Did you check all the components in the air heater assembly for what is malfunctioning ? I ask this because there are several things that could fail and prevent the heating element from getting hot. I would think the solenoid would have failed before the element.Did you ever use the air heater ? I ask because I dismantled mine. A sniff of ether is 100 times more effective than the air heater.

The heater from NAPA should be an acceptable replacement.
Still trying to get it out of the manifold without breaking anything. Doesn't appear to work when I did jumper it from the starter lug to heater.Have you unscrewed the heater and applied 12 volts to it so you can see if it is any good ?
I have seen the resistance coil break loose at the end and show open on a VOM. I have successfully welded them and returned them to service. The screw in block heater is easy to check for resistance or remove and submerge in water and plug in briefly. Those systems are not rocket science and very good, I have a 830 Case ag tractor with the 301 diesel which will start down into the 20's with no starting aid other than the air heater. Large capacity batteries, 1000 amps X2, large truck cables grounded right at the starter and a starter verified to be in perfect condition and those engines start. I read how everyone has trouble getting them going and that just has not been my experience if properly maintained.
