Hi guys, my first diesel as you may know, I was under the truck messing with the exhaust and saw this...
If you notice the loose connector on the lower end of the picture with 3 female prong holes, it comes directly from the plug end hanging out of my grill. I looked for a while but didn't see where it plugs in! Has the block heater been removed? Should it be right there in front of my face?
No clue if it's been removed or not, but it replaces one of the block plugs there on the passenger's side of the block. Check right around the front end of the starter, or just behind IIRC.
Ok, so I found it, above the starter. Thanks! I had no idea what to look for. Now to see if it works. Don't think it's been used in forever... The connectors were a little corroded but tried to clean them off.
You can buy the cord separately if you find it doesn't work, they fail more often than the heaters. A simple ohm meter check will diagnose, but of course the easiest test is to plug it in and see if it works.
It doesn't seem to be working. I'm surprised with the truck because it's been starting (albeit hard and rough) in the -6 degree weather we've been having here. Unless I let it sit for 4 days, did that once.
I'll have to run a diagnosis. What should the ohms read.
Not sure on ohms but you could do the math using ohms law, 120v and 1000w. More simply continuity is good and open is bad. Check at both flat terminals on your plug. It should be open fom either of the flat terminals to the ground. If it is open on the flat terminals, unplg the cord from the heater and check from one end of the cord to the other.
with cord disconnected at both ends, and using a multi meter, set it for the lowest ohm setting. then just look for continuity between the ens on all three wires. if you get zero or close to zero ohms in all three, the cord is good and the heater is bad.
