Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hi, my name is ***** ***** I will assist you. When it overheated, did the car shut off at that point or did you cut it off yourself?
did it overheat the next day when you drove it?
The reason I am asking this is because it sounds like you have low compression as a result of the overheat...this can cause exactly what you are describing and unfortunately usually results in engine replacement.
ok, I gotcha. So, unfortunately it sounds like you have overheated the engine to the point of no return...but there are a few tests that can be done to verify this. Are you able to get your hands on an engine compression gauge? They usually will rent them at a parts store.
Awesome...If you don't know the procedure, you will simply remove the spark plugs and install the gauge in one cylinder at a time. Let the motor spin over approx. 7 times and then read your pressure. Record it three different times for each cylinder. Then, go back and do each one again after adding a teaspoon of oil in each cylinder and record those readings in the same way. If the compression significantly jumps after adding oil, you have a problem with the piston rings. If the compression does not jump, then you have an issue with the head gasket/valves. I would expect that the head gasket is ruptured and possibly cracked head. I hope that this is not the case, and good luck!
