Instructions:
1. Open the hood of your truck and locate the radiator cap. It is usually a black or blue plastic cap located near the top of the radiator.
2. Remove the radiator cap carefully, allowing any pressure to escape slowly.
3. Remove the skid plate underneath the truck using the wrench.
4. Locate the drain plug on the bottom of the radiator. It is usually a small, plastic plug located near the bottom of the radiator.
5. Place the 5-gallon bucket underneath the drain plug.
6. Gently open the drain plug using a wrench. Be careful not to drop the plug into the bucket.
7. Allow the old coolant to drain out of the radiator into the bucket.
8. Once the radiator is empty, close the drain plug and remove the bucket.
9. Add a radiator flush to the radiator following the directions on the product label.
10. Fill the radiator with clean water using a garden hose.
11. Start the engine and let it run for a few minutes to circulate the radiator flush.
12. Turn off the engine and allow the radiator flush to sit for the amount of time specified on the product label.
13. Drain the radiator flush and clean water out of the radiator by repeating steps 5-7.
Now that the radiator is flushed, it can be refilled with new coolant. To do this:
1. Add the correct amount of coolant to the radiator following the directions in your owner's manual.
2. Replace the radiator cap and make sure it is tightened securely.
3. Start the engine and let it run for a few minutes to circulate the new coolant.
Your radiator is now flushed and filled with new coolant.
