Waiting on my appointment with my speed shop to check up on the t-stat and now even the electric water pump. Thank you

Quite confident that the first two points you mentioned have a “check” against them, however the electric water pump, that I’m not sure of. Any idea how I can check of it’s health and functioning?

Will update everyone here once I figure out what went wrong.

Thanks buddy. Will check and let you know. Didn’t think about the radiator or condensor being blocked. I mean I can see the radiator and it seems clean. Gotta check out the condensor.

I had upgraded my thermostat not too long after My truck got supercharged, because during the installation of the supercharger, for some weird odd reason there was this huge shortage in the market on the availability of thermostats. I’ve had these upgraded thermostats before in my naturally aspirated 2011 Sierra and I could see a huge difference in temps, however when I installed it on this truck when supercharged...it did not seem to make almost any difference. The coolant temp needle bearly came below the 210 mark. I’m assuming the thermostat possibly too isn’t doing its job. Gotta check that too.

Like I mentioned above, I don’t have active shutters.

Ok thats a lot of technical points there. To answer your questions/suggestions and proposals; 1. Not sure on this, however I will be taking my truck to the speed shop soon to attend to the entire matter. 2. I’ve removed my air dam since 6 months or more because I, during winter, would go off roading and hence needed the ground clearance. However, what did change in the last week is that I got a 2.5” leveling kit...could that have possibly caused this? As in the combination of no air dam and a 2.5” lift at the nose, exposing more summer air to the radiator something? 3. I’m quite confident that both fans are running....over time if anything...especially once the engine hits operating temps of 210 degrees FAHRENHEIT ;-P And yes given the choice we wouldn’t leave home either...

Hey there....no I’m afraid not. The 2016’s, at least here in Dubai never came with the grill shutters.

Hey guys.... I've got a '16 Denali with a supercharged 6.2L engine and 8-speed tranny. It was a standard 2.9L Whipple set-up and I've had this set-up for about 2 years now. Last year everything was fine. Typical of Dubai summer, we had even seen highs of 125 to 127 degrees and the truck did perfectly fine. This year, we've seen highs of 105 degrees as of yet, however I have seen my temp gauge going up while it was only 94 degrees outside. I don't understand. up to 60mph, it maintains the normal temps of 210 degrees, however should I accelerate beyond, and I mean conservative acceleration, nothing aggressive from say 60-75 or even 80mph, the needle starts moving up and it goes all the way up to around 3/4 to the overheating mark, say about 230-240 degrees. Any body have any idea what this could be and what could my solution be? I've checked, I have no leaks and even my thermostat seems to be working fine. Perhaps a bigger radiator? What do you all think I should do? I look forward to your positive feedback. Best regards.
