Aluminum radiator question

[OR VietVet]

My 2001 Tahoe always sits at about 190 at all times. It did go to 210 when it was 108degrees one day. And I was idling for 30 minutes. I think it may still have air

After how much time? Did you just fill today or yesterday or how long ago?

Mines always been like that. I’ve done several Tahoe’s coolant change. I fill the radiator first through the top radiator hose then fill the reservoir tank, leaving the top off, and let it run till the thermostat opens. Then fill it right away once the coolant from the reservoir gets sucked in. And out the cap back on I also turn on all the heaters inside the Tahoe so the coolant circulates longer throughout the Tahoe. Hopefully getting the majority of the air bubbles out. I’ve noticed The ones like mine with a clutch fan. Run about 190. My brothers with electric fans runs about 210. In the middle. Ill take a picture of mine fully warmed up. I think your temp is still a little high. You may need to keep burping it. I just realized that my previous post made it seem like I had air in my system. Sorry for the confusion. I was wanting to say your temp was looking to high still. This is what my temp looks like at operating speed

It's sitting pretty at 190 ish it doesn't jump up at all and it's been over 100 here in Indiana. Very efficient cooler. And for the build quality and fitment and durability, so far it's worth every penny
