pliedradiatorhosealongthelineshown.
2. Install the right end of the hose in Figure 3 onto the EFR-100 oil  lter
adapter’s radiator hose barb and secure with the provided worm clamp.
3. A 1.75” to 1.50” hose reducer, part number RHR-175-150 (sold sepa-
rately) is required to connect the EFR-800 hose to the inline coolant

1. The recommended moun ng loca on for the remote  lter pedestal is
the le side of the bumper bar, facing rearwards. An exis ng moun ng
hole in the bumper bar may be used so that only one addi onal hole
needs to be drilled.
2. Secure the moun ng bracket to the  lter pedestal and posi on it against

the bumper bar with threaded backing plate and screws provided, as
shown in Figure 4.
3. Level the lter pedestal mark the unused hole locaon.
4. Remove the lter pedestal assembly from bumper bar.
5. Strike the hole center with a sharp punch.
6. Drill a hole into the bumper bar using a sharp, high-quality, cobalt steel
3/8” drill bit. The bumper bar is made from very hard steel and a good
cobalt steel drill bit is required to cut through it.
7. Reinstall the bracket and backing plate onto the bumper bar using two
screws from the lter pedestal hardware kit. Torque the screws to 24
lb- (33 N-m).

8. Use the two plugs provided with the ENV-140 to plug the unused ports
as shown in Figure 5.
9. Connect the oil lines provided between the EFR-100 and ENV-140 as
shown in Figure 5.
a. Connect the 45-degree hose ends to the EFR-100.
b. Connect the 150-degree hose ends to the ENV-140. Note the
orientation of the hose end ttings in Figure 4.
WARNING: Ensure that the lines are connected correctly, or oil ow to
the engine will be blocked.

1. Check that all lines and ngs are snug.
2. Check the engine oil level and add oil if necessary.
3. Rell the engine’s coolant system using the manufacturer’s approved
method for your specic vehicle.
Tip: Consult the vehicle’s factory service manual for the correct coolant
specicaons and rell procedure.
4. Start the vehicle and inspect for oil and coolant leaks.
 IMPORTANT:Checkthattheenginehasoilpressureimmediatelyaer
startup.Iftheoilpressureisabnormaloriftheenginemakesexcessive
noisethatdoesnotsubsidewithin3-5seconds,turnotheengine
immediatelyandchecktheoillineconneconsforroungerrorsora
kinked oil line.
5. Turn-o the vehicle, inspect the engine oil and coolant levels and add
oil or coolant as needed.
6. Reinstall the front bumper and all underbody panels. Lower the vehicle
back onto the ground.
7. Inspect lines and ngs for leaks aer one heat cycle. If any leaks are
