I have a 2003 duramax and i was wondering if it has a block heater on it,I have looked but cant seem to find it,not sure if its hidden really well or it just doesnt exist.

thanks chris

I had trouble finding mine on my '03. The cord for it is wrapped up in a wiring harness close to the air filter (passenger side), right up against the fender metal, IIRC, maybe on the engine side of the coolant tank. You'll find it: it looks like a flat 3 wire extention cord end. You might need to cut some tape to get it loose. Hope this helps!

Nice pic, John.

Where is the water in fuel sensor wire? Not that its important - but did you remove it?

It's there, you just can't see it. This was a brand new truck so nothing was molested at this point.
