PMD Isolator System for 1994 to 2000 6.5L C or K Truck and Suburban
The Isolator mounts on the transmission cooler mounting bracket for C-K trucks
and suburban diesel with Automatic Transmissions. For manual transmission, it
mounts on the factory holes designed for the transmission cooler bracket.
The electrical connection at the PMD is a sealed, weathertight type that is
not affected by water, mud, or snow. The PMD Isolator is a very durable design
and is not susceptible to road hazard damage. Step 1: The install can be
completed by either loosening the front grill and tilting back, or gaining
better access by removing the front grill. To remove the front grill, there
are several video tutorials that can be found.
Step 2: (AUTOMATIC TRANSMISSION) SEE FIGURE 1 Locate the transmission cooler and remove the top mounting bolts. (Yellow Arrows). Using the new stainless steel mounting bolts in the new kit, install the Dieselsite PMD aluminum isolation plate with the PMD mounted. SEE FIGURE 2
(MANUAL TRANSMISSION) SEE FIGURE 4 Locate the two holes in the upper part
of the frame that the PMD Isolator Plate will mount. (Yellow Arrows). These
are the holes used for the bracket for the cooler for automatic transmission.
Using the supplied self-drilling screws, attach the PMD Isolation plate. SEE
FIGURE 3
Step 3: Once the isolation plate and PMD are mounted, you will need to
connect the harness to the PMD and carefully route the new DieselSite
extension harness up to the factory pump harness. We suggest removing the
factory pump harness from the old PMD located on the side of the Injection
Pump so you can identify where the new DieselSite extension harness must
route and attach.
Step 4: SEE FIGURES 5 & 6 The next step is to release the latch holding
the factory pump harness to the PMD mounted on the fuel injection pump. When
the latch is released, the connector will move backward and out of its
connection to the black box. On dual thermostat engines, this can be a little
tough to get to. Use a screwdriver or pick to raise the latch, then slide it
out of the old PMD module.
Step 5: Route the harness from the new PMD Isolator plate being careful
to fasten it away from pulleys and belts and connect it to the factory pump
harness. Use the zip ties included in the kit to secure the new cable.
Finally, tuck the newly made connection back down into the area adjacent to
the injection pump as shown.
