[T3] Runs Great....but very hot...

[Keith Park]

Well, theres no way to know how hot it is unless you measure it, namely the
oil temp.

If the air flaps are opening, the cylinders and oil cooler are clean and not
clogged with dirt or mouse nests, the tin is all in place, the bellows is in
place and not torn, and the mixture is about right it really cant overheat
unless your crossing a desert or pulling a boat on a hot summer day.

Have I missed an overheating cause?

This is about T 3, 71, Std shift.     ...the one that had endless Fuel
Problems that seem to be now fixed by a hundred adjustments and tests,
unhooking Cold Start, Changing the Control Unit and so forth.  The Temp
Sensor in the Air Distributor is also unplugged.   If I plug it back in, it
runs kind of rough.

It's been mostly fine for months...except one thing...Idle would, at any
time, stay high for a while.  Then later, hot or just warming up, dip to low
enough to flicker the oil light. While driving it was fine.  It never
stalled.

The other day, on a hunch, I changed the Pressure Sensor...and now the idle
sits right where it should...no more highs and lows.
 Does that make perfect sense?

One problem left.   After maybe 20 or so miles, highway and in town, the
engine is really hot...hotter than it should be.

What's the list of probable reasons for the heat? (No...there's no rags in
the air ducts.)
