Temp not rising above 150

Almost identical

Take your ball and go home.

lmaoooo

I’ll continue to drive and see if the smoking persists and where from

Sorry if I’ve wasted anyone’s time

Never feel like you are wasting our time, if it's got you concerned enough to ask then we are happy to talk you through it.

Yes, agreed. I had wondered this myself and better safe than sorry.

Are you reading the gauge correctly? The span is between 100 - 210 . Each has has an approximate value of 13.8 or round up to 15. Therefore 195 would be 2.5 - 3 hash marks below 210. Or close it's a guide not exact. It's a truck. Model design " C " is two wheel drive. A " K " is four wheel drive.
C1500, K2500.

Only one way to learn and receive guidance sometimes. Wasted time? I'm sure most, if not all, of us are getting on here and passing spare time. If one were to view it as a waste their time, they'd be free to move on to other endeavors and not reply.

Indeed. It's not as easy as it looks, because the gauge face was designed by a middle-school kid to look "pleasant" which causes the gauge to be TOTALLY MISLEADING.

Nope.

Look at the temp gauge. Low reading is 100. High reading is 260. That's a 160 degree difference.

But the middle of the gauge is not 100 + (160/2) = 180. It's 210. So the first half of the gauge represents 110 degrees increase in temp, while the second half of the gauge only covers 50 degrees. The higher the needle goes, the fewer degrees are between the evenly-spaced markings on the gauge face. This it totally common with temp gauges, but most (aftermarket) gauge manufacturers have enough sense to not use evenly-spaced markings on the gauge face.

The marks on the GM instrument cluster gauge do not represent an evenly-spaced amount of degrees. The gauge markings are screwed-up to look symmetrical and evenly-spaced when the temperatures they represent are not evenly-spaced.

Then you also have to add in the coolant temp sender in the cylinder head will have some wild temperature swings compared to the temperature at the water neck, thermostat where the ECMs sending unit sits. I have seen 20° differences at times and they nearly match at other times. Depends on the rpm and thus coolant flow and the load on the engine. When you are idling or cruising at low rpm, everything mostly equalizes. When you put the hammer down, at first the high rpm will cause the water pump to surge in output, pumping the block full of colder coolant and the dash gauge will drop like a rock, this likely forces the thermostat closed momentarily, then as the engine starts to heat up from all the waste heat of running at full power and full load the temperature will start to climb fairly quickly, then it will even back out at the new equilibrium, that is if the cooling system can keep up.

Ok, I didn't look at the total values, only the 10-21 range. I will do better. Thank you.

Meh, I don't know what you guys are talking about! I don't have any issues reading my Temp Gauge.
