Fleece Performance 06-07 Auto Trans Cummins Coolant Bypass Kit w/ Stainless Steel Braided LineIncreased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5. 9 6. 7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5.9/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. Benefits: Lowers coolant temperature at the rear cylinders Ensures consistent temperatures across all cylinders Prevents damaging coolant pressure build up Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation. Kits for MY 2003+ include billet hose brackets. Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform. Application Notes: The 2003 - 2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is designed for use in cold climates to warm the transmission fluid with the engine coolant.

Value replacements
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
As far as I can tell these are pretty solid replacements for the SAROS 10R. My original side brush was all torn up after just a few months of use so I found these replacement parts. Haven’t used the mop pads yet, but they are a similar design to the “upgraded” mop pads offered by Roborock which are superior to the standard one IMO. Everything else seems to be equal quality to the OEM parts, and at less than $12 I have no complaints on this kit.

Does not work for Qrevo Arc.

Filter does not fit my Qrevo Arc. Photo shows size comparison between my old (very dirty) filter and the replacement filter.

Solid replacement parts kit — just skip the mop pads
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
This kit has been a handy all-in-one refresh for my robot vacuum. The main brush, side brushes, filters, and dust bags all fit correctly on my Qrevo, slid in without fuss, and have been performing on par with the originals — suction feels unchanged, the side brushes kick debris toward the intake properly, and the filters look and seat identically to the ones they replaced. My one real complaint is the mop pads. They're noticeably thinner and flimsier than the OEM pads, don't hold water as well during a run, and left streakier lines on my floors compared to what I'm used to. I've ended up going back to the original-brand mop cloths and just using this kit for the dry-cleaning parts, which have genuinely been a good value. Four stars — great kit minus the mops.

Convenient Roborock Kit, but Quality Feels Lower than OEM
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
This is a convenient accessory kit for Roborock products, but my experience was mixed overall. I have a QX Revo Pro, not the Ultra, and I realized after the fact that the main brush in this kit is not compatible with my robot vacuum. That was my mistake, but it does limit how useful this particular set is for me. The kit includes a variety of parts, and it is nice to have so many replacements on hand in one package. However, the overall quality feels disappointing compared to my original Roborock accessories. The disposable vacuum bags are noticeably smaller than my OEM bags, which makes me question how often they will need to be changed. The mop pads also seem thinner and less substantial than the originals, and they do not look or feel like the same quality material. Because of these differences, I am concerned about the long term performance and durability of the replacement parts in this kit. While it is convenient and generally compatible with Roborock models, I am not confident that these accessories will hold up or clean as well as the OEM parts I am used to.
