Installed a new all aluminum Cold Case radiator in my 06 Sierra 1500 4.8L and I’m having trouble getting up to operating temperature in the normal time frame. I would think this will especially be an issue in the winter, but I’m in Texas so winters are no exactly terrible. Is this something I should be concerned about in the long run not reaching op temp on the majority of my drives?
Getting my temp to the 200 degree standard operating temp will take me about 40min of non stop highway driving while the fans are running with the AC on. My temp will climb to the 185-187 thermostat opening fairly quickly 10-15min but as it opens and the fans run, it is just too much cooling for it to ever reach op temp in a decent time. Also if I keep my fans off, and it does reach 200 degrees, in 15-25min, once I turn the fans back on, the temp will drop to 185-187 within 5-10min.
I know this radiator was a bit overkill for my stock application, but I wanted an aluminum rad to not worry about leaking issues in the future from plastic rads.

I have a 2014 Silverado 5.3 my ac works great when it’s not really hot or early in the am. But later in the day it has problems when the cooling fan kicks in high speed my ac compressor clutch disengages. And when it kicks but down in speed ac clutch will engage again it will continue to does this up and down routine. What is the problem ?????? Freon is good no leaks works great other then when it’s above about 86 degrees outside. Also the truck is not over heating havnt seen it over 210

ive looked high and low with no luck, so apologies of this is directly cited somewhere.
The plastic grooves/housing where the blower motor twists into place under the glove box, are brittle and broken. Therefore, my blower fan will not stay in place.
Is that plastic housing or assembly core sold as a stand alone part? Trying to figure out a way to get the blower motor secured without duct tape or something else.

Bought my 2020 Silverado RST almost a year ago (12000km) and this summer started noticing a whirring noise as I accelerate with the AC on, it doesn't happen when the AC is off. Dealership says its normal and its because its under load (been a hot and humid summer), another post here had a couple other people experiencing it but its over a year old so wanted to see if anyone else has/is experiencing it. Did any parts get replaced? Did it help?
The dealership said to keep an eye on it and they would replace the compressor if it got worse or if it continued when temps drop but if its normal function then that likely wouldn't help. Won't lie...i'm not impressed with how loud it is considering its a 60k truck.

I am just starting out to repair the AC on a van I bought from a neighbor and the air conditioning only blows out of the defrost and a little bit out of the floor. The system is charged, the blower fan works on all of the speeds, I just don't know where to start and the internet has nothing that will do me any good for my specific vehicle, which is a 1999 GMC Savana 3500. I was just curious how to resolve this quickly and in the cheapest way possible before I tore apart the dash and got in over my head. Any tips would be greatly appreciated. Thanks.
