Brand new Ecomomy Series FSD Heat-Sync IITM kit, for all GM 6.5 Turbo Diesels with electronic fuel injection used in C/K trucks and Suburbans from 1994-2002. Solves the problem of frequent PMD failure with your GM Diesel at an affordable price.
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 Cooler kit, relocates the PMD to a cooler area of the engine compartment, above the intake, on a massive oversized heat sink. A proven design. Our design has some distinct advantages over all the competition\'s. Please check our "advantages" section on our homepage and our FAQ section for details.
This kit includes everything needed including a new Economy Series PMD, FSD Heat Sync II cooler as pictured, and a stock calibration resistor. Detailed step-by-step instructions also included. No drilling or cable splicing. A truely simple Plug-and-play installation. Professionally engineered and manufactured. Only basic hand tools required. Removal of the top shroud required. Approximately a 10-20 minute installation. See our warranty page for more info.
***WORD OF CAUTION*** Heat Transfer Technology is a science. The sizing of a heat sink requires calculations for the heat sink load of 2-500 watt transistors in an underhood environment exceeding 150DF. The mass of the heat sink, cooling fin design and cooling fin surface area are CRITICAL to PMD life. Although our "FSD Heat-Sync II" runs significantly cooler then most of the competitors, most others will still somewhat do the job. However, I see one out there with little to no "home made fins" that can\'t possibly dissipate the heat of 2-500 watt transistors. Temperature will fry your PMD again in short order. Look to buy the best functioning one, not the prettiest one. Extensive research and engineering have gone into my design. No guesswork involved!
Notes:
Calibration resistor comes pre-installed in the harness connector.
This is a lighter duty imported version of our famed "made in USA" ssd-006 Premium HD FSD Heat Sync
90 Day limited warranty
If replacing a Stanadyne "GRAY" unit (made in Malaysia) with our new advanced technology PMD, you will either need to purchase a ssd-9908B adapter harness, or simply file off the "ears" on your gray end harness for a perfect fit.
