Where is the thermostat for the T44TQ oil cooler

[Larry C Leung]

Hello List,

On a 1 hr highway drive both up and back in
this near 35 degree weather, my oil temp
barely made 80 C, and this was on the slow
speed (stop and go, spaced out a bit, on the
way to the highway). Once moving, the needle
was barely above 60 C, but definitely off of the peg.

So, I am assuming that there is a thermostat,
and wondered where it is. Anyone know?

If it is in the body of the oil cooler, then I might
as well replace with an aftermarket unit. Any
BTDT?

TIA,
