I'm hoping someone can help me with a problem I used to wish for. ;) I
took a head-clearing drive this afternoon out a twisty mountain road
west of Denver.* Today ambient temperatures were probably 60-70F, and
around town and on the highway the car ran -- as usual -- somewhat shy
of 185 on the dial. But while driving on the twisties (2nd/3rd gear,
revs 3000-5000, 30-50 mph) the car ran especially cold with the temp
gauge reading more like 130 or 140F. This was true both up and down the
route. Coming home on the highway I was back up to normal, left of 185.
So... is there a tuning problem that would cause my TR4 to run
especially cool at higher revs? Or is this not a problem at all?
The car has a later TR4 radiator (no crank hole or long filler neck
anymore), aluminum sheet radiator shroud (general design inspired by Joe
Alexander), recently installed TR3 fan hub assembly (again thanks to
Joe) with yellow fan (TRF), recently installed 160F new-style sleeved
thermostat (Moss).
*no need for you to move to Colorado and drive up home values even more,
as the beautiful weather was more than offset by all the avalanches and
rockslides on my short drive.
