Having a cooling system problem on a car d9r...

Working on a d9r ser#7tr00814...complaint is a flashing coolant flow light and overheating after working for an hour or so. When you idle the machine up, he flow light goes out. Rad & water pump have been replaced & rebuilt & one thermostat changed when pump was out. Other thermostat has same temp before & after so seems alright. I dunno, am I missing something? Oil cooler plugged?

Hi Dave, My name is***** will be glad to help. If you already did the radiator, T stat, and pump and a good flush with cascade powder detergent then I agree with the cooler is the next step as well as looking at the sensor and wiring harness in case there are false readings. Check your actual temps and confirm you are not running hot. Let me know
