A car can overheat while idling if there is not enough coolant in the radiator or there is a malfunctioning fan, radiator or fan belt. Additionally, some cars have a fan clutch that may cause overheating.Know More
To check a car's coolant levels, allow the car to cool and open the radiator cap. Water should be visible at the top of the radiator. If water is not visible, add the appropriate coolant, typically antifreeze and water, to the radiator and replace the cap. Start the vehicle, and let it idle for several minutes to determine if the problem has been resolved.
If the coolant levels are correct, the problem may be a malfunctioning radiator, cooling fan or fan belt. A radiator leak is typically visible from the bottom of the car. Turn the air conditioning off if necessary, fill the radiator and check under the car for water leaks. Replace the radiator if leaks are present.
The fan and fan belt are also part of the cooling system. Refer to the owner's manual to find out the number and placement of the cooling fans. To determine whether the fan is working properly, turn on the air conditioning and check the engine compartment. If the fan is not turning, the issue may be the fan belt or fan clutch. Replace the faulty part to repair the cooling fan.Learn more about Engine
When a car squeaks during acceleration, it is typically an indication that the fan belt has become loose or worn. A car's fan belt loosens over time and starts squeaking when the bottom section, which has rubber teeth, begins to drag.Full Answer >
Some of the reasons that a car can stall when accelerating are a defective throttle position sensor, low fuel pressure and spark plugs that need to be replaced. When the "Check engine" light is on, a code scanner can be used to identify the cause more accurately.Full Answer >
A crankshaft on a car is one of the major components of the engine that powers the drivewheels. The pistons create power in the engine using an up and down, or reciprocating, motion, and the crankshaft converts this to a circular or rotational motion.Full Answer >
A car powered by an internal combustion engine moves by transmitting the engine's rotational movement to the wheels via the transmission, driveshaft and differential. Front-wheel drive cars do not require a driveshaft, but rear-wheel drive and four-wheel drive cars use driveshafts to transmit power to the rear wheels.Full Answer >
