How to Fill and Flush Your Truck Radiator How to Fill and Flush Your Truck Radiator
A truck radiator should be flushed periodically and filled with new radiator fluid. This process will allow your truck's radiator to run properly, delivering the necessary coolant in order to prevent your truck from overheating. A truck engine that overheats on a regular or frequent basis can cause damage to the engine, which could lead to engine failure and a potentially expensive repair bill.
In order to flush and fill your radiator you need some tools and follow these steps in order to accomplish this task. This type of project is one that most every truck owner can accomplish on their own without having to take the vehicle to a repair shop for the assistance of a qualified mechanic. It should be noted that the process for flushing and filling your truck radiator is not different from the process used on a passenger vehicle and since most trucks used on a personal, non-commercial basis are in fact passenger vehicles, this should give you comfort that the process is not that difficult.
Step 1: Park the Truck Wear You Can Work Easily
Move the truck into an area at your home that will allow you the easiest access to the radiator. You want to have enough room available in order to remove the radiator and drain it without bumping into any walls or another vehicle that you may own. The best place to work would be in the driveway of your home. Be sure to place a large drop cloth or cardboard on the ground in order to catch any spills that may result as you remove the radiator from the truck.
Step 2: Locate the Truck's Radiator
You will need to locate the radiator in your truck in order to remove it for draining. In most every truck model that is made, regardless of type, make or year, the radiator is going to be positioned at or near the front of the truck. This will make it easier for you to find it and remove it.
Step 3: Remove the Truck's Radiator
Use a screwdriver in order to disconnect all of the hoses that are connected to the radiator. With the radiator hoses removes, loosen the bolts that are holding the radiator in place. With the radiator loose, carefully lift up and away from the frame of the truck. You can take the radiator to a separate area in order to open the drain plug and empty out the radiator before you flush it.
Use the ratchet to loosen the drain plug at the bottom of the radiator. Hold the radiator over the drain bucket and empty the contents. With the radiator drained, run a garden hose through the top of the radiator by opening the radiator cap. Run the water through the radiator until the discharge going into the bucket is clear, indicating removal of all of the dirt and grime.
Step 4: Reattach the Radiator and Fill
Close the drain plus and place the radiator back into the truck, attaching the bolts and radiator hoses. With the radiator back in place, fill the radiator with the appropriate mixture of radiator fluid or coolant and water.
