    The problem is the fuel is to hot and it breaks down an plugs the injectors the fuel filter system holds the heat in they need remote spin on filters Diesel breaks down after 126 degrees so your engine runs at 185 plus a fuel cooler could help or they need Bosch to make there injectors

    After reading this you're making me wonder at those temperatures would it run better up north here in minus 1 to 4 Fahrenheit temperatures? And if so would tbe longevity be better for the motor?

    The motor is a POS and Paccar knows it.

    The problem with the injectors is that our government has to subsidize farmers and they force junk biofuel on us. They’re not having injector issues overseas like we are here.
