Some pretty fart smellers on here!
Sucks about the cranking issue. Did you you replace the FPR on the intake? IIRC, there's one there.

Yes, the OE radiator has the restriction in it. More info here:
2006 Tahoe Cooling system running to cool. 5.3L Flex
I got a 2006 Tahoe 5.3L flex that needed an engine. found a remanufactured (z code engine) had installed with new water pump, radiator and thermostat ( have replaced 3 times wit factory 178 degree stat). Now the engine runs about 165 to 175 on the road. When idling it will get up to about 210...www.tahoeyukonforum.com
Someone on the forum used a part from a TPMS sensor, I think it was, to make the restriction for an aftermarket radiator. @kbuskill maybe?

I think that ended in 02 or 03 but I could be wrong, let me go look.

Sweet thank you! I will scrounge around and see if I have an old TPMS laying around.

The radiator should be here today and the oil cooler lines already arrived, I might get started today since I get home early. I dug through my parts stash and didn't find an old TPMS sensor but then luck struck and I think I have a TPMS sensor going out because the service TPMS message has popped up randomly a few times this week and I know my tires are good because I overfilled them Saturday to 40-45. Also, the message is popping up after 10-15 minutes of driving when the tires should be warm and the pressures up. I'll wait until the radiator has been tested for a week or so before I get the TPMS sensor swapped so I can tell if I need a restrictor or not.
Lol lucky to have a TPMS sensor going out. Said no one ever.

Gotta look at the bright side lol. I'm about due for a rebalance and rotation as well so it all works out in the end.

Radiator delivered, for some reason, I am very nervous about its shipping condition

Swing by any tire store and I bet they'd give you one or two dead sensors for your science project.
Definitely consider the Accel 9070C wires with 135° Boot. These have been flawless operating right next to my ARH Longtubes. Very happy with them.

AFAIK, the TPMS system has a safe operating range. It doesn't just report the pressures, but also if one sees a minimum or maximum. With the tires overfilled, perhaps the pressure in one or two met the high pressure threshold once it was warmed up?

Actually, it looks alright but I didn't get a chance to open it up yet.
I thought about that, and I will if mine turns out it's not going bad. IIRC I have replaced either 2 or 3 of the original sensors so I have at least one that's really old.
Those are super nice and one of these days I'll get some.
I guess I hadn't considered the overfilled possibility but I doubt 40-45 would trip it since the tires can be aired up to 51 and I have filled them to 45 or above before when towing. IIRC I have had either 2 or 3 sensors replaced since I bought the truck so it's about time for one to die anyway.

It's not what the tires can be aired up to- the sensors have no idea what tire is wrapped around the wheel. The Tahoe is programmed to see XX psi in the tires (32?) and allow a range below and above that before it'll trigger a warning. Actually, with a Tech2, you can change this allowable range if you're running tires capable of higher pressures so you can air them up for towing and not trigger the warnings. A simple test would be to start with them aired up as-is with no TPMS warning, then fill one up to 51-55ish or so and see if the light comes on. You might wanna do this after a short drive to ensure the sensors are awake. Otherwise, they might not register. Even then, there's a latency period before it reports.
Not saying you don't have a bad sensor. Just nerding on the tire nanny system.

This. I'm not sure what the high side is though. I run all of mine at 40 psi. IDK if they would gain 5 psi in the heat or not.

On the Denali or Avalanche? I found 34-35 to be my sweet spot for "over-inflation" on the Tahoe. More than that lead to noticeably higher wear in the center of the tread and, of course, harsher ride.
*Edited to fix auto-incorrected "thread" vs. "tread". Slight peeve. Thank you for your time. As you were. G'bye now.

Both. Any less and I'm wearing the outside edges of the tires lol

Could be driving style or just brand of tire. Whatever works! At least you're conscious of it and watch your tire wear.

It's the OEM style Bridgestones. They like to wear the outsides. It's worked for me for 150k miles. I think they have more of a rounded design than other brands

I got the radiator in and oil cooler lines hooked up. Also changed the oil with nothing of concern to note in the filter or on the plug.
Really pleased with this ColdCase so far the welds look great and in addition to the oil cooler it has a trans cooler built in. For now the trans cooler will be capped off but in the future it might become the power steering cooler.
On initial startup it needed a 7th quart of oil to show full on the dipstick and at least an extra gallon of dexcool to fill the cooling system. I also noticed on initial startup oil pressure took a good 30seconds to get above 20psi which is probably due to filling the cooler and lines.
