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.

SOURCE: My 2001 Ford Windstar van seems to be using alot of coolant daily

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.

More then likely the water pump is starting to go bad. They leak thru a weep hole on the bottom of the pump that is not readily seen

SOURCE: my 2000 Windstar runs well for first 20-30 mins then it starts to have engine knock it is also using oil but not burning it. Doesn't smoke doesn't show any signs of leaks under car either

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:)

Coolant leak from radiator and white smoke coming from the hood.

Sounds like you have blown a head gasket. Do not run the engine like this or you will seize it up . anti freeze will freeze the pistons and you will need a new engine. Hope you have not ruined it now.
White smoke is a sign of water in the piston area.

Why would oil be in my coolant?

Oil in coolant, white smoke at start up = blown head gasket or cracked cylinder.

White smoke is water vapor from coolant. Only at startup indicates a small (extremely small) leak -- it will get bigger. Only at startup is because as engine cools it sucks water into cylinder. A compression check will tell you which cylinder is the problem (could be multiple)

94 Ranger 4.0 L V6 , manual transmission. Already replaced water pump and thermostat and ran water through the radiator to check for flow problem. Truck still overheats and the heater doesn't work. I...

First you need to purge the trapped air out of the system. Go to a shop that has evac/fill equipment and tehy can do it for about $75. It is ahrd to get air out. park uphill and rasie front of truck as high as possible, and keep cap loose during warm up. It will burp air. Then tighrten cap & let it cool while keeping the reservoir full during cool down. Repeat at least once. Make sure hose from rad to reservoir is tight at both ends to avoid sucking air in.

report results.

please rate if helpful

No heat is a sign of trapped air.

Car over heats both fans working and i have a new thermostat.Even checked water pump to make sure it's ok. very frustrating1!!!!!

Flush coolant system out. If this does'nt help check for white smoke coming out of exhuast while its running.White smoke from exhuast would mean that coolant is getting into one or more of the cylinders,which would mean more than likely a blown head gasket.A blown head gasket would cause it to over heat.If you are loosing coolant and don't no where its going would be good sign that its blown.You would need to proform a leak down test on each cylinder this would let you known which cylinder is the problem.

White smoke coming out of exhaust, engine not overheating loss of power does not appear to be losing water

White smoke from the exhaust is a sign of coolant entering the combustion chamber. You say no coolant loss, or overheating. Is there a white foamy substance under the oil cap, & air bubbles escaping from the radiator? If so you have a leak and more than likely it is a blown head gasket. I would have a cooling system pressure test run. Do not continue to drive this Ford in this condition. Something is not right and you need to find out what is going on.

98 explorer sputtering and white smoke from tail

Hi Dre,

I hope you don't shoot the messenger, It sound like a blown head gasket.

The white smoke is water in with the combustion.
The rough running is either no compression or coolant in with the fuel/air mix.

Things to check to confirm.
  • When cool, take off radiator cap. is fluid low? Get everyt one clear and start the engine. Does coolant erupt out of the radiator?
  • Run a compression check on all cylinders
  • While the plugs are out, inspect cylinders (flashlight) for water.
  • Check oil for a milky color
The little bit of good news is it still runs. So secondary damage hasn't occurred yet. You need to get this addressed quickly.

I'm sorry to be the bearer of this type of news.
