COOLER LOCATION
Diagram #1
When selecting the best location for your vehicle, always consider a location that will
deliver the maximum airflow.
The Oil Cooler can be mounted in multiple locations on your vehicle. Reference Diagram # 1
for possible cooler positions. #1 is the ideal location, #2 is second best and #4 being the last
choice.
Note: The Cooler core will flow in either direction, there is no specified inlet or outlet port.
PRE-INSTALLATION
1. Slide one hose clamp on each end of the supplied Hose.
2. Using a dab of oil lubricate each end of the hose and install hose onto the 1/2” inlets on the Oil
Cooler forming a loop.
3. Secure in place using the Hose Clamps. (See Diagram #2)
COOLER MOUNTING
(See Diagram #2)
1. Identify the 4 Mounting Rods, 4 Mounting Clips and 4 1x1 Foam Pads.
2. One by one, Install the 4 Mounting Rods thru the Oil Cooler.
3. Take the 1x1 Foam Pads supplied, peel off the paper lining and slide
them onto the Mounting Rods, sticking them against the Oil Cooler.
4. Take the Cooler Assembly with attached looped hose and hold in the
desired location.
5. Install the 4 Mounting Rods thru the Radiator/Condenser core.
Warning: Do not use excessive force when pushing the Mounting Rods
through the Radiator/Condenser. Excessive force could cause damage to
the fins and possibly puncture a tube.
6. Take the Mounting Clips supplied, making sure they are in the correct
direction (Derale writing out) install onto the Mounting Rods and cinch
them until the 1x1 Foam Pads are slightly compressed.
7. Cut off any excess Mounting Rods.

IMPORTANT
In most cases the Factory Oil Filter will work with the supplied sandwich adapter. In some applications where the frame or
exhaust system interferes with the new filter depth we recommend using a shorter filter length.
See chart below for possible filter options.

SANDWICH ADAPTER INSTALLATION
Diagram #4
Note: This kit is designed to fit GM vehicles Manufactured between
Sandwich
1963-2007, primarily SB & BB V8’s.
Adapter
The Sandwich Adapter fits between the oil filter and the engine block. Before
removing the oil filter, check the clearance between the bottom of the filter and
the closest vehicle obstruction. If there are none, then proceed with the
installation. Otherwise, the Sandwich Adapter is 2-1/4” Thick, so you will need Sleeve
2-1/2” more clearance then stock. If you determine that the stock filter will not
Nut
fit, refer to the Filter Chart for alternative filter heights.
‘O’Ring
1. Remove the factory oil filter from the vehicle.
2. Take the Sandwich Adapter and the two Hose Barb Fittings provided.
Using Thread Sealant Tape, screw the Hose Barb Fittings clockwise
into the Sandwich Adapter until snug. (See Diagram #2)

Fittings
3. Using a wrench tighten the two Hose Barb Fittings.

5. Making sure the engine block filter landing is clean from oil and dirt,
take the Sleeve Nut, Sandwich Adapter, O-ring, and install onto engine
sliding the Sleeve Nut thru the Sandwich Adapter. Turn sleeve nut
clockwise onto the engines filter nipple. (See Diagram #2)
6. Using a Torque Wrench, torque the Sleeve Nut to 20 ft. Lbs.
ROUTING HOSES
1. Using the remaining Hose Clamps supplied, route the looped hose carefully along the frame to the Sandwich Adapter already
installed on the engine making sure to stay away from moving parts, exhaust systems and any sharp objects.
2. Cut hose at desired length.
3. Connect the outlet port on the Sandwich Adapter to either port on the oil cooler.
4. Connect the inlet port on the Sandwich Adapter to the remaining port on the oil cooler.
5. Tighten Hose Clamps.
6. Using the 6” Zip Ties supplied, secure hoses in place.
Warning: When routing hoses, be sure to keep all hoses away from sharp edges, moving parts and hot engine components.
Hoses should be routed carefully and should not be bent in less than a 3” radius.
Important: A kinked hose will restrict flow and could cause transmission failure.
VEHICLE TESTING
1. Start the engine and quickly check all connections for leaks.
2. Turn-off the engine and check oil level.
3. Add oil as needed.
Warning: Installation of accessories should only be undertaken by those with mechanical knowledge and are familiar with working on
vehicles. Always use eye protection (goggles, safety glasses or shield). Park the vehicle in a well lit area, on level ground and apply the
parking brake. Only work on a cold vehicle that has been sitting overnight, failure to do so will result in severe burns and injury. Before starting
the vehicle, make sure no tools or any other items are left under hood that could interfere with or be drawn into moving parts of the engine.
Failure to follow instructions can lead to severe damage and personal injury.
