check to see if your rad. fans come on when you turn on your a/c the compressor will not work if the do not come on
had a bad overflow tank that wouldn't hold pressure
No, it blows into low pressure areas. Air moves from areas of high pressure to low pressure.
Check the coolant level. Usually low coolant levels will cause this.
It can if it is stuck closed the engine overheats causing hot air ( steam ) to flow backwards to radiator cap which releases and blows steam pressure into recovery reservoir which starts blowing out the coolant in the reservoir making a puddle on ground.
It may have a leaking head gasket. Has the coolant level dropped and needed more antifreeze . If so check it with a pressure tester
Probably a blown head gasket
I will say you have a crack in your radiator and once up to pressure a seam blows out your water. I would check along the side.
Check your coolant level in the radiator as well as the overflow reservoir. Believe it or not, I had the same problem yesterday. This should fix your problem.
the system is probably out of coolant.
Possible causes: Insufficient/no coolant in the system; insufficient antifreeze in the coolant and the coolant is frozen: the water pump is faulty and is not circulating the coolant; the belt that drives the water pump is loose or missing.
Low coolant? Bad thermostat? Heater core airbound? Heater core restricted or plugged? Defective radiator cap not building sufficient pressure?
it blows up
