Who runs the air to water cooler in with the engine coolant loop? Dodge89-91.4 "Aftercooled"WJCAC(water jacket charge air cooler)put too much heat load on the under sized radiator. So they revamped the system after only 2.5 model years. They didnt adderss the anemic cooling system till the body change in 94.
For my diesel I plan on putting an air to water cooler between the turbos and that coolant is going to be on it's own coolant loop.good place for it as the air will be reheated by the 2nd turbo and if memory serves your planning on the radiator for the WJCAC to be in the bumper so no heat load on the cooling system also good.
How would you regulate the WJCAC temperature@ my -40°f/c ambient temperature to keep it above freezing on a 7 mi cost down a 6%grade? With a heat exchanger? Cross flow from motor coolent to WJCAC coolent ? This could possibly slow the loss of heat. But would remove needed heat from the cab heater/motor.
