Replacing the skid plate on 07 Tahoe Z71

Remove belly "skid plate air dam" cover to inspect
Remove front bumper assembly to expose the guts Thread Washer fluid leaking and headlamp washers powering but no water

try the ground wire on the frame just in front of the rear bumper

The 2007 Tundra 5.7l engine doesn't have a spin on filter - it uses a replaceable paper cartridge within a permanent housing. Located under the skid plate on the front-left portion of the engine, the oil filter unit has two coolant hoses, a black plastic screw-in housing, and a large, metal, round screw with a 1/2" square fitting in the middle of it. The cartridge-type oil filter is in the housing.

If equipped with a skid plate, access is accomplished by removing the 5 skid plate bolts, allowing the plate to swing down on integrated hangars (with the front plastic bumper skirt still attached). To completely remove the skid plate, three small screws holding it to the front plastic bumper skirt must also be removed.

Toyotafilter kits contain a new filter cartridge, a plastic drain plug, and two O-rings. The drain plug is used to drain residual oil from the filter unit prior to removing the plastic screw-in housing. After removing the large, metal, round screw with a 1/2" square fitting in the middle of it, the plug simply snaps into the bottom of the plastic housing. The smaller of the two new O-rings replaces the existing O-ring on the screw.

Once drained, the plastic screw-in filter housing is removed using a filter wrench (Toyota special service tool). The larger of the two new O-rings replaces the existing O-ring on the screw-in housing. VERY CLOSE ATTENTION must be paid in placing the new O-ring - failure to properly seat the new O-ring could result in a massive oil leak! The filter itself is currently only available from Toyota.

are you talking about the skid plates??

i had a 96 so it may be different... there was a "remote" oil filter under the plastic skid plate just behind the front bumper... it took a flat screwdriver to open an access panel.... just a quarter turn of he screw and the door would open... hope this helps.... let me know... i can keep looking if it doesnt
