    Run the engine until it is hot, not overheated, then shut it down and run cold water over the radiator, slowly open the cap and top of the coolant.

Yes this would cause the car to oveheat. DO NOT drive this car if it is overheating!! you will damage the engine very quickly.

    Have the cooling system pressure tested (requires a special tool) to determine where the coolant is leaking out from the engine.

    im sure its not loosing coolant. i changed a few hoses that were qusetenable. air keeps bubeling into over flow tank. can this air stuck inside cause the heat to stop working and then also make the engine get hot?

    You must bleed the air out of the cooling system on this model and engine. Here is how you do that.
    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 possible, 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 system.

    Remember do not overheat this engine!! I can't emphasize that to much on the caddy engines.

I have a 2000 deville dts that was doing
the same thing.The problem was the mode door actuator located behind and to the left of the glove box. There is only one there and it is about a 3"x5" black box. Disconnect the electrical connector, two 5.5 mm screws, a little wiggling and pulling straight out, and it's out.

2002 cadi deville the heat will come on when i hit a bump,ever so often;changed the thermostat and flushed the radiator;is there a air release vavle to let the air out of the system and were is it located


typically, you can remove some pockets of air in the system by setting the interior heat setting to maximum. This allows the coolant in the heater matrix and pipes, to circulate out, along with any pockets of air.

But I'm not sure air pockets are your problem. It especially sounds strange than you mention the heat coming on after a bump.
Are you sure your interior blower motor is working? Have you checked to see if there is air coming out from your blower vents in and under the dash?
If not, then please check your blower motor's connections and operation. If it is only working after a bump, then it could have suffered wear to the inner motor. In which case it may require replacement.

1992 Cadillac Deville blowing air but not heating?


There is a damper (basically a door) in the heater unit that is probably not being actuated. This damper allows the air from the blower to be sent over the hot heater core and thus warming the car interior. This damper might be either vacuum controlled or electrically controlled. My 1992 Blazer had vacuum lines that went to it. It could be that you have the vacuum lines loose under the dash. Look for loose hoses or connectors and see if you see an obvious place they might plug into.

Front brakes wont fully release


There's air in the hydraulic system - bleed the brakelines to get rid of any air in the system. When braking air get compressed to a tiny pocket, when releasing it expansed and cause the brakes to still hang on to the disk for a while.

Can a worn coolant reservoir cap cause a 2002 Cadillac to run hot?


I would check to see if the hose has fallen off the reservior container, if this occurs the
engine will vent coolant and get an air pocket and run hot. (This happened recently on
my S-10 pickup) The hose had fallen behind the battery and did not appear out of place.
I would also suspect the thermostat sticking as a secondary culprit if no air pocket exists
in the engine block. The reservior tank holds liquid to be drawn back into the engine as
it heats up and cools down and should never be completely empty. Hope this is helpful.

It doesnt do it when cold and starts fine it only seems to be when its been run for a bit


You left out the problem. All I know is something happens when warm or hot. All I can tell you is parts heat up and when they get old they fail to work properly. Sensors going bad will heat up and spike voltage to ECM and cause a stall. Overheating check your radiator for leaks or low coolant. Fill accordingly and run a few minutes with cap on loose to remove air. Air pockets in cooling lines causes car to overheat.

No heat


sounds like you have air in the system. when major cooling system components are replaced and not properly bled, air pockets form causing you to loose your heat function.
