What did you do to your NBS GMT800 Tahoe/Yukon Today?

[mikeyss]

The fans turn on when the compressor turns on so check to see if its coming on.

My fans will cycle on and off with the A/C compressor running, it just depends on how hot it is. When I remote start in the morning and it's 50 degrees, the compressor kicks on and the fans do not turn on tight away, the compressor may even cycle on and off a few times before the fans eventually turn on. However, in the afternoon when I remote start it and it's 90 degrees, the fans come on immediately and often will be on high speed.
The fans will work with the compressor about 80% of the time, its just dependent on outside temps. I know mine is working correctly because I just fixed my a/c compressor and my system is working perfectly.

I wonder if it depends on the tune, or if your vehicle came with electric fans originally because on my 02, which originally had a clutch fan, anytime my compressor is on my fans are on. Even on cold days when the compressor turns on and off for defrost the fans turn on and off. Was yours converted to electric fans or did it come with them from the factory?

There are many fan settings that can be changed in the tune. One of the options is what ECT to activate fans while AC is on. I believe the factory temp setting is pretty high 190* or more. Which is why I changed mine to 140* so I don't have to wait for ECT to climb before the condenser gets air.

Aha. And now I need to have Justin do ANOTHER retune lol.

There ECUs are so awesome so many options for stuff. I never realized how effective the stock 2004 radiator is. Dropped in a 160* T stat and lowered the fan temp activation. Went from normal temps around 200* or more to hardly ever seeing over or into 180*s and yesterday my mirror was showing 99*.

Also I'm checking ECT from a handheld not the guess-o-meter.

Thermal wrapped intake cus it looks cool.

Installed my Bilstein 5100 shocks today. Let me tell you, the ride quality has increased exponentially. They have so much smoother quality than the worn out 200K OE shocks lol. Also the passenger side upper bushings were missing, found my mysterious rattle lol. Thanks for those that gave me input on which shocks to buy. I love the change it made!

I have some titanium header wrap that I used for awhile, kinda cool because it was gold like my Pewter paint so it matched. I took it off when I was messing with the intake tube and haven’t reinstalled it.

Installed Moog front sway bar links in the 05 Tahoe! Can't believe the difference it made. Still trying to smooth out the ride though. Next might be the body bushings and new control arms. I discovered they are SMV brand...

I wiped down all the black plastic on my Denali running boards roof rack they didn't have ultimate black so I used this
