- Drain pan
Step 1 – Drain old coolant
To drain the old coolant, locate the drain valve on the bottom of the radiator, on the passenger side. Place the drain pan under the drain valve, then, with your hands, loosen the drain valve by turning it counterclockwise. Wait for the coolant to drain completely. Open the radiator's cap on top to allow it to breathe and drain faster.
Step 2 – Fill radiator with coolant
After the radiator has completely drained, and after you've tightened the drain valve, fill the radiator with new coolant until you see it reach the top.
Step 3 – Start truck and refill
After you start the truck and let it run for a minute, the coolant will get sucked into the engine. Turn the truck off, then add more coolant until it reaches the top.
