Question for you guys on whether I should take this as expecTed cooling performance or dig deeper.
Preamble: 65k miles / 10k hours on the truck. All original cooling system hardware as far as I know, but I think the hoses were replaced when Customs had it because the hose clamps were all non OEM when I bought it. I have flushed the system and replaced the DeathKool. Rad looks good. Prior to yesterday I’ve never seen the temperature gauge move off 210.
The trans is a fresh GM Reman. It has the OEM tranny cooler in front of the rad.
The truck is lifted and 35” tires bring my effective axle ratio down to about 3.3.
Yesterday, while doing a sustained climb on a mountain road, she went up to about 225 on the engine temp and 219 on the trans. Conditions were about 90 degrees F and the AC was cranking hard. I was climbing in 2nd gear ~3500 RPM ~ 60MPH and probably about 75% throttle. As soon as I crested it cooled down to the usual 210.
So, should I be concerned? Considering the lift and tires I’d say my truck is working harder than a stock vehicle, but not as hard as someone towing a trailer.
Thanks for reading, and any advice offered.
