M38a1Cdn2, M38A1Cdn3 and M151A2 CFR range

There was never an authorized modification to install block heaters in any of the Jeeps. While it is possible that some military unit may have installed it, the likelihood is that the heaters were put on post-military. Most units did not have plug ins for the military trucks, and you could hardly plug a vehicle in while out in the field. Quite frankly, it would rarely get cold enough in Ontario or Alberta to need to plug in the 24 volt jeeps. They would start without a problem down to about -20. Here in Manitoba, that is a different story. Yet even here, block heaters were rarely installed in the old Jeeps. We did install frost shields on the windows though, although more so on the old 3/4 tons and duece and a halfs.

The installation of the hot water style pers heaters on the M151A2s were even an afterthought. They were originally delivered without.

I'll take a picture when I get a chance. What your saying makes sense.

Thanks
