I just wanted to say thankx for putting up with my hundreds of questions about the truck i just wanted to make sure i'm not wasting my money. i just got your cold air intake in today, (Early christmas gift from the wife) TURBO!! i have a turbo? i can...

Walt, all I have to say is wow. Should have done it a long time ago. I'll hit you up when it's time for exhaust. Thanks again, Max

Brand new FSD Heat-SyncTM with #9 resistor, for all GM 6.5 Turbo Diesels with electronic fuel injection in C/K trucks and Suburbans,1994-2000. Manufactured in USA by SSDiesel SupplyTM, 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 Advantages" on our home page for a list of our distinct advantages over the competition's, including the one without fins.

Includes everything EXCEPT A NEW PMD to complete the installation. (shown for reference in photo only) I also offer the cooler "kit" which includes a new PMD. Please check the products page for the "kit" version. 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 our NEW PINK heat transfer pad proven to transfer heat better then any other. (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. Removal of the top shroud required. Only basic hand tools required. No drilling or cable splicing. A truely simple "Plug-and-Play" Professionally engineered and manufactured in the USA by SSDiesel SupplyTM.

***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. Although our "Heat-Sync" runs significantly cooler then the competitions, (check the "advantages" section on our homepage and FAQ section) 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. Look to buy the best functioning cooler, not the prettiest one. Extensive research and engineering have gone into my design. No guesswork involved!

If relocating your existing PMD, make sure it is worthy to do so. If it has over 30K miles on it, or has ever shown signs of failure, leave it be and install a new PMD on the Heat Sync. In that case go with our ssd-006 SSD Heat Sync kit. A Heat Sync won't fix an already bad PMD, just prevent future damage. If relocating your old PMD, please contact tech support for details.

Included in the box: 1) FSD Heat Sync, 4) Grade 8 mounting screws, Instructions, 1) Silicone mounting pad, 1) #9 calibration resistor (other values available on request), (2 only shown in photo to view both sides)
