Question:

Whats wrong here? 98 Cavalier z24 2.4L antifreeze/water pump?

Well I know the water pump is leaking and its leaking fast. So I put water in the coolant reservoir and when I drive it acts fine but then when I stop and idle the coolant tank starts too over flow and spits the water out everywhere. Car still being at reg temperature the coolant reservoir is steaming/smoking? I can't tell which. But there doesn't seem to be water in the oil??? What's going on? If the water pump is replaced will this stop?

Answer:

If you are loosing water due to a leak coming from your water pump the radiator can not hold pressure making the water over heat that is where the steam is coming from and as far as how long it will take you to replace the water pump time will tell if this is your first time it may take you 8 hours but like they say it is better to have tried than to have not tried at all.

Hi... There could be two problems here. First ,the thermostat is stuck open, second, a blown head gasket. Compression leaks out to the cooling system,increasing pressure ... So ,no it won't correct the situation.

Start where the obvious problem lies. Replace water pump AND thermostat AND radiator cap.
