LBZ: Is this temp correct?

[racingctf14]

Now that it is cold outside(20-30 degrees) my truck will not get up to the same temp that it used to. Does that mean the thermostat is stuck open? Here is a pic of the temp gauge at its warmest point during normal driving.

Thanks in advance

Does it fluctuate,put the truck in manual and shift high get the RPM up hence the ECT up.

Is you coolant tank fluid level where it is suppose to be

I took my truck into the cold today. ~40*

Letting off the throttle coasting downhill my temps rapidly dropped to 185* like yours in that picture.

They rise to 210 in 30seconds or so if i get on it.

It's doesn't fluctuate at all unless I start climbing a hill and then it will get up to just under 210. I will have to check the coolant in the morning.

Thats what i have seen lb7's, lbz's and lmm's run. Your temp is normal.

My sons lb7 runs that temp all the time, only seen it higher when it was hot as hell outside.

 

[hondarider552]

per that gauge, actual temp is around 165-170*

my lmm runs that temp also when the air temp is below 40 unless i am putting a power joke to shame

265,000 combined miles between My LLY and LBZ tells me your temperature is right where it should be without a winter front in 20-30* outside temps.:thumb:
