Fan Shroud Assembly Replacement Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes. 1 With the engine off and cold, open the hood and locate the fan shroud assembly bolted to the radiator. Photo may not be specific to your vehicle 2 Inspect the fan shroud assembly for cracks, damage, or missing sections. 3 Remove the fan shroud assembly mounting bolts to the radiator. Disconnect the wiring harness. 4 Remove the fan shroud assembly from the engine compartment. 5 Install a new fan shroud assembly in the engine compartment. 6 Tighten the shroud assembly to radiator mounting bolts. Reconnect the wiring harness. 7 Start the vehicle and idle until warm. Verify that the cooling fans operate.

Fan Shroud Replacement Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes. 1 With the engine off and cold, open the hood and locate the fan shroud bolted to the radiator. 2 Inspect both the upper and lower fan shrouds for cracks, damage, or missing sections. 3 Gain access to the upper fan shroud mounting bolts. Photo may not be specific to your vehicle 4 Unbolt the upper fan shroud from the radiator. 5 Disconnect the upper fan shroud from the lower fan shroud by removing the tabs. Remove the upper fan shroud. 6 Gain access to the lower fan shroud mounting bolts from under the vehicle. 7 Unbolt the lower fan shroud from the radiator and remove from the engine compartment. 8 Install the new lower fan shroud in the engine compartment. 9 Tighten the lower fan shroud mounting bolts. 10 Install the new u...

Fan Clutch Working Of Fan Clutch System In Car Helpful Information A clutch fan can fail one of two ways, it can either be locking the fan to the clutch causing poor mileage and a whirring sound, (like an airplane is taking off.) Or the silicone grease can leak out causing the fan clutch not to lock up, allowing the fan to "freewheel", failing to pull air through the radiator, this failure usually is followed by the engine overheating. The clutch fan is utilized at slower speeds while air movement is diminished. Basic Checks (Engine "OFF".) Inspect the fan clutch for leakage from the front or rear of the unit, input shaft and temperature controlled expansion spring. If leakage is observed, the fan clutch has failed. Next, grasp the fan blade and turn it, the fan blade should free wheel with some resistance. If the blade spins with no resistance, or doesn't spin at all, the clutch has failed. History A clutch fan was developed in the late 1960...

Cooling Fans Working Of Automotive Cooling Fans Helpful Information The engine cooling fan is designed to move air through the radiator when the vehicle is at slower speeds or stopped. This air flow removes heat from the coolant created by the engine using the radiator as a conductor. An engine cooling fan is temperature controlled to only run when needed. All engines have a preferred operating temperature and need to warm up to operate at peak efficiency. Temperatures above normal, even for short periods of time can cause internal engine parts to fail. Occasionally the fan will be audible after the engine has been shut off, this is normal and is performed to lower engine temperature to acceptable levels. Usually, electric fans will activate shortly after the air conditioner is turned on, this is done to dissipate the extra heat produced in the condenser while the air conditioner is in operation. Engine cooling fans are temperature controlled to only run when neede...

Cooling System Working Of Vehicles Cooling System Helpful Information The engine's combustion chamber can reach temperatures of up over four thousand degrees Fahrenheit. About thirty percent of the fuel is converted into actual power, and the remaining seventy percent is developed into heat. A cooling system protects an engine from damage by transferring heat to the atmosphere by using the radiator. A correct operating temperature is critical for the proper function of the engine which is controlled by the thermostat. Car manufacturers have found that a 195° thermostat is optimum for efficiency. Below this threshold the catalytic converter will not work properly which will produce increased emissions. In the beginning, water was used for cooling systems, as it's the most efficient fluid to absorb and dissipate heat. The disadvantage of using water is that it freezes at a higher temperature and, boils at a lower temperature than coolant besides causing rust. Eventual...

How To Replace Radiator Fan Motor Tools and Supplies Needed Socket set Wrench set Replacement cooling fan Fluid catch basin Protective eyewear and gloves Hose clamp tool or channel locks Helpful Information A cooling fan helps move air through the radiator when the vehicle is stopped or moving slowly. An electric fan motor connected to a plastic fan blade located directly behind the radiator which is controlled by a coolant temperature sensor. This engine temperature information is utilized by the computer which signals the control relay to send power to the cooling fan. When the air conditioner is used, the cooling fan automatically activates to remove heat from the condenser regardless of engine temperature. To inspect a cooling fan start with ignition key "OFF". By hand, spin the fan blade, it should "freewheel", if the fan motor does not spin or is hard to turn, it has failed and replacement is required. If the fan motor fails to activate el...
