Brand new FSD Heat-Sync^TM kit for all GM 6.5 Turbo Diesels with electronic fuel injection in 96 and newer H1 Hummers. Manufactured in USA by SSDiesel Supply^TM, GM 6.5 TD specialists. Solve the problem of frequent PMD failure with your GM Diesel.

The PMD (pump mounted driver) is that small black box mounted on the side of your injection pump. It is a signal amplifier that powers the fuel solenoid. It contains 2-500 watt transistors which create a lot of heat. The factory mistakenly mounted this PMD module on the side of an already hot injection pump and in the engine valley below the intake manifold where temperatures skyrocket. As everyone knows, electronics do not like heat and they will fail prematurely. Symptoms of failure are stalling, hard starting, surging, poor fuel mileage, erratic idle and finally no-start. When they go it usually will not give any codes with the SES (Service Engine Soon) light. This American Made Cooler, relocates the PMD to a cooler area of the engine compartment, above the intake, on a massive heat sink. A proven design. Our design solves the flaws in all other cooler designs. Please click on "FSD Advanatges" on our home page fora list of our distinct advantages over the competition's, including the one without fins.

This kit includes everything including a new latest version PMD to complete the installation. Also included is 1) cooler as pictured, grade 8 mounting hardware (required to obtain proper torque for heat transfer), brand new  #9 performance calibration resistor, and industrial heat sink compound for mounting PMD to cooler (proven better heat transfer then using a pad). (other resistor values available upon request at no extra charge) The original harness will plug right into module with no modification or strain on wires. Detailed step-by-step instructions included. Only basic hand tools required. No drilling or cable splicing. A truely simple Plug-and-play installation. Professionally engineered and manufactured.

***WORD OF CAUTION*** Heat Transfer Technology is a science. The sizing of a heat sink requires calculations for the heat load of 2-500 watt transistors in an underhood environment exceeding 150DF. The mass of a heat sink, the cooling fin design and cooling fin surface area are CRITICAL to PMD life. No guesswork involved!

Note: Pictures show FSD Heat-Sync^TM kit mounted to H1 Intake Manifold. Intake manifold NOT included.

Not a direct bolt-on for NON-Turbo applications.
