How do you bleed or burp the cooling system in a Ford Taurus - Mercury Sable?

Answer 1

NEVER ever think of releasing a radiator - coolant cap when the engine is hot, or even warm!!!

Burping: In order to what is sometimes referred to as 'burping' the cooling system - getting a big air bubble out of the closed cooling system, you will actually need to have the car running with the cap off.

1. During the initial fill, fill the coolant reservoir bottle to the top of the cold fill range.
2. Set the temperature blend selector to the full warm position and the fan motor control to high for the front and rear heaters
3. Start the vehicle with the reservoir cap off and allow to idle until the thermostat opens

   NOTE: the coolant level will drop quite a bit when the thermostat opens - that's most of the air bubble in the system being driven to the top of radiator and escaping. Without the air, there's more room for coolant.

4. Top off the coolant in the reservoir bottle to the top of the cold fill range,
5. Install and tighten the reservoir cap.
6. Increase the engine rpms to 3,000 for 15 seconds, and then return to idle for one minute.
7. Repeat the previous step four times or until heat is coming from the rear unit while the vehicle is idling.
8. Allow the vehicle to cool and top off the coolant in the reservoir to the cold fill range.

Note: if you find the heater going cool or cold when idling, that's a good indicator you might have to burp the system again. Equally likely just adding more coolant to the overflow reservoir will suffice too.

Did I mention to NEVER ever think of releasing a radiator cap when the engine is hot, or even warm? !!!

AnswerEither park the vehicle on a steep incline going up hill, or jack up the front of the car. Remove the radiator cap on a cold engine and start the car with the heater set to hot. Watch for escaping air bubbles from the radiator, and keep it full of coolant. Once you see no more air bubbles escaping, it is good to go.
A commercially available universal vacuum type radiator fill tool will do the job in 1 minute or less unless you have a coolant leak.

Failing that, try letting the engine idle for a few minutes, then top it off.
Make sure car is cold remove the radiator cap let it run ,air will escape , do not attempt if car is warm , hot coolant might overflow !

Pick it up. Rest it on your shoulder and pat it on it's back.
