visible sign of leak.I am loosing about a reservoir full every couple days. No smell inside vehicle. I have searched internet and found several possible causes, some which worry me alot due to limited finances. V6 4.0 SOHC
Unfortunately this will be kind of hard but, it sounds like you may have a blown head gasket depending on where on the passenger car it's leaking? Drive the car get it hot. Leave it running get out and pop the hood. Start looking for leaks. Use a powerful flashlight to help look. If it doesn't leak while you're driving and only after the car is shut off then I'd say you're creating a vacuum in the coolant system, change your coolant cap at that point.

Possible coolant leak on hot engine parts causing it to evaporate as it leaks. That would definitely invade the cabin air.
You would need to carefully check under the hood with the engine warmed up and running.
Also could be a headgasket failure between coolant channels and a combustion chamber. This latter problem sometimes shows itself as vapor at the tailpipe after there should be no more visible. You may also detect the odor of coolant there too.

Ford water pumps have a "weep hole" on the bottom of the water pump. When the bearings go bad the coolant will weep from there. Also you may just need to get in there with a flashlight, probably from underneath the truck and see exactly where the steam is coming from. Check all the heater hose attachments and the radiator hoses. If you are lucky it may just be a worn out hose.

Check your engine coolant. If its brown you may have a blown head gasket which is causing it to leak into the cooling system. (expensive fix) but if it's not brown I'd take it to a mechanic and have further inspection. Hope this helps:)
