The 3.1t Diesel didn't come with a block heater. My teacher got a coolant heater that pumps heated coolant through the hoses into the top of the engine. On the hoses i put T's that go to the fuel tank which is at the back of the vehicle. The coolant heats the biodiesel in cold winter conditions. A coolant heater is very similar to a block heater. The thing is that the block heater heats the oil pan and the coolant heater well heats the coolant. The coolant heater pumps heated coolant up (the flow of the coolant). I made a mounting bracket out of 16 gage steel. I pre-drilled holes and mounted it with 4 self-taping screws. I bolted the mounting bracket for the coolant heater with two bolts. The are
pictures of the process and of the finished product.
