As always, if you have any questions about which Fleece turbo, fuel, engine, or other product is right for you, do not hesitate to give us a call and we would be happy to assist.
We get a lot of calls and e-mails each day with various product,
vehicle, and installation questions. Some are completely off the wall
and can even catch us off guard at times, but many others are fairly
routine, so we thought we'd post some of the most popular questions that
can hopefully be a good resource for you.
Q: What other parts do I need to install this 6.7L Cummins Cheetah turbo?
A: Fleece Cheetah Turbos include all of the necessary gaskets and seals you'll need for a complete installation. That said, we do recommend replacing the oil feed and drain lines as they are prone to leaking and its a simple replacement when you have the turbo removed. Is it required? No, but a good investment for sure.
Q: Will the Fleece Allison transmission lines work with an aftermarket transmission cooler?
A: Unless otherwise noted, the transmission line kits are intended for use with a stock transmission cooler, or one with stock style fittings. If your transmission cooler has been relocated, its likely that some modification may be necessary.
Q: Is the Coolant Bypass Kit easy to install?
A: Fleece's Coolant Bypass Kits are considered a "bolt-in" installation with exception to removal of the rear freeze plug that just needs a pry bar and a hammer to remove. While the space is somewhat limited at the rear of the block to remove the freeze plug, a little patience and good lighting can go a long way.
Q: Whats the difference between the 2007.5-2012 and 2013-2018 Cummins Cheetah turbo?
A: While both iterations of these turbos are originally manufactured by Holset and both a Variable Geometry Turbo (VGT), they are inherently different turbos. The turbo found on the 2007.5-2012 model years is an HE351VE and the one found on 2013-2018 models is an HE300VG. Many would argue that the factory actuators found on the 2013-2018 versions was more reliable than the 2007.5-2012's, which we would agree with that, Fleece has done extensive work to ensure the longevity of their turbos and actuators, thus we would not recommend installing a 2013-2018 Cheetah turbo onto a 2007.5-2012 truck with an adapter harness.
Q: Do I have to replace my oil feed line when changing my turbo?
A: No, you do not have to because the turbos are designed to accept the factory fittings. That said, we would recommend replacing the oil lines because its good practice to replace them with the turbo out of the way and the stock pieces are susceptible to cracking and leaking.
Q: Can I use the Fleece Distrution Block with a single CP3?
A: While the distribution block could be ran with a single CP3, you will have to source plugs for extra ports on the block. Otherwise, if you have no intention of upgrading to a dual CP3 kit in the future, we would recommend one of Fleece's Fuel Filter Deletes.
Q: What is the difference between the 2003-2004 versus the 2004.5-2007 Cummins Cheetah turbos?
A: The factory turbo found on the 2003-2004 model years is a Holset HY35W where the 2004.5-2007 is also a Holset, but a HE351CW model. In terms of the actual differences between those two, the HY35W has a 56mm compressor wheel and a 9cm turbine housing, where the HE351CW has a 60mm and 9cm, so obviously a little bit larger. Further, the HE351CW has an electronic wastegate, where the HY has a mechanical version. Both Cheetah versions of these turbos are modified to be a 63mm compressor and an upgraded mechanical wastegate. That said, these are still slightly different turbos, so please make sure to select your correct model year.
Q: What is the CP3K? The listing mentions a 3,000 RPM defuel, what does that mean?
A: Factory CP3 injection pumps lose rail pressure above 3,000 RPM, limiting power potential when you'd typically need it most. Fleece's line of CP3K pumps are basically stock pumps that eliminate this fuel flow restriction.
