I don't know anything about your supercharger kit, but I would assume it uses an air to water intercooler setup?

If so, have you verified it is full of fluid, and that it's radiator is clean and clear of debris?  Is the electric water pump for that system working?

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?

Sounds like a stuck t-stat

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

 

Thank you

If the cooling is not as good as before, it does suggest something has changed.  As others have said, check for gunk in the radiator/condenser/intercooler and verify your electric pump for the IC is working correctly.

 

That said, you will see huge improvements with a couple of simple changes--change your engine thermostat to a 180 or cooler (even a 160 in your situation would be fine) and tell your programmer to do this with your fans:

These trucks have good cooling systems, but they purposely are not "turned on" by GM until temps are pretty high for emissions purposes.  In your ambient temps, with a blower, it's silly to try and live with the small margin for error the factory gives you.  Those two changes alone should give you big improvements as long as you find/fix anything mentioned above.

    • I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.
    • I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?
    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
