Re: Help, cold TN1, (in snow)???
I'm confused here?
Your member info says 2006 Low Top Passenger van with seating for 10,
but the first line of your post says 2016 T1N?
Is your Sprinter a 2016 NCV3 or a 2006 T1N?
No T1N Sprinters (5 cylinder OM-612 in '02/'03 5 cylinder OM-647 om '04-'06) have been shipped to the USA after the 2006 model year.
If you do have a low top 2006 T1N Passenger Sprinter, you may want to get some
soft foam and fill in the 2 dash top ducts as they do add alot of cold air unless you
use the recirculate.
Since your Sprinter is a passenger van do you have the rear heater system?
If your Sprinter is indeed a 2016 NCV3 do you have the OM-651 4 cylinder inline 2.143 liter 2 stage turbocharged engine/7G-Tronic (7 speed) transmission or the OM-642 3.0 liter V6 engine with the 5G-Tronic/NAG-1 (5 speed) transmission?
My 2014 NCV3 170" wheelbase hi-top/short back 516 series (3500 USA) often runs a few degrees below 180 deg. F.
I get more than enough heat @ engine coolant temperatures in the 175-180 deg. F range.
I suspect that your not getting the heater controls and dashboard/ foot well ducts set up correctly.
I can easily make the interior of my Sprinter (the cab area only) uncomfortably warm with the coolant temp @ => 130 deg. F.
It's all about how you set the vents, and how much circulating fan you use, plus where you direct the most available heat.
I mostly put the blower on 1 or 2, the temp @ 72-78 deg. F with the majority of the heat directed at the floor/foot well ducts with just a tiny bit flowing from the dash vents. I keep the passenger side dash vents fully closed by the little vent flaps.
Either way, NCV3 or T1N, temps > 175 deg. F but < 235 deg. F are nothing to be concerned about.
I see no reason for you to mask off part of the radiator. Your Sprinter is probably running right
at the full open thermostat temp.
Close off the ducts to areas where there are no people, set your heater controls for the amount of heat that's comfortable for you and your passengers (if any) and you should
be able to stay toasty warm.
I had a 2006 high top/short back 158" wheelbase Sprinter, and once I plugged the 2 dash top
vents, I was toasty warm and the temps were controlled nicely by the on board climate control
Hope this helps,
