Ford Repair Questions? Ask a Mechanic for Answers ASAP
Have you been having trouble with the engine getting hot before this happened?
I bet it has a small coolant leak(antifreeze) and over time it lost enough to make the engine run hot and thats why it blew the cap off.
How much coolant did you have to add to the tank after replacing the cap?
It might be an air lock but it would have had to loose coolant first.
Is the gauge showing normal now?
Ok, that really helps me. Thanks.
Take it in and have the engine thermostat replaced. On these cars they tend to get corrosion built up on the t-stat and it will stick closed and cause too much pressure in the system. Its not an expensive repair at all and will take care of the problem!
Thats the whole problem though. When it gets a build up on the t-stat it will stick only sometimes and then work fine the rest of the time. I have seen this happen thousands of times over the last 36 years i have been doing this :-)
Bot***** *****ne is if you have the cooling system pressure tested for leaks and none are found, then i guarantee you the t-stat is sticking intermittently.
Please do. I feel real confident it needs replaced.
