The heat exchanger is 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. For model years 07.5-18 6.7L trucks, including both automatic and manual equipped transmissions, factory installed transmission fluid heat exchangers are uncommon.100% quality assurance tested, more responsive, less expensive, easier to install. Lower coolant temperature at the rear cylinders. Ensure consistent temperatures across all cylinders. Prevent damaging coolant pressure build up.

Why Need a PQY Coolant Bypass?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.
The PQY Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform. Dislodge the freeze plug out of the rear engine. Clean plug hole surface by scouring pad. Assemble braided hose to thermostat housing.Line up housing to rear hole, push it and bolt it down. Assemble thermostat riser block to the other end of hose with wrench. Put non-O-ringed side of block against the front thermostat. Set stock thermostat on top, 3 bolt to hold them on.
Adjust the hose position to fit engine. Install 2 hose fixing brackets or clamps to hold hose. No installation guides are included, we highly recommend to seek professional installation.
