So I just put in 2 new Oem stats, coolant is testing good. What am I missing. The other day it was around 40 degrees, I started the truck and I got distracted and it idled for at least 15 minutes, when I got in the truck the needle barely moved, it took another 10 min of driving for it to come up to temp. I don’t remember my last lly taking this long
Truck takes forever to warm up

I can start mine up and let it idle for 10 min and get in and have some heat but the needle won't move. It hasn't been very warm here so they are going to take alittle to warm up...
Sounds like my stock LB7. You basically have to drive to get heat. And my built LB7 will actually cool down if you're not driving. It can be up to temp, but 10 minutes of idling in 15°F weather and it'll drop off the gauge.
I think that's why GM went to all the work to do the high idle stuff where it loads up on the torque converter in the later year. Only way to get heat without moving.

Even my LBZ doesn’t heat up that good. High idle fine, but without it you’re lucky if it’ll defrost the windows in 10 minutes.

use to let my lb7 idle in single or teen degree weather for 30 min before work. it would barely be blowing some heat by the time i get in it. moved to warmer climate and i dont have this issue anymore :roflmao:
going to work in single digit weather if i let off the throttle and decelerated it would start cooling down. said **** it and moved to warmer weather also 
now i have to run low temp stats and it still wants to get too hot in freeway stop and go... you never win :roflmao:

you could do like my buddies with company trucks do. 2nd or 3rd gear, wot, rev limiter bangin and you get heat REALLY fast
Let mine idle long enough to scrape ice off if there is any, then just drive it. Screw waiting on heat, that's what seat heaters and gloves are for
Yep, I have become addicted to heated seats. Makes me wonder if heated steering wheels are just as nice?
I can't bring myself to do that to my truck or Suburban, but in my Pontiac, I start it and GO. When you pay $2k for a car (and can easily get more for the same), suddenly the guilt of hammering a cold engine goes away. And boy do you get heat quicker that way :woott:
It has all been said previously. My LB7's NEVER warmed up (and produced heat) without the high idle and the winter front on both the bumper and grill.
Or power brake it
That should put a little heat in the transmission which in turn will help heat the coolant
I've draged the brakes before to load the Engine when I don't have a trailer on it
Id take heated wheel over seats any day. Though it was a silly till I had it haha
