Check the temperature sensor
The cooling fans on a 99 Nissan Maxima will not come on if the coolant temperature sensor is defective. The fan only comes on when the temperature passes a threshold.
Where is the engine cooling fans sensor located on a 2000 Corvette ? Screwed in the driver side cyinder head just behind the Alternator. this is referred to as the temperature sensor. Hope this helps. Mike
The cooling fans on a 2002 Grand Am GT might not be working because of a problem with a fuse. There is also a temperature sensor in the engine that tells the fans when to come on. This sensor may be bad.
Your temperature sensor or a fuse is bad.
replace the cooling temperature sensor
Cooling fans are controlled by the computer based on input from temperature sensor. After the vehicle is shut down, if the temperature is still high, the computer will turn on the fans to cool the engine.
The sensor that controls the cooling fans is typically located near the engine's thermostat or in the radiator. This temperature sensor monitors the coolant temperature and signals the fan to activate when the engine reaches a certain temperature to prevent overheating. In some vehicles, it may also be integrated into the engine control unit (ECU) for more precise fan management.
On a 1996 Pontiac Grand Prix, the temperature sensor for the radiator cooling fans is typically located near the engine coolant outlet or in the engine block, often near the thermostat housing. This sensor monitors the engine temperature and signals the cooling fans to activate when the temperature reaches a certain threshold. It's important to consult the vehicle's service manual for the exact location and specifications, as there can be variations depending on the engine type.
On a 2001 Subaru Outback with a 2.5-liter engine, the temperature sensor for the cooling fans is typically located near the engine's coolant outlet, often in the cylinder head or the radiator. This sensor monitors the engine's temperature and signals the cooling fans to activate when necessary to regulate engine temperature. It's important to consult the vehicle's service manual for precise location details, as there can be variations based on specific models and configurations.
In a Pontiac Aztek, the cooling fans typically turn on when the engine reaches a certain temperature, usually around 226°F (108°C), to prevent overheating. They may also activate if the air conditioning system is engaged or if the vehicle is idling for an extended period. Additionally, fans may operate when the vehicle's temperature sensor detects high coolant temperature. Regular maintenance and monitoring are essential to ensure the cooling system functions properly.
There is no temperature control switch for the cooling fans. The PCM Power control module receives input from the temperature sensor on the water outlet housing. The PCM turns on the fans when the temperature reaches 210 degrees through the CCRM.
