Villager 93 Overheat and no heat

[mshams]

I have a mercury villager 93 the heat was blowing cold air, but no overheat...
I took to a mechanic to fix the heat problem, he changed the thermostat.
and told me that I might need a backflush.....

Now in addition to the heat problem , he created for me a new one... overheat....?

Any suggestions?

radiater could be plugged?? him and the thermo he put in might be hotter 1 or in wrong but sounds like cracked head or head gasket leaking?? when car is set for awhile to cool off take radiater cap off see if it's circulating be carfull not to get burnt..if not circulating?? could be these things or plugged heater core..

Yes, not having the thermostat can cause problems.
Put the thermostat in a pan of water on the stove and measure the temperature of the water when it opens.
An old worn water pump can reduce coolant circulation and cause overheating.
Clogged heater core can prevent the heater from working.
Clogged radiator can cause the engine to overheat.
Debri in the fins of the radiator can restrict air flow and cause overheating.

Bleeding the air out of the heater cores is essential to prevent ridiculously pathetic heat and it's actually a little complicated. Look up Coolant Refill on this site: http://home.earthlink.net/~vqfaq/index.htm

One more tip, put the car on a very steep hill aiming upwards when you do this. Even after following all instructions to the letter, my rear heat blew nothing but cold and my front heat, well I'd probably have gotten more heat from a light bulb until I did this one thing, put the car on a steep hill aiming upwards. After that, like lightning, the bleeding procedure worked. Now it's hot as hell, front and back, like it should be. Also, I'm not sure the heating system bleed hose is necessary to hook up like it says in the directions. Mine sure didn't flow any coolant through it. But perhaps some air went through it, I don't know.

I just purchased a 2000 VILLAGER. First day it overheated. Took it to the lot where I purchased; they sent me to their mechanic, who found that the thermostat was installed UP-SIDE DOWN.
