A small thing, but it dropped the temperature on my TD by about ten degrees
is to block the heater bypass. If you have a heater there are two lines that
deliver and return the hot water to and from the heater. When you turn the
heater off you essentially block the water from flowing.
However, if you do not have a heater (as I do not) then there is a single
water line that connects the two ports and water is free to flow through
this line without ever seeing the radiator.
A few of us have taken a block (we used a common copper cap a plumber would
use to terminate a line) and stuffed it down the hose between the two ports
for the heater. All of a sudden the water must pass through the radiator
(and the thermostat) resulting in a cooler running engine.
We have not noticed any problems, however, we have only had this adapted for
a month or so. Time will tell.
