VERIFYING SLEEVE NUT THREAD SIZE
Included in this kit should be a sleeve nut with thread specification as
indicated by the part number purchased and the product packaging. The
thread size can be verified by screwing the male end of the Sleeve Nut into
the new or old engine oil filter. If it is incorrect, please contact your dealer.
1. Remove the factory oil filter from the vehicle.
2. Using a rag, clean the oil filter landing on the engine.
3. Take the supplied Sandwich Adapter and Adapter Plate.
4. To determine if your application uses the supplied Adapter Plate, first hold
the Adapter Plate up to the oil filter landing on the engine block. The
casting needs to seat directly onto the landing without obstruction.
If the Adapter Plate is too large, then disregard the Adapter Plate and
O-ring.
5. Take the supplied Sandwich Adapter and hold it up the oil filter landing on
the engine block. The casting needs to seat directly onto the landing
without obstruction. (See Diagram #1)
