I just have a 1993 chevy cavalier it was over heating and boiling water back up out of the water coolant tank.

Question

So I had my father to put a new thermostat and water pump in it and I am running 50/50 antifreeze in it now....But I drove my car home today snd after putting the new pump and thermostat in it is still overheating and boiling water out of the water coolant tank. SOME ONE HELP PLEASE..

Answer 1

Take your car to a place that does radiator repair so they can open up the radiator and unclog the small valves inside. It seems the water(coolant) isn't circulating and with the heat,it's building up pressure.

Answer 2

Boiling water into the tank? Not a good sign. Without a proper inspection it's hard to be sure, but it sounds like you have a problem with the head gaskets at the very least. It may turn into much more once the vehicle is apart. Another sign is when you don't have heat when you turn the heat on.

Answer 3

I have a Buick Century of the same year, and my car was doing the same thing. On my car, it was discovered that the fan casing behind the radiator cracked from having a jack placed there and jammed the fan, which helps cool down the radiator fluid. Once the fan motor was replaced and a new fan casing installed, the problem has never resurfaced. Good luck to you. =)

Answer 4

Head gasket is maximum possibly to be the subject. while water or coolant would not look below your motor vehicle is provided that's leaking in to you heads. See in case you notice fluid popping out of your tail pipe while your motor vehicle in on. Have it appeared at ASAP because of the fact the longer you wait the costlier it's going to be.
