Cooling System

If you have a check engine light that is still on then you may need to have the computer scanned to make sure that there was no other codes or damaged from the overheating situation you had. You may need...

You would need to have the cooling fan relays checked to see if the relays are sending power to the fan motor. Also turn on the a/c to see if the a/c fan works since you have two fans one...

If you have sensors in the upper and lower hoses then I suggest checking to make sure you can remove them and cut the new hose? Otherwise you will need to get factory hose with sensors installed in them. The...

You may be developing a leak in the heater core. Your truck is about the right age. The heater core lives in the heat exchanger with the air conditioner evaporator so anything that happens in there will come out of...

To properly fill your cooling system, you need to start with the engine cold. With the engine off, fill the radiator slowly until the level is about 1"below the neck. Leave the cap off and with the car in park...

To begin with: you don't want to put straight water into your cooling system. You need to use a 50% mixture of water and anti freeze. You put it in at the radiator cap. Start with the engine cold and...

You need to check to make sure the condenser is not blocked in the front and that the fans are coming on when the a/c is on. The system may work okay in cooler weather if fan is not working...

In the old days, if the water pump was turning, it was working. But many modern cars have plastic impellers in the water pump and they can lose their grip on the shaft when they get old. It's hard to...

Wow! You'd better check the oil too! Driving the car this way is about the same as taking it out on the racetrack for about an hour. The racetrack always brings out any weakness that a car has so If...

Hello, thank you for writing in. If you did not get all of the oil out of the radiator before you started the vehicle, that oil is now contaminating the thermostat, water pump, and the engine cooling pockets. Even with...

This kind of behavior may mean that you are low on coolant. Normally the tip of the temp sensor is submerged in coolant. When the coolant is low, there may be an air pocket around the sensor that allows it...

Going by your description and the age of the car, I'm going to guess you have a problem with your water pump. The water pump has a rotating seal that often doesn't leak unless the engine is running. If your...

If the car was out of coolant, and shut off because it was overheated, then there is a good chance that there was some engine damage. But don't panic yet, the codes and leaks you have might be separate issues...

You probably have a leak, and the first place I would look is the radiator. Most likely you will see evidence of a leak at either of the two bottom corners. But don't stop there. Your car has a pretty...

The green fluid is probably coolant and the smoke is probably steam. You may have a serious coolant leak that is causing your car to overheat. If the car was driven very far while overheating, it may have caused some...

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...

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. The vehicle goes into "limp mode", or your model's version of, when it is at risk of becoming damaged. This is a good thing, and it will protect your engine from having worse issues...

If you have to keep adding coolant and the engine uses it and have to add more everyday then you should have the system pressure tested to see if there are any external leaks. If there is none then you...
