Chrysler 3.6 Runs Hot
Hello, customer complaint is that van went over 250 degrees when climbing a local mountain. Found bad looking antifreeze so I replaced radiator, thermostat, coolant temp sensor, and rad cap. Flushed cooling system and test drove but still ran around 240 cruising 55mph with A/C on. Cooling fan seems to be flowing decent amount of air on high at these temperatures. Suspected water pump fin damage so I removed that but no issue found there. Customer agreed to replace that anyway so I did. After filling and bleeding cooling system engine still runs around 240 and does not seem to be able to come down from that even at idle after a test drive. We had originally verified when the engine was cold that the ambient temp and CTS were within 10 degrees of each other. Any help would be greatly appreciated. Thank You
What are you measuring the engine temperature with? Infra red camera? Non contact thermometer?
