Temp too low The temp on my ls1 is always at the first quarter of the temp gauge, sometimes only 1/2 way up the first quarter. it never goes past that. Does this mean my T-stat is stuck open, or is that how it's supposed to run?
when it's getting good airflow and the engine is at low RPM, it sits 1/2 way up before the first quarter. when i drive hard or in traffic, it's at the first quarter.

Mine is pretty much the same way. Only goes 3/8 way up in 90+ degree weather in traffic. I thought the gauge was broke till I ran it without coolant and it went up quick. I am glad it runs cool but takes forever to get heat in winter/cool weather.

my old LT1 was always between the 1st quarter and middle.
Is that the way LS1s are supposed to be, or should i get a new t-stat?
A stock LS1 with a stock thermostat should stay around 198-210F at operating temp.
You might have a bad thermostat, or you might have a bad temperature sensor. The gauges aren't 100% but they should read a little less than the 210F mark when warm.

How hot is the air coming out vents with the heater on ? It should be hot enough that with it on as hot as the controls go , You get too hot in about 2 min with the temp outside around 50deg far .

I'm not gonna lie, it could be a little hotter. Also it takes a long time to warm up.
