2008 Buick Enclave Oil Filter

You need to position a new Oil Filter Adapter gasket onto the oil filter adapter, place the oil filter adapter into position, and then install the oil filter adapter bolts, a new oil filter, and the generator.

You need to install the 8 mm (0.315 in) guides from the EN 46109 into the center Oil Pan rail bolt hole on each side of the engine block, place a 3 mm (0.118 in) bead of RTV sealant, GM P/N 12378521 (Canadian P/N 88901148) or equivalent, on the block pan rail and the crankshaft rear oil seal housing, position the oil pan onto the block, remove the EN 46109 8 mm (0.315 in) guides from the engine block, install the oil pan bolts, tighten the oil pan bolts in the sequence shown, install the air conditioning (A/C) compressor and the exhaust flexible pipe, lower the vehicle, refill the engine oil, and then connect the battery negative cable.

The procedure is to turn the ignition off, remove the oil level indicator from the oil level indicator tube, the oil level indicator tube bolt, and the oil level indicator tube up through the exhaust manifold, and remove and discard the old seal if you are replacing only the oil level indicator tube seal.
