There should be bleeder valves either on the thermostat housing or by waterpump, just loosen them up start car and let it come up to temp. or until cooling fans come on, and watch them, when all air bubbles are gone and just coolant comming out, just close them back up and thats it. Now if there is no bleeders, just leave radiator cap loose on first notch and do same procedure stay back as it can be messey, when it looks like its all burped out shut off car let cool down and top off radiator and that should be it. Just watch your temp. guage as you do this as you don't want it to get real hot.

Low heater air temperature, which gets even cooler with increased fan speed.


could be your temostat, the water pump, blend door or motor, try the termostat first and then see what happens. try to bleed the cooling sistem too. maybe air in the sistem.

I have a 1994 Sedan Deville that cranks longer then it should on first start ever morning. It starts good the rest of the time. 4.9 liter V8


fuel pressure is probably bleeding off when it sets for a period. it probably is bleeding off into the return line if you see no leaks.turn the key on for 30 seconds then off before starting. if you dont like this then you can replace all of the fuel line o-rings in the system and pressure regulator/fuel rail assembly

1996 Cadillac Sedan Deville that overheats only when idling


The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,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.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.

check the master cylinder. It may need to be replaced.. When replacing, make sure to bench bleed it as not doing so would void the warranty.
