You will need:
1 Drop Cloth
2 Five Gallon Buckets
Large Adjustable Crescent Wrench
2 LP132 Lube Filters ( with new gaskets)
22 Quarts ( 5.5 gallons) of 30W or 30 SAE motor oil.
Lay out your drop cloth under your work area. With out any leaks in the engines you are about to release ( in two different stages) a total of 5.5 gallons of used oil. Depending on where you are working you will want to cover to ground below.
Put on you gloves and headlamp and get under the truck with the adjustable crescent wrench and two five gallon buckets.
Locate the drain plugs, two large bolt heads at the front and the back of the bottom of the engine (see photos)
place 1 bucket under the plug, loosen bolt until almost out and then finish by hand ( so the bolt doesn't fall into the bucket, because then you are about top have to fish that out form all the oil it is about to fill up with)
Leve that bucket to catch excess and then repeat process with the from plug.
Allow adequate time for all old oil to drain from the engine.
