A hole.
too much water added the overflow is designed to let out water.onece the radiator reaches the required pressure,the excess water is exhausted thru the overflow
Probably the thermostat is sticking.
NO it will not, It will cause other problems like stoping up the heater core and radiator. You MUST replace the intake gaskets.
THE CAUSE COULD BE A STUCK THERMOSTAT , OR A BLOWN HEAD GASKET, OR A LEAK IN THE INTAKE MANIFOLD OR INTAKE MANIFLOD GASKET. A CRACK IN THE INTAKE MANIFOLD IS VERY COMMON.. NORTY
The Sensor is dirty cause of a lower intake leak it allows oil to get in the radiator. lower intake leaks roughly cost $800 to fix at a normal mechanic shop hope this helps.
Anything toxic can cause ground water contamination if poured on the ground.
intake gasket, leaking radiator and radiator cap, leaking heater core,, air in the sytem that needs to be bleed by the bleed screws,,,but most of all on all these cars with the 3.8 or 3.4 are bad about intake gaskets,,hope this helps
Cracked head or leaking gasket. The suction is created on the downward stroke of piston during intake stroke.
I don't think a blown intake gasket would cause it to overheat, Most causes of overheating are: thermostat stuck in closed position; faulty water pump; broken fan blades; loose belt; clogged radiator; radiator cap not holding pressure; blown head gasket; low or no coolant; leaking hoses.
Yes, a restricted or leaking radiator can cause the engine to overheat.
Radiator cap
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.
