    That's why they have to use loud pipes!

    Clearly you do not know how a Jake works, or you would not say this. No combustion takes place that would raise the oil or coolant temperature.

    The compression does create heat, although not as much as combustion does.
     
    DougA and Bean Jr. Thank this.

    Okay. If you say so. I guess the water and engine oil temp gauge rising and the engine fan activating on longer, steeper descents is just an odd coincidence and/or they're confused.

    No more than just staying in gear without the Jake.

    No. The friction will be the same, the compression that the Jakes use to slow the truck will create heat. That's just basic physics.
     
    DougA Thanks this.

    A truck in gear will generate the same compression. With the Jake on, the compression is released near TDC, with it off, the compression drives the piston down. If you want to say that on the power stroke, that the engine generating suction increases heat, perhaps you could share the physics behind that.

    Oh come on. We all know a jake slows a truck the same way Fred Flintstone stops his car.
