What would cause pressure in the radiator besides thermostatalready replaced head gasket?
radiator cap
What is the Cause of radiator cap breaking?
The spring on the bottom of a radiator cap will cause it to fail. If the spring does not work properly it can lead to pressure escaping from the radiator which can overheat the vehicle.
Will a bad radiator cap cause excessive pressure that will cause the coolant to boil off instead of circulating through the engine?
No. Excessive pressure will not cause the water to boil off quickley. It will cause the radiaor hose or other components to burst causing loss of coolant. A bad radiator cap can cause high or low pressure; low pressure will cause the coolant to boil at a lower temperature.
How would a radiator cap cause a leak?
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
Can a blown head gasket cause a radiator to explode?
Most definitely. A blown head gasket can cause the temperature to rise and put back pressure into the radiator, therefore possibly causing the radiator hoses to blow, or even bursting the radiator.
What would cause your radiator cap to blow off?
the radiator cap is a pressure regulating device if it is blocked for some reason the pressure in the cooling system could blow it off
Can radiator cap cause overheat?
Yes, if it is not holding pressure or is allowing a coolant leak.
Troubleshooting differs from diagnosis in that .?
troubleshooting focuses on how to fix the problem
What cause radiator hose to ge hard under pressure?
Internal pressure of the cooling system which is normally around 17 psi.
Why would steam be coming out from the radiator cap?
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
What can cause white smoke from radiator?
Steam? Leak? overheating due to low coolant? Back pressure due to a bad thermostat? Defective radiator cap? have system pressure tested to determine location of leak
What would cause gurgling on a 1997 Chevy Tahoe?
The pressure from the radiator is pushing out through the overflow canister. Probably solved with new radiator cap but could be an indication of head gasket problems if pressure gets too high.
