relocating the pmd

[sidelined]

I just bought a 1994 3500 6.5TD. I've read a ton on here about relocating the pmd. If the truck already has 99,000 miles on it with no issues, does this still need to be done? And also, here's a rookie question. What is the PMD? :dunno:

yes it does, save you alot of money in the long run.

Yes, it does.

PMD = Pump Mounted Driver. Basically, it gets too hot and dies. It's just a solenoid.

Here's a website that sells a relocation kit and has a decent explanation of what it does, why it fails and why relocating it usually fixes it. http://www.hdiesel.com/product.asp?id=42

Thanks, that pretty well explains it.

The best place to put it is in front of the left side battery, just behind the headlight. The relocation kit should come with a heat sink. Use that to mount it up there. One thing to realize is that not only is the PMD damaged by engine heat, but it creates a tremendous amount of heat itself. It needs to be cooled almost more from that heat than engine heat.

good info, thanks.

actually, may people feel bumper mounting it is the best spot.

Does anyone have any pics of were they actually mounted their PMD? I just picked up a 97 K2500 with a 6.5 and it has the PMD relocate kit from ssdiesel with the big heat sink mounted on the side of the intake. Is that a good spot? It seems to me like thats still a pretty hot area. I'm think about just moving it to right in front of the a/c condenser and mounting it right next to the front horn just behind the grill. Seems like it would get the most air flow there.

i mounted mine to a big heatsink my dad found at work, right behind the pass. side hole in the bumper. ill get pics this afternoon.
under the hood is not a good place for it. it needs to be somewhere where it can get air flow!
