Hello, I'm Chris.


Did it overheat bad or mildly?

Have you checked cylinder compression?

Did it die while driving?


Customer: replied 4 years ago.

It got pretty almost to the red . I stopped at a gas station . Then drove it one more mile . It started makeing a weird like wizzing noise and as soon as I made it to work it died . Im not very mechanically inclined . But I work with a bunch of mechanics . I have not checked cylinder compression .


Expert:  Chris (aka- Moose) replied 4 years ago.

If the car was driven long enough while to hot, that will result i n the head gaskets blowing out or the heads warping or major internal damage. This is where the test mentioned helps. If all 6 cylinders are not within 10% of each other and at or above 110 PSI then there is damage. You must have this test done and repair whats occurred then address the cause for overheating which can be a faulty fan or thermostat or water pump. Once running these things can be tested.


Thanks for pressing Accept, Chris

The next day I tried to start it up and it almost started .

You can keep trying to start the car if you want but if its got low compression, its not going to run.

Also i had a guy tell me my fuel pump was not putting much fuel out . That I needed a new one .
Expert:  Chris (aka- Moose) replied 4 years ago.

If you have low fuel pressure and the filter is fine your correct you will also need to replace the fuel pump and repair the cause and effects from it overheating.
