INSTRUCTIONS
First, remove the skid plate, if there is one installed on
your truck, by removing the 3 phillips head screws or 10mm socket.
Next, remove the 5 2" long bolts holding the ski plate into place using a 12mm socket. You’ll need to push the whole skid up and slide
it towards the driver side then release and it should come down.
Once the ski plate is removed, locate the oil filter and
bulk oil drain bolt
Using 14 mm socket loosen the oil drain bolt. Once the
oil is drained, tighten the bolt back into the hole. Be prepared, the oil comes out really fast, the oil catch pan may not do the trick, a 5 gallon bucket may be better than covering your driveway with oil.
Next use a 3/8” extension to loosen the oil filter drain bolt.
After draining all the oil out of the filter, wipe the
area off. Make sure you not to damage the gasket if
you plan on using it again. Then using a 65/67 mm 14 flute oil wrench and 3/8”
extension, twist the cap off.
Remove the old oil filter and
replace it with the new one. If you plan
to change the gasket, do it now. Twist the lower assembly that holds the filter
on taking care not to cross-thread. Then use your oil filter wrench to twist it
tight. Make sure to put your oil filter drain bolt back on (make sure the
gasket it on the lower assembly, then put the bolt on). Once everything is
tight, fill your engine up with the motor oil of your choice and check your oil
level on the dipstick.
Start your engine after filling and let it run for 2-3 minutes. Make
sure you oil pressure is in the operating range. Check for leaks.
Replace the skid plate. Above are the holes you’ll need to align the
hooks of the skid with. Make sure to have the plastic tabs of the front bumper
overlapping the skid, otherwise the skid won’t go back into place. Then using
the reverse process of removal, hand install the rear bolts into the skid,
working your way forward taking care not to cross-thread the bolts. Then
tighten the bolts. Finally tighten the screws; watch not to over tighten the
screws as it’ll strip the plastic holders on the skid (which can be replaced if
you do happen to strip them).
To reset your maintenance reminder system, you’ll need to turn
your key to on (but don’t start!) and make sure your odometer is on TRIP A.
Then key off. Press and hold the Odometer/Trip button. While holding down on
the button, key the ignition to on (Don’t start the engine!) The display panel
will count down from “------“ to “-“Continue pressing the button until the Trip
A is displayed. After this step, you are done.
