hi Luther!
sorry if i wasn't clear enough; temps come up fine with regular #2
fuel, but not as fast (or not at all) when running a high concentration
of BioD which we do most of the time.
(like i said below, we've already switched out 'stats a couple of
times just to check them and verify that they were opening at proper
temps; 'stats aren't the issue, and that's also supported by the fact
that op temps seem normal when running #2.)
cheers/73!

You need a new thermostat if the temp takes more than 5 minutes to
reach 80-85C. Every Benz diesel that I have driven (with a new
thermostat) has reached 85c within 2 miles of home at 30-40mph in
sub-freezing weather.

only slightly related; what kind of operating temps are you guys that
live in real cold seeing?
here where temps rarely get much below the 20s-40s this time of
year, i still don't often see the coolant temp indicate anything
above 80C until it's been on the highway at speed/load for many
miles. (i've already played with changing out the thermostat to units
i've verified are opening at the proper temps.) i'm sure this is
exacerbated by the fact that we're running almost pure BioDiesel
almost all of the time as we can see the temps come up quicker and
higher when we have to run #2 instead of B99 on road trips, but i can
run around town all day and never see the coolant reach the normal
area on the gauge even when temps are into the 50s and higher. FWIW,
the car starts fine on a single glow cycle, but (no surprise!)
definitely runs stronger when warm.
i know some veteran diesel-heads used to be seen with radiators
shrouded or grills even completely blocked in the cold to keep temps
up where they're supposed to be; what are the thoughts regarding
doing this with a 617 turbo-diesel?
cheers!
