Diagnostic Trouble Code (DTC): P0494 P0494 code definition If the PCM has detected a voltage reading that is too low from the electric cooling fan control circuit, the P0494 code will...
The purpose of the cooling fan relay is to pull air through the A/C condenser and the radiator. Most vehicles have two fans, one for the radiator and one for the...
The purpose of the cooling fan resistor is to remove heat from the engine’s coolant and from the A/C refrigerant. The resistor does this by drawing air through the radiator and...
The hose heater control valve opens and allows hot coolant from the engine to blow into the heater core. After the vehicle gets to the correct temperature, the thermostat...
The coolant recovery reservoir is both an expansion tank as well as a coolant recovery tank. In modern vehicles, the radiator has no cap so it has no upper tank for...
The coolant tube, or hose, carries coolant to and from the engine in your vehicle. First, the coolant tube removes the hot coolant from the engine and brings it to the radiator...
Diagnostic Trouble Code (DTC): P0495 P0495 code definition The P0495 code is stored when the PCM has detected a voltage reading that is too high from the electric cooling fan control...
Summer's heat, dust, and stop-and-go traffic will take their tolls on your vehicle. Follow these tips to ensure optimum wellness of your car: Air Conditioning: Have your air...
Flushing the cooling system is part of every vehicle's scheduled maintenance. This procedure is usually required every two to four years, depending on the vehicle. It is important...
In order to verify the leak you will need to have the cooling system pressure tested to see if it is just a hose or the radiator is leaking. This way you do not replace good parts. You may have...
Hello, thank you for writing in. While it is strange to think the thermostat can be located on the lower radiator hose, this is common practice for some manufactures. The concept works exactly the same. The coolant entering the radiator...
You have two cooling fans and both should be running when the a/c is turned on. If the fan on one side or the other does not come on then have the fan checked to see if the fan is...
If you have to keep adding coolant to the reservoir then you have a leak somewhere and would need to have the cooling system pressure tested to locate the leak. If there is no leak externally then you may have...
The only way to try and flush out all the sand is to drain the cooling system and flush out with fresh water until the system is cleaned out the best as possible. Even after this you will need to...
Hello, thank you for writing in. There is not a bleeder valve on the cooling system, as the newer models are designed to "self bleed". Your owner's manual can confirm this, and give you more information on how your specific...
The radiator fan is computer controlled and you would need to have the computer scanned to see if the fan is having a computer or sensor problem or the fan relay is stuck in the on position. The fan has...
The fan bolts would not loosen on their own and may not have been tightened up all the way. I have seen the fan blades come off and damage the radiator but never a fan bolts coming loose. They were...
You need to open the hood and with a/c on and engine running see if the cooling fans are coming on. If not then system will need additional diagnosis to see if fan motors are bad or the control system...
Hi Marcel. Thanks for submitting your question today. If you found coolant on top of the motor, then it is more than likely that the coolant inlet hose attached to the top & side of the motor either has a...
You may need to replace the bent fan or it will be out of balance and damage other components. The belt will need to be inspected to see why it came off. You may have a seized component like the...
You're probably low on coolant. Filling the reservoir doesn't really do the trick for filling the cooling system. There is probably air trapped in the cooling system that needs to be bled out. You may be able to do it...
You have a leaking rear a/c heater system core or hose for the rear unit. You will need to keep the rear heater turned off and keep coolant in the engine full to prevent overheating the engine. Have the cooling...
There are two ways your thermostat can fail. Either it is sticking open, and the car is not coming up to temperature, or it is sticking shut and the engine is running too hot. Either one can cause problems, but...
You should have the cooling system checked for proper operation. Your cooling fan or its control circuit may have been damaged in the accident. It may not b coming on and cooling the engine.
If you have been running low on coolant and been adding water instead of coolant then you do not know the coolant level of protection for anti-boil or anti-freeze and should replace all the coolant fluid in the car. If...
You should disconnect both hoses from the heater core and connect the two hoses together with a piece of pipe or cut off a piece of the heater core pipe to use to connect the two hoses together.
If your truck has automatic climate control, what you heard could have been the air diverter doors moving back to their default position. We used to joke about some cars sounding like there was a little guy inside the dashboard...
I can't help but think that there is a little more back-story here. But I presume you bypassed the heater core because you had a leak inside the car. That's something you can do if you don't need heat of...
Without more specifics on the location of the coolant leak I would suggest having the cooling system pressure tested to locate the leak. You may have a water pump starting to leak. This will get worse and may start to...
