If the water pump on your Ford Windstar becomes damaged your engine will no longer be able to cool down. This is because the engine will be unable to receive the coolant required from the radiator. When this occurs you should replace your old water pump with a new one. Head to your auto store to pick up a replacement, making sure you get the correct size and model needed for your Ford Windstar.

The thermostat in the Chevy Cobalt is located inside the water inlet housing, which bolts onto the bottom of the water pump. Because the housing is located low on the motor, you must remove the coolant from the radiator before you can proceed with removing the defective thermostat. This makes the job somewhat harder, but the task is not overly difficult to complete.

A GMC trouble code of P0466 gives the mechanic or owner a couple of ideas as to the cause of the code. The P0466 is a generic code, one of the many on-board diagnostics (OBD)-II codes available.

When installing an auxiliary fan or simply wiring the factory fan so that the driver can manually turn the fan on and off, make sure the fan is turning in the right direction. If the fan is not turning in the right direction, air will be blown away from the radiator, and will not help to cool the radiator. To check which way the air goes, just put your hand in front of the fan to make sure the air is blowing through the radiator. The fan will turn in either direction depending on which of the two wires the power is supplied to. There are two methods to wire the relay, one with manual control and one with automated control.
