An oil change not only removes impurities, but it replaces depleted additives, as well as base oil that might have oxidized and broken down from heat. To get started, warm the engine and move the truck to a level spot.
TOOLS •60-75-quart drain container •Strap wrench •Long socket extension •Work gloves •Punch and hammer •Socket and torque wrench
3. Coat the gasket on the new manufacturer-spec filter with oil to prevent damage while tightening. With the filter in position, turn it backwards until threads engage properly, then turn forward gently until the gasket touches the block.
4. Use the strap wrench to turn the filter a three-quarter-turn farther. Wipe the drain plug clean and screw in with threads carefully aligned. Torque it to manufacturer specs with a socket and torque wrench.
5. Remove filler cap and install stated capacity of oil that meets all API and manufacturer-recommended specs.
6. Replace filler cap and start the engine. Once oil pressure builds up, check below for leaks. Shut down engine and allow oil to drain into the pan for a few minutes. Check dipstick to ensure oil level is correct.
