I'm not sure where the engine block heater is on my truck... let alone if I have one or not. Where is it located? Also how hard is it to put one on? Does it use a freeze plug hole like what's on a tractor?
Could not find mine either. Went to dealer he had a hard time finding it. 04 dmax LB7 IS mine. It was tied up tight with two ties behind the passenger side battery. best way to see it was stand on tire peer in look straight down , it is attached to one of those ribbed black plastic wiring conduit thingies.
Really look !! I dont think they want us to find it.
The only way that thing will give you heat right off the bat is if you live near the equator and keep in it a tin roof garage. All it does is warm the coolant so starting is a bit easier on the engine. You will get heat in the cab faster, but if you live in a cold climate it will by no means be quick/right away. At 20 to 30 below I start the truck and let it idle for 15 to 20 minutes (don't have a high idle mod yet). Using the block heater I get warm air about 3 miles from the house instead of 4. That's warm air, not hot.
The cord will go down into a black plastic ribbed shell. Cut the electrical tape from the top & this ribbed shell & you will see it is split. The cord will then pull all the way down the split as long as you want. Then route it on the inside of the frame rail to the front tow hook. Works great by the tow hook instead of lifting the hood each time to plug in.
