Is the fluidamper worth it?

Good deal thanks guys

The water pump will flow a little more coolant with the smaller SD pulley, also the fan will turn a few more rev's for increased cooling. That's a great thing for those in the southwest driving in the dead of summer.

Billy, did you have to get a shorter belt? I have the pulley, but the belt was too long, and the belt I think it takes is special order. I have it now. Just not around to try it. Also figuring when I get time to put the big Mitsu alternator on it will bring it back tot he stock belt again....

For any of the OBS guys wanting to install a Fluidampr, I highly recommend getting the SD water pump pulley. If you don't, get the belt on is a PITA. The OBS pulley is slightly larger than the SD one.

Goodyear PN# 4081190 is a gatorback belt in the correct length for the SD water pump pulley.

I replaced my clutch fan with an electric fan years ago. Works really well up here in Mn.

I have the Mitsu alternator in my truck. I was able to retain the belt specific to the Mitsu equipped motors. I was going to try the non-Mitsu belt but never got around to it. The belt tensioner was within the marks anyways.

Bringing this back...

Just to be clear, I'm ordering a fluid damper, according to what I've read, I should just use this time/opportunity to go ahead and upgrade to the 6.0 fan, and if that's the route I go, I should also order a SD water pump pulley, and a fluid damper for the SD model years. Is that correct? Also, with everything else stock (accessories), which belt am I supposed to use?

I got a fluidamper bnib if anyone interested.

Magnum PD · Sep 20, 2014

Just put the 6.0 fan on the OBS fan clutch and your good to go.

Your stock belt should be fine. The pump pulley is only a little smaller then stock, which is a great move, because that Fluid Damper is too close with our OBS pump pulley.

If go with the Fluidampr, I highly recommend the SD water pump pulley. The OBS is slightly larger and makes getting the belt on a PITA. If you retain the OBS water pump pulley, you need to remove it and install the belt.

I have the 215A Mitsubishi ambulance alternator which requires a different length belt. I reused the belt with the SD pulley. The tensioner was within the tension marks. I have since done the TSB using the SD dual tensioner.

What I'm running:
- Fluidampr
- 6.0 fan
- SD water pump pulley
- SD dual tensioner
- Belt recommended in TSB for dual tensioner
**** You can omit the spacer that comes with the Fluidampr if you use the 6.0 fan

I would order the Fluidampr for the OBS truck. The dampers are the same but the OBS part # includes the spacer for the fan. I would have the spacer on hand if you decide to run the OBS fan.

I have had a fluid damper on my pull truck (that used to be daily driven) for quite some time now. I put it on after the added horsepower wiped out the rubber in the stock balancer and the truck started to eat belts. I Notice my 01 is starting to have a little wiggle in the damper too, and that only has a chip, I will be getting another fluid damper soon. Even if you don't notice a difference in hp or idle smoothness, it's comforting to know the stock one wont come apart. After warming up for a few minutes my idle smooth's out, not sure if it would or wouldn't with the stock damper- 400/400's, gen3, blah blah blah.....

Will the sd dampner work on a obs with the 6.0 fan ?

Yes, it's the same dampner. The OBS kit just includes the spacer for the stock fan/fan clutch assembly. If you run the 6.0 fan, no spacer needed. I am running the 6.0 fan and have the spacer available.

I'm interested in the fluidampr I'm looking for an unused 720221 which is the one for the Obs with the spacer. What price are you looking for?
