Transmission Cooler Flow Direction Types Diagram By. the coolant system in a car cools the engine. the coolant flows through the radiator in the engine bay and then passes to the water pump. the water pump pushes coolant out of the system, where then it absorbs all the heat produced by the cylinders. finally, the cooled fluid exits at lower pressure and will flow back into the system. As already mentioned, the flow direction of the transmission cooler is such that the top hose attachment is the hotline, and the bottom one is the cold line. the hotline is the fluid returning from the transmission, and the cold line is the fluid returning into the transmission. however, that’s just a rule of thumb, so it could be the other.
6l80 Transmission Cooler Line Diagram Flow Direction The direction of flow for the transmission cooler. the top hose connection on the transmission cooler is the hotline, and the bottom is the cold line, as previously described. the fluid entering the transmission is on the cold line, while the fluid leaving the transmission is on the hotline. that’s only a generalization, so it may be the. Location. iowegia usa. oct 18, 2003. #5. the high pressure line (hot fluid) from the tranny usually goes to the top of the radiator (internal) cooler tank (an internal heat exhanger in the radiator). the bottom line (lower pressure) but cooler fluid returns to the transmission. this is where you make the break. The optimal direction of transmission cooler flow is from the transmission to the cooler and then back to the transmission. this allows the transmission fluid to: absorb heat from the transmission. get cooled in the cooler. return to the transmission to repeat the process. this guide will discuss the intricacies of transmission cooler flow. 4l60e cooler line flow direction. the 4l60e transmission cooler line flow is very easy to follow. as the gif above shows, the bottom line is the hot line which sends warm transmission fluid out to the factory trans cooler within the radiator at the lower port in most cases. fyi, some vehicles have the factory cooler on the bottom of the.
