RE: [MV] Engine Block Heater for CUCV, temp switches

Stu, the glow plug controller works based off of time, and water temp in the
engine. If the water temp is below the setpoint, the glowplugs will cycle.
They do this up until the engine warms up. If its really cold, I think the
timer runs longer, but I am not sure.

I still don't understand how the system knows when to turn off the glow
plugs. Are the glow plugs heating air or water? If air, what is telling
system air is at right temp? What gauge in the dash? There is no dash
gauge in a CUCV other than the wait light.

There are 3 temp switches in a 6.2 block. All in the water jacket, NONE in
the air.

1- left head, is the sender for the dash gauge.

2- in the right head, is the low temp switch for the injector pump.

3- The glow plug control thermister is in a water port BEHIND the intake
manifold on the drivers side. It is in a small plate bolted over a water
port in the head. Since V-heads are interchangeable, the same port is used
for the thermostat/water outlet/crossover pipe in the front of the heads. No
need to drain the water to monkey with the manifold, making injector pump
access a little easier.

There is no cross-talk between the 3 systems. I guess you could have an air
bubble at the GP thermister, until you drive up hill...or R&R ( remove and
replace, not the GI jargon) the thing to vent the air out?

B) I like the manual glow plug system too. And I live in San Diego where we
might get a frost....2 times a year?
