Help eliminate the possibility of scored rear cylinders and blown freeze plugs in your 5.9 Cummins with this Coolant Bypass Kit from Fleece Performance! The Fleece Coolant Bypass with Stainless Lines solves the problem of excessive coolant pressure before it becomes a problem. The integrated secondary thermostat locates at the back of the block and allows coolant to flow freely when at normal operating temperatures ensuring consistent temperatures across all six cylinders and eliminates excessive pressure. The kit comes with high quality AN o-ring fittings and AN hose connections with braided hose to ensure a leak free installation and installs in two hours or less!Increased Coolant Flow, Decreased Coolant Temperatures - The rear cylinders on the 24 Valve 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. Fleece's 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.
Why do I need a Fleece Coolant Bypass? - One of the biggest issues on the 24 valves 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.

Useful
It looks a bit thinner than the original Apple one, but it performs just as well in use. It charges very quickly, and the cable is also very sturdy.

LOVE THEM🩷
Love these charges so much and have been using them for years! However, each charger only lasts about 6 months. I think they are worth it though and very good. It comes with two so you only need to buy a new pack once a year. Most chargers nowadays don’t last anyway. These charge fast and are very long. Also love the color options, I have mine in pink🩷

Long Cables and Easy to Spot
Size: 10FT, Color: Blue
So far these have been great chargers. They charge quickly and we have not had any issues with them overheating or causing problems with our iPhones, which is always my main concern with third party chargers.
The 10 foot length is a big plus. It gives plenty of flexibility whether you are on the couch, in bed, or working at a desk. The extra length makes a noticeable difference compared to standard cables.
I actually bought the blue set for my wife so her chargers would stand out from all the white ones around the house. That has worked perfectly. They are easy to identify and no one else grabs them by mistake. The two pack was ideal for that reason, giving her one for the bedroom and one for another room.
If you are looking for a fast charging option with longer cables and want something that is easy to distinguish from the usual white cords, this is a solid choice.

Great block & cables!
Size: 10FT, Color: White
Chargers work fantastically! Charges iPhone 16 superfast as well as new larger iPads. I’ve also used it to charge my MacBook Pro, which it works well with that as well. Doesn’t seem to get excessively hot and the cables are of high-quality. Have bought a lot of these so far and love them!
