A buddy of mine traded up to a KW T600 with Cat Acert engine. This us the 1st winter he has ran this truck. He has had issues twice already this winter with fuel gelling. He plugs truck in the night before he is scheduled to leave. Truck will start up and idle the next morning. If he throttles up the truck and tries to let it idle, the engine will die. I think he had to change filters 3 or 4 times to get 2 miles back to the farm. Fuel gets treated, but think the owner got carried away and over treated the fuel today. Looking for a fix to the root of the problem. Both my older Pete's have coolant heaters in the fuel tanks. His KW does not have any kind of fuel heater. I think he needs some type of fuel heater. The shop he talked to says he will have problems all winter because of the small micron fuel filter on the truck and cannot switch to a larger micron filter or he will cause issues with injectors. Any ideas? Thanks.
