a bad termastat
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
Low coolant?Cooling fan not working?Radiator air flow restricted?Radiator clogged?Water pump not working properly?Radiator cap defective?
There are several possible causes. 1. Check the fan. When the car is overheating, if the fan is spinning slow that means the clutch is defective. 2. When overheating, touch the upper and lower radiator hose. If upper is cool, replace the thermostat. 3. when overheating, upper hose is hot but lower isn't. That means the radiator is clogged. 4. upper and lower hose are both cool, water pump is defective.
Bad thermostat. It's usually a 5 dollar part but about 200 bucks in labor, unless you can do it yourself.
Either the radiator is blocked, or the thermostat is stuck closed, or the water pump has failed.or it just needs water.
Make sure the radiator fan is working when the AC is on.
A radiator fan is used to help cool the engine by blowing air across the radiator, which dissipates the heat generated by the engine. This prevents the engine from overheating during operation.
Fan belts are used to turn the fan in an automobile to cool off your radiator, or in a computer to pull cool air into the motor to keep it from overheating.
check the fins on your radiator they could be corroded and loose decreasing your radiator s ability to cool the engine or the thermostat could be defective also
The fan comes on and run continuously when the A/C is engaged which is normal. It will also come on to cool the coolant in the radiator to prevent the engine from overheating once the coolant reaches a predetermined temperature.
It is very common for the impeller of a VW to break apart. The result is engine overheating and no heat. Usually, the the radiator remains full unless severe overheating causes a boilover and consequent loss of coolant. Also expect that the engine becomes hot yet radiator and heater hoses remain cool. If this happens, replace the water pump. It is usually convenient to replace the timing belt at this time.
If the car is still overheating, there may be a clog in the radiator itself. Another possibility is the new water pump sucked sediment in from the radiator, causing it to have a malfunction. Lastly, the radiator fluid may be low or too old to properly cool the engine. Make sure the radiator fan is working.
