   My engine coolant keeps on overheating, I’ve tried changing the antifreeze tank out for a brand new one and it helped the issue for a while but I have to relieve the pressure myself which is a hazard.

When I go out roundabouts off a highway the engine overheats and makes the car go into a safe mode where it won’t go and I…

    My engine failed months ago, and my car has been sitting immobile ever since. My car stuttered while driving, and then turned off. As I started it back up and continued driving down the road, it was shaking very badly. I called my brother to come drive my car home and he pulled clear fluid out of my oil tank.
