    03 lb7 oil in coolant

    Everything iv read in the last ten min seems so point straight at the oil cooler. Everyone also says your same thoughts about coolant being under more pressure . But from my experience with hydraulics and water systems fluids can do weird things under pressure and at certain angles 03 chevy...

    03 lb7 oil in coolant

    Agreed. But depending on how the fluid is passing over a crack leak or what have you "given there is a leak" and even if the pressure is greater the fluid can also cause a suction.

    Lb7 no start no crank

    Usually I can add power to the crank fuse with a test light and crank the truck. This fixes the problem for a bit but did it again last night and now my test light is showing me red when trying to add power to crank fuse. This means my crank fuse is somehow a ground. Stumped. Any suggestions...

    Radio stays on after key out and door open
