Brand new FSD Heat-SyncTM kit for all GM 6.5 Turbo Diesels with electronic fuel injection in G/P vans (Chevy Express and GM Savana) and cab/chassis trucks, such a school buses 1994-2002. Also 96 and newer H1 Hummers. Manufactured in USA by SSDiesel SupplyTM, GM 6.5 TD specialists. Solve the problem of frequent PMD failure with your GM Diesel. Featuring our new SSD Advanced Technology PMD which outperforms all previous PMDs in performance and longevity.
LIFETIME WARRANTY ON PMD, please see warrant policy page for details
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/throttle 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 for a list of our distinct advantages over the competition's, including the one without fins.
This kit includes everything needed including a new SSD Advanced technology PMD, FSD Heat Sync cooler as pictured, and a #9 calibration resistor. Detailed step-by-step instructions also 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!
Notes:
Pictures show FSD Heat-SyncTM kit mounted to G/P Van-Bus intake manifold for demonstration and fitment purposes only. Intake manifold NOT included.
Not a direct bolt-on for NON-Turbo applications.
