My 2000 Sable started to overheat in heavy traffic/idle. Coolant bubbles over the resevoir cap during this.
Checked all my fuses (OK) but can't tell if the relays are bad.
Not sure if the fan is running or not BUT A/C runs cold and vent runs just as cold.
When I overheat, heat comes out of vents when manually cooling car down.
Recently had heater core tubing replaced.
Please help as I now work in the city and I am overheating more frequently.
Thanks

I let it run in park until temp gauge ran into the red. Fan behind the radiator never engaged. When I activated A/C, fan did not activate. Ideas?

check if your radiator fan connection is OK ... let the car idle for some time ..open the bonnet and stand close to it .. when the engine reaches a certain temperature the radiator fan should automatically tick on .. you will hear a click sound and a soft rumble of the fan coming on ..if it comes on then your radiator needs to be cleaned as it may be chocked up ..

also if it is a newer car, when you add water you have to bleed off the air in the coolant system, had the same thing happen to a 2003 Galant, Them vent screw should be on the coolant line close to the top of the coolant system. If you run the A/C make sure the fans are working. The thermostat send water through the heater core till a certain temp, them it opens so if its stuck closed i think it would stay running hot, and if its stuck open your heater will take a long time to heat up. So check you fans and water level. just cause the Radiator is full does not mean there in not any air in the system. that's what i would do.....

T-stat bad? Cooling fans not coming on over 200 degrees or with a/c on? temp sensor for fans bad?, relay bad, power to the fans and good ground? Radiator needs flushing? Lower air dam below the bumper missing, bent or damaged? Coolant is 50/50 mix of water and coolant?---check with a coolant tester from a parts store.

1. Thermostat going bad.
2. Radiator cooling fan not running properly. If it's run by an electric motor, check the temp sensor.
3. Water pump not circulating the coolant properly, might be going out.

Bad waterpump or bad thermostat. Waterpump can go for a couple of hundred and the thermostat should be under 100
