Just as the title says; Do any of the duramaxes use a vacuum pump? I am most interested in the LLY? :confused:

thanks for the help:)

Can't answer for the LLY, but my 2001 LB7 sure doesn't. As far as I know, all the DMaxs use "hydroboost" off the power steering pump for power brakes and none use vacuum.

There is an aftermarket solution if you are trying to run vacuum trailer brakes. Buddy of mine did it because it was cheaper than switching over a couple of trailers.

anybody else? I am just trying to find out if my truck has a vacuum pump so I can get the correct serpentine belt. nobody seems to know, even the dealer.:confused: both goodyear and gates have applications with or without vacuum pumps.

please help:o:

My '05 LLY has no vacuum pump (that runs off the serpentine belt, I assume that's what you are asking). Pose this question in "Ask the Techs". If anyone could answer, they have probably answered this before.

if your dealer doesn't know then I think you need to find a new freakin dealer.
