Where is the air bleed screw on the coolant lines for this car. I replaced the water pump and thermostat and now the stupid thing overheats all the time. Where is the bleeder screw location for it????
Please help
I had the same problem with my 2001 Cadillac Deville, like you I had replaced literally everything thermostat, water pump, radiator, temperature sensor, reservoir and cap, hoses etc....I didnt have any leakage. I was told I had air in my coolant system. After a lot of research and running across the right mechanic I was able to locate the bleeder and remove the air from my lines. No problem since. The bleeder is located on yhe left side of the radiator on the crossover, mines was sideways..Hope this helps someone before they spend money for new head gasket problems..Try this it helped me....

The engine coolant temperature sensor is located on the driver side of the engine near the rear of the engine compartment

Perform a liquid block test (with the bottle of fluid over the radiator mouth.) If the blue liquid turns yellow or clear, you have hydrocarbons entering the cooling system (usually via head gskt.) If not, you have ruled out a costly repair.
Sounds like it overheats pretty easily, without t-stat! This block testing liquid is cheap, and will verify a suspected leaking head gasket without lengthy diagnosis. Hope it's better news, but good luck!

I have not tried myself but see if the link below will work for your case. It is not the same model as you have but most vehicles have the same components for the non electronic parts. http://www.2carpros.com/forum/1988-dodge-dakota--bleding-air-out-of-clutch-master-cylinder-vt248517.html

Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With
the engine idling,pull the purge line from the tank,if there is no
coolant flow from this small hose,it is blocked and this will cause
overheating.If the hose is clear, check for blockage at the nipple on the tank.
The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml , if it still overheats then you need to have the head gaskets checked with a gas analyzer for hydrocarbons present in the radiator or recovery tank
