Can you tell me what engine you have?
Thank you. You have one of two 2.7 or a 3.5. Your coolant factory color is orange. 50 50 mix of water and coolant.
sorry it is 3.5 and the coolant case has always been the white despite the coolant color.
Why would the coolant come out and pour on to the driveway and street and now it cannot be duplicated. Can that happen?
One of a few reasons.
Engine runs hot due to low pressure on the cooling system.
1. leak a pressure test will show the leak. If not external then internal.
2. Radiator cap is faulty not holding pressure can be tested with a pressure gauge tool.
3 bad head gasket allowing pressure from a cylinder to leak into the cooling system over pressurizing the system.
How fast does it take for the coolant to spill out?
Do you hear the cooling fans running at anytime?
Ok thank you,
So, From cold in five minutes you have coolant leaking out of the reserve bottle?
You may just have a bad radiator cap.
What else have they told you??
They did all the above that you mentioned. How could you tell if the cap on the coolant was bad? Doesn't the cap loosen to allow the pressure out of the cap?
Here is information on testing the cap and tools. THe cap is to hold 18psi of pressure and should never allow pressure to be lost bellow that number.
CAUTION: Vehicles equipped with 2.4L engines use a different pressure cap than vehicles equipped with 2.7L engines. The pressure caps are NOT interchangeable. Verify proper pressure cap part number.
Dip the pressure cap in water. Clean any deposits off the vent valve or its seat and apply cap to end of the Pressure Cap Test Adaptor that is included with the Cooling System Tester 7700. Working the plunger, bring the pressure to 104 kPa (15 psi) on the gauge. If the pressure cap fails to hold pressure of at least 97 kPa (14 psi), replace the pressure cap.
CAUTION: The Cooling System Tester Tool is very sensitive to small air leaks that will not cause cooling system problems. A pressure cap that does not have a history of coolant loss should not be replaced just because it leaks slowly when tested with this tool. Add water to the tool. Turn tool upside down and recheck pressure cap to confirm that cap is bad.
If the pressure cap tests properly while positioned on Cooling System Tester but will not hold pressure or vacuum when positioned on the filler neck. Inspect the filler neck and cap top gasket for irregularities that may prevent the cap from sealing properly.
Is the car at the dealer?
Is the cap not fully locked?
I can not believe a dealer will be unable to lock the cap.
Yes the car is at the dealer. No I am sorry the dealer had no problem with the lock. I meant when the car broke down I was observing the cap.
Right now the service manager is driving it home to duplicate the problem. I will get a call in the morning. Would you like me to contact you?
Sorry for the late reply. dinner.
It may be you have a radiator cap that is indeed bad. If the car was moving and began loosing coolant it can be an overheat issue or a loss of cooling system pressure.
Let me know how it works out. I know it is under warranty but I just want to make sure your car is fixed.
