If the coolant loss happens when the engine is not running, and there are no external leaks, it has to be going into the engine. And its probably leaking while the engine is running too.
You can burn a large amount of coolant and never see it come out the tailpipe.

Testimonial: "I checked that, and I've been keeping an eye on the oil.It's an external leak I can't find...After the engine's shut off, you can hear and smell the coolant hitting the exhaust manifold.The compression and plugs are good,no signs of water in the exhaust. Only for a minute and only when the engine's shut off. Weirdest thing. I've been a mechanic before during and after I studied electronics, but this?? I can't think of what is builling all that pressure after the motor's off??"

look on the back of the sleeve the serpentine belt came should have multiple diagrams showing the setup you just have to choose the one for your engine. to replace unbolt the back of the alternator remove the belt and work backwards to install belt.

you have to pull on the belt to get give from the tensioner unless you have the required tool... it makes it A LOT easier but nothing a little elbow grease cannot handle

SOURCE: 2002 Ford Taurus has no heat

Look for a blocked heater hose (kinked, pinched, or collapsed), or a valve (either electrically or vacuum controlled) in the line that isn't opening. Feel both hoses when the engine is hot and set for heat. One should be hot and the other cooler when operating normally. If both are cool, then something is blocking water flow through the heater core.

Poor Heating in 2000 Ford Taurus, Recieving cool Air through Blower

First place to check is the thermostat. It's like a float that allows coolant to pass from the hoses through the block. If it gets stuck, you'll lose heat. Easy to replace, and inexpensive.

How do i fix an air lock in cooling system in 2002 ford taurus ses?

There should be air bleeders near the thermostat,and another one else where on the engine at a high point,Break one bleeder loose,(thermostat location) first,with engine off,and pour coolant into the reservoir ,and when the bleeder runs pure water no air bubbles out,then shut the bleeder off.then do the same with the other bleeder.Sometimes allowing the engine to run,until normal engine temp,or a little warmer,and turning the engine off,will allow the cooling system to bleed itself,by waiting about 30 minutes and checking the coolant level in the reservoir to make sure the level is dropping,then u will know the system is bleeding itself,just make sure there is enough coolant in the reservoir before doing this.This may have to be done two,or three times.

No heat in a 2002 ford taurus, need free information on how to fix myself

If it's not the thermostat I have seen this happen numerous times in Fords. The engineers, in their infinite wisdom, placed the heater core HIGHER than the engine block. The coolant gets low and ya get an air pocket in the core. The fix...drain cooling system, remove t-stat and drill a small hole in the flat part, reinstall it with hole straight up (It's an air bleed, if ya didn't figure that out), refill the system NOT THE REGULAR WAY!!!! Remove the hose that runs from the engine to the heater core. Use a funnel and SLOWLY pour coolant in, until the reservoir is full. This will eliminate the air lock in the core.

Blower working but dont have no heat i changed the thermostat still not working im hoping its not heating core any suggestions

if the cooling system is not clogged and the water pump is ok then there may be air trapped in system, bleed air from system if need be. if air is trapped in system you will not get any heat. start car let it run take cap off of coolant tank then find bleeder for the coolant system, open bleed screw and air may be trapped in system.make sure coolant is at a proper level. do not forget coolant tank cap when done.

Ford Taurus 1996, coolant comes out throughout the cap every time when car stops

You will overheat the engine if losing coolant.Firstly replace the cap with a new one,Is the engine temperature normal when you stop ? If its over temperature it will still blow out coolant. Check the radiator for blockage of the tubes & ensure the fan belts and water pump are in good order. Worst case is a blown head gasket can test for combustion gases in the coolant

99 Taurus heater not working.

sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.

i would suspect a couple things. if the engine is not running at correct temp. 195 degrees or so. replace thermostat and recheck. if engine is running at normal temp and is not overheating at all. would suggest flushing heater core to see if helps. if not then heater core replacement may be necessary these ford cars and trucks are notorious for poor cooling/heating systems due to the coolant used
