Shutterstat Questions

Richard, there isnt a removable plug on the end of one of the heads? Even a large one could be reduced for a sender. There is a 3/8 or 1/2" pipe plug on alternator end of upper head. Probably need a good impact wrench and a good allen socket to remove though. I would like accurate temp at head since overheat can crack them.

I asked about some of the locations you're talking about last year when I had the bus in for service. Some were not suitable for the sender (not enough depth) and others I think would have read oddly. Can't remember the specifics, but it was recommended not to use them.

There are plugs on the front of the heads to,you can install engine heaters in I don't see any reason a gauge would not work,the best location is the T-stat housing

Pretty much the rest are inaccessible.

You can always use the temp gauge like on air cooled diesel engines

We really liked our rad shutters but they never really worked, as they were beyond worn out so we removed them. We are looking to put fasteners on the rad door to accommodate a winter front in the case of deep cold temps.

My understanding is that the actual temp in different parts of the engine will not be the same. The general place to take the temp is at/near the thermostat housing, and all the ports there are occupied.

I'm sure that it's possible to stick the sensor in some other opening into the water jacket, but there's no telling if the temps there will be 'normal' even if they are reading higher/lower than expected.

In the end I might pull the existing sensor and temporarily put in an aftermarket one to use another gauge for a bit to check the accuracy of the dash gauge.

I think it's always a good idea to do a boil test if & when the sender is out or diagnoses of a sender in question. Thermostat in water on a flame with an accurate immersion thermometer will tell tale the accuracy of a sender - w/o question.
