SUGGESTED MOUNTING

POSITIONS

Determine the best cooler location for
your vehicle from the positions shown
in the illustration. Position 1 is the
preferred location, but positions 2 or 3
are acceptable. Other positions can
be used, but they must be locations
where there will be a good, cold airflow
through the cooler. The cooler can be
mounted with the fittings facing up,
down or to either side as is convenient.

INSTALLATION

Before starting the installation, check
the oil filter clearance by adding twice
the depth of the sandwich adapter to
the filter length. If there is insufficient
clearance the filter must be remotely
mounted. In some cases a short filter
will suffice. Make sure that the threads
on a shorter filter will fit the adapter.
STEP 1. Install the 1/2" NPT fittings
into the cooler and the 3/8" NPT fittings
into the sandwich adapter. Use Teflon

tape or suitable thread sealer. Do not
overtighten.
STEP 2. Position the cooler in the
location that you have determined. Do
not install the cooler yet.
STEP 3. If your kit includes more than
one mounting nut adapter, select the
correct one for your car. This is easily
determined by test threading the adapter
into your oil filter. Select the one that
you need and set the others aside.
STEP 4. Apply a light coating of engine
oil to the O-ring seal of the sandwich
adapter. Insert the correct mounting
nut adapter through the adapter and
screw it over the threaded nipple in the
cylinder block. The O-ring seal side of
the adapter goes against the block.
Locate the fittings on the sandwich
adapter in the direction that the hoses
will be routed. Tighten the mounting
nut adapter.
STEP 5. Fit and cut hoses to length
(add 1" and keep 3" minimum radius)
and attach to cooler.
STEP 6. Attach the cooler to the radia-
tor or A/C condenser using mounting

ties, making sure that the four rubber
pads are installed between the cooler
and the radiator or the A/C condenser.
STEP 7. Complete the hose assem-
bly, keeping well away from unpro-
tected sharp edges, exhaust system,
etc. Trim the hoses to the final length
and tighten the hose clamps per in-
structions. Use tie wraps to secure
hoses if necessary.
STEP 8. When installation is com-
plete, test as follows:
a. Start engine; immediately check for
oil pressure. If there is no oil pressure
turn the engine off and look for the
problem.
b. Place the car in neutral and idle for
ten minutes with the parking brake on.
c. Check for possible leaks.
d. Feel both ends of the cooler to be
sure that they are warm. If not the oil is
not flowing and needs to be corrected.
Check the diagram for proper oil cir-
cuit.
e. Check the oil level. Some additional
oil may be needed, but do not overfill.
f. In a few days recheck the system for
leaks and correct operation.
