Norcal Diesel Performance - Cooling System for 2nd Gen Dodge Ram 12V

Cummins Coolant Bypass Kit. Another product from Fleece Performance built out of necessity is the 2003-2016 Cummins Coolant Bypass kit. The Cummins engine cooling system was designed to adequately cool a 300-350hp engine.

When the horsepower is increased there is an increased demand on the cooling system. The rear cylinders suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the system, especially the rear of the block and possibly blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

We’ve designed our coolant bypass kit with 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. Our kit comes with high quality AN o-ring fittings and AN hose connections with braided hose to ensure a leak free installation.

The 2003-2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is not a fluid cooler; it was designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed.
All 2007-2016 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.

For customers with a 6.7L that has a heat exchanger, You will need a heater tube it can be purchased at your local Chrysler Dealership PN:68048997AA. It is very rare that a 6.7L has a heat exchanger, but we have had a few instances where it has been needed.

Freeze Plug Side Plate

• Fits 6B 12 Valve, 98 - 2002 24 Valve, & 4BT engines

Please Read: 
This kit includes a high temperature Viton o-ring, care must be taken not to cut or damage the o-ring. The freeze plug bore must be cleaned with a wire brush or emery cloth to remove all rust and scale. 

The freeze plug bore must have a small chamfer to allow for the o-ring to compress for a tight seal. Use motor oil to lube the o-ring and freeze plug bore, then carefully install the freeze plug by hand being careful not to cut the o-ring. Do not use a hammer! the plug should slip in with hand pressure only.

Don't risk blowing out a freeze plug in your 1989-2002 Dodge 5.9L Cummins, stop the issue dead in its tracks with the XDP Cummins Bolt-On Rear Freeze Plug XD338. High RPM, heavy acceleration, and temperatures differences in your cooling system can cause a freeze plug blow out. When a freeze plug blows out, it will not only leave you stranded, it also causes large coolant losses that can lead to overheating conditions.

The XDP Bolt-On Rear Freeze Plug is mounted firmly in place using existing bolt holes on your cylinder head. Each freeze plug is CNC Machined from billet 6061 aluminum and is machined with a built-in o-ring gasket to ensure a leak-free seal. The XD338 includes the necessary hardware for installation and does not require removal of the transmission.
Features:

• O-Ring Seal
