block heater

[2Dillonslackey0]

ok so i was trying to find my block heater the other day and i cant seem to locate it! it seems like there is no cord whatsoever!!! so my question is how do i know that everything is actually there in the block so to speakand where can i get just the cord if thats all i need?

look for a 2 prong connector just above the oil filter mount...if its there you will probably see the cord connected....hth

Goto your Oil filter. The oil filter screws onto the oil cooler. The oil cooler houses the block heater right above the oil filter, and should have a cord coming from it.

Most of the time the cord is hidden in the core support somewhere.

Every truck has a block heater, but some trucks have had their cord removed, or someone never replaced it.

what if you cant hear it come on ?

You wont hear it come on. It makes no noises unless its DEAD quiet outside, and your standing a foot from it, youll hear slight bubbling noises.

If it sparks when you plug it in, its working.

I've heard them bubble and hiss before on my other two trucks bit this one doesn't do anything haven't really needed it even though I started it up when it was 15 but started on the second try no problem no heater plugged in

Usually there is no sound from a 7.3 block heater. The ultimate way to ensure they are working is to measure the current draw with a cheater cord and clamp on ammeter.

You can also check the heater/cord for continuity. Measure across the blades with an ohm meter. Resistance should be 10-15 ohms. Open circuit from either blade to the ground terminal.
