Coolant Bypass Kit by Fleece Performance Install: 2005 Dodge Cummins 5.9L Automatic

Рет қаралды 120,623

Күн бұрын

Another product from Fleece Performance built out of necessity is the 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 the braided hose to ensure a leak free installation.
Watch us install a Fleece coolant bypass kit on a 2005 Dodge Cummins 5.9L automatic.

I installed this kit in my 07 great product in theory and good quality. My experience was that rear plug was extremely difficult to access/remove with engine in the truck. The plug did NOT rotate, rather went frighteningly evenly into the engine even with a fine piont pick on the extreem edge. My only saving grace was #6 water jacket stopped it from falling in. Oh and the "heat exchanger" is actually referred to as a torque converter cooler wonder if it was intended to stop trans from melting down under the extreemest of conditions. Regardless the cooler has been known to fail subsequently, mixing coolant into transmission instantly destroying it. I feel the Fleece is the only coolant bypass worth buying despite hell to install but recommend closely monitoring trans temp when towing.

Great video and thanks for sharing this replacement kit for the OEM transmission torque converter Oil cooler. I"m considering doing this on an 07, 48RE trans with the 5.9 cummins. Someone else asked about the transmission lines that go into the stock cooler. What happens to those lines when the Fleech Coolant Bypass Kit is installed...? And would there be any issues with more northerly / colder climates up in central Ontario, Canada...?

@jessename7849 5 жыл бұрын

I'd say get the manual transmission one then buy a good aftermarket water to oil cooler & replace the stock transmission exchanger. Then run whatever you need to with new appropriate lines to make it work. Also I hope you know that the transmission needs to be in neutral to pump fluid & warm up.

@sunscapelsv8997 Жыл бұрын

Just installed the bypass while the head was off. Made the job a little easier. *warning* If you live in a warm climate like Northern California be prepared for much higher transmission temperatures in stop and go traffic or heavy towing at low speeds. Trans fluid coming off the converter in these situations is much higher than your coolant temperatures. When you eliminate the heat exchanger you loose cooling capacity. My truck had survived 280k miles without this product in the same conditions. Head gasket blew when my employee drove too long after the water pump went out. This product is definitely oversold and if you live in a warm climate you might have to drop another $1000 on a good frame mounted transmission cooler.

Pretty sure high boost can't pushout freeze plugs unless maybe your head gasket is leaking. Usually from turning higher rpms causing water pump to make more pressure.

@aaronwolf5714 5 жыл бұрын

HorsepowerTube higher boost= higher cylinder temps, which causes more heat transfer to coolant. The issue is that cylinders 5 and 6 receive less than adequate coolant flow causing pressure spikes around those cylinders which can push freeze plugs. Water pumps don’t create pressure only flow
