Step 1 – Drain old coolant
To drain the old coolant, open the radiator cap, then place the drain pan under your radiator's drain plug. Loosen the drain plug with your fingers by turning it counter clock-wise. Let the coolant drain completely.
Step 2 – Fill with new coolant
Make sure the drain plug is closed on the bottom of the radiator, then fill the radiator with 50/50 coolant until it reaches the top.
Step 3 – Start truck, then refill
Start the truck and let it run for a few seconds, then check the coolant's level again. It will most likely be lower; add more coolant until it reaches the top.
