Are you in Alaska? What heater can you plug in that is not already connnected. A diesel preheater maybe.
The engine won't start or will be hard to start in cold weather unless you have the motor heater plugged in.
You need to have the intake heater grid tested.
No. You unplug the block heater BEFORE you start the truck.
Not unless it is plugged into a wall outlet.
Your 99 diesel will only start running when the block heater is plugged in because your glow plugs need replaced. The fuel is not reaching a high enough temperature to initiate compression.
Jump start car and do not run heater with engine not running.
Yes you can, just don't forget to unplug it before driving off! I would advise not to do so, a block heater can experience thermal shock if plugged in while starting your engine causing the element to crack.
Heater works fine in my Wrangler! Check the thermostat or the hoses or heater core might be plugged. The thermostat is easiest ^ cheapest to change so start there.
Start with flushing both heater cores. The rear one may be plugged with crud.
it doesnt matter how long u leave the block heater plugged in. i plug in when i am done driving for the day. the longer the heater is plugged in the warmer the engine is when u start it Block heaters are a huge draw on electricity. If you are plugging it in regularily, you can save yourself a ton of money by adding a timer. 2 or 3 hours is more than emough to start any light duty diesel in any weather. If it is having trouble starting after 3 hrs, the engine has issues.
pump bad or dirty replace
4x4's & p/u's have the starter harness running in back of the motor(intake manifold) down by the heater case--U might have caught the wires under the heater case or Evaporator case.
