My car just overheated on me. It was not spilling water through the radiator cap but a lot of air was whistling out of the water pump. Is that my answer? Thanks
Any water on the ground? Do you mean no water coming out of the actual cap, or going to the resevoir, or what? Check to make sure it's full, not empty. Run it again, and check the fluids. Also, you might want to fill it once it's cool and leave the cap off to see if it bubbles or not. If it bubbles pretty bad and spills out right away, you've got a bad gasket that's eating your water.
Turn the car off and reach under the neck of the waterpump. Behind the pulley, on the bottom. There should be a little hole, it's called the weep hole. If that is wet then it's your water pump.
The radiators usually leak from one of the end tanks, so look for that at the bottom corners of the radiator.
I found the damn problem. My thermostat housing is corroded and water was spilling from there. I knew that was gonna happen when I first saw at the junk yard. It was the only one I could fine. I need a new one. Any recs?
