Exhaust Converter Blocked ?

Did you check for combustion gases at the
coolant or radiator fill

Your down to a head gasket or a crack somewhere

I would think the head gasket is common on that
motor possibly,research that

Timing Belt worn or jumped ?

    Timing belt was changed and so was the head gasket. Someone told me it could be a sensor. The needle on the temperature is ready hot but the radiator cap and the hose all feel cool to the touch. I did find a small leak of antifreeze due to a hose that needed tightening so I hope changing the sensors work! Thanks for the info.

SOURCE: 2002 mercury villager water circulation problem

Check the new thermostat by putting it in a pan of water and bringing it to a low boil. See that it opens. It is possible to get bad parts off the shelf.

SOURCE: 1999 mercury grand marquis occasionally overheats,

Check the antifreeze for oil, pull your dipstick out, see if antifreeze is in oil or smells sweet or over full, sounds like you may of a bad head gasket. You can also check this by having a compression test done on the cylinders.

SOURCE: identified leak in intake manifold

I'am sort of missing something here

Was the radiator blocked or replaced as a guess ?
The thermostat i understand
The heater core by pass i don't,what does that prove ?

The shop says - intake manifold hose.

A hose causing overheating,explain that one.

The finally question
What is your question? Did the repair shop
get lost and ask you for help?

SOURCE: 1999 mercury villager is overheating, ive changed

Have it tested for combustion gases in the cooling system. You could have a blown head gasket from all the overheating.

Testimonial: "ok i will do that i also noticed that the lower radiator hose is not getting hot, could that be caused by the combustion gases?"

About the only thing left is the water pump.

We replaced the water pump, thermostat yesterday , still have a overheating problem. Acts like an air lock in the system. bled everthing and still overheating.

If you get a constant peculation of air bubbles out the radiator while your bleeding the system than you are likely another victim of the well know head gasket failures that occur on these engines (3.4 liter). All it takes is one overheating and they are done.

I would assume that you are sure the thermostat is working?

How do you bleed the radiator? on a 1999 merc villager

With all cars the radiator has to be bled.
In most cases it just involves filling the reservoir and radiator, and squeezing the hoses until all the air bubbles out that you can get, and then cycling the car by running it until hot, shutting it off and letting it cool, and repeating that a few times.
Each time it gets hot it will burp out some air and replace it with water from the reservoir.

But some cars trap too much air, so also have a valve on the engine that can be opened up. Cars with the engine far from the radiator even require having the car tilted on a lift, towards the filler. Adding a water hose connection T fitting to the heater hose is also always a good idea. Not only is it good for back flushing, but for bleeding as well.

1990 mercury cougar keeps overheating have replaced radiator and thermostat and problem is still happening. waterpump is not making a noise any suggestions Wayne

Get your radiator cap checked and if replacing use the one for a overflow tank. If the cap pressure was okay then you want to look at water circulation in the radiator. After the thermostat opens you should see flow inside the radiator. If it does not circulate the block is clogged or the water pump is bad.

Finally, if you have an electric cooling fan there are relays and some have two fan speeds. Autozone may be able to diagnose your problem.

you have air trapped in the system. very hard to "BURP AIR"

park uphill on ramps if possible. With cold engine, leave radiator cap loose and fill radiator and reservoir. run engine until thermostat opens. squeeze upper radiator hose with hand. SHould be hot. Have heater on hot and blower on too. Repeat as necessary. May take several attempts.

Go here and we can help if that does not work

Heat blows cold when car is idling

You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

No heat

if you replaced the thermostat, you have an air bubble trapped in the engine. So, you don't have any coolant running through the heater core, therefore no heat.
sometimes hard to "burp" air bubble. Try this. Park park facing uphill and jack up front of car too. You want to get radiator opening higher than top of engine. Then remvoe radiator cap (cold engine), fill radiator, then fill coolant reservoir to full point. Install radiator cap but leave it loose so air can escape. Start engine until upper radiator hose going into radiator is hot. This should burp air. Repeat a few times while adding coolant mix (50/50 antifreeze) to keep radiator full. Be careful not to remove radiator cap when engine is hot.
lwt us know how ou make out. There is a more complicated procedure but you need tools and knowledge of where air bleed is on top of engine
