Best Answer

* A water pump failure could cause this.

* If the pump is turning backwards due to the serpentine belt being improperly installed

* but it sounds like a bad or mis-installed head gasket would be the most probable.

Another suspect: thermostat installed backwards

Not very likely - the Windstar was significantly redesigned in 1999, and the dimensions of the vehicle were changed.

Check the grille on the front of the radiator and be sure that it is clean of all mud and debris otherwise the radiator is not able to pull air through to cool the water. You can clean that grille by removing the radiator from the truck and lightly pressure washing it.

You have changed the thermostat but your 1997 ford contour is still overheating What could the problem be?

Radiator plugged or restricted? Cooling system airbound? Water pump not circulating coolant? Radiator cap defective? Radiator hoses collapsing under pressure? Defective gauge/cooling temperature sensor?

When the car is at around 225degrees should the the upper radiator hose be hard to squeeze its a new radiator a new water pump a new thermostat and all the hoses has been changed?

yes the air/fluid gets hot and expands. The pressure within the cooling system should be what ever the radiator cap is set for, usually 15 to 16 psi. If it is more than that, replace the radiator cap.

No they are not the same - the engines changed from 98 to 99.

Your Toyota Previa 2.4 still overheats thermostat changed radiator ok water pump replaced what could be wrong?

If the radiator or reservoir cap is bad it could cause overheating because the system will not build up the proper pressure. Also the fan clutch could be worn out which would keep the fan from spinning fast enough to cool the radiator.

Why would a 1998 ford windstar gl cut off when driving?

I would look at the ignition or fuel pump. most of the time it is the fuel pump. on a 98 if the pump has not been changed the old one will not produce the right pressure, it will be to low.

Your car radiator cap press 15 psi what will happened if it changed to 18 psi?

The coolant system is designed to operate at a specific pressure. Switching to an 18psi cap will put too much pressure on the system and could cause part failures, like blown hoses.

Rocks that have changed as a result of heat and pressure?
