Ive had a similar problem with another car of mine. The solution was to run the car with the coolant cap open so the air could be pushed through the lines. Ideally you want to run with an open cap until your pump kicks in. This is the process you need to use when you replace a rad or drain all the lines. Don't be worried if you see coolant gushing out of the overflow. It takes about a minute then the overflow will level off and all the air bubbles will stop.
No
The engine coolant reservoir or the overflow bottle.
Remove the jug and wash it out with soap, water and a bottle brush.
The head gasket is blown.
I should have stated that the jug appeared halved internaly.
There is a sensor either in the coolant recovery jug or the radiator side tank that is defective.
there is no real radiator cap. On the left side of engine compartment there is a coolant jug. This where you would add coolant to radiator.
Replace radiator ASAP. And flush tranny fluid.
Many things can cause the car to overheat. 1. Low coolant caused by leaking hoses, water pump, intake manifold on v6 engine. 2. Bad headgasket on v6 engine causing coolant to overflow out of the reservoir jug. 3. Stuck thermostat. - TechJK ETC. -----------------------------------
The coolant add/overfill jug is on the left side of the motor when your looking at it. Add coolant up the closest line towards the top, and only when the engine is cold.
The engine coolant overflow reservoir is to the left side of the engine compartment. Checking levels, adding coolant, and coolant specifications are detailed and illustrated in the Owners Manual - See "Related Questions" below for more
while the engine is cold take the radiator cap off located under the hood in front of the motor. top this off with a coolant mixture of 50% coolant and 50% distilled water. do the same for the reservoir to your left. it is a white jug with a screw on cap beside the radiator. it will have a line on the jug about half way down. do not fill above this line.
