mine gets to 210 when towing or hot rodding, thought about switching to a ten degree cooler thermostat?? good idea??

 

No, it does not matter how low you go on the thermostat,it'll work only until it opens the 1st time,then it'll get hotter,except for the winter,then it'll run cooler.

 

85 degrees here today. a/c on-70 mph on the highway, coolant temp never went beyond 192 degrees.

 

That's all fine & dandy for you all that aren't towing!
What temps are you seing when you tow?
Are you still running factory coolant(G-05)?

I'm towing at 80 degrees and it'll get around 210!

 

My Oulook monitor runs about 13-15 degrees higher than actual. I normally see 190 and my Outlook reads 203. Hope that helps......the Outlook reads high.

 

Thanks for all the helpful ideas, But Highstakes finally gave me an answer that's worth noting.

Thanks Highstake. My outlook reads 210 - 215 when my factory needle is standing straight up 200.

 

Air temp"s here have 100 or more for the past week and it will be the same all of next week. my truck engine temperature runs 200-210 with no problems.
Gosh, I love my truck.

 

Anything under 250F with synthetic oil.

 

Napa has a good 180 thermostat, looks like the factory one and works really good. Truck runs about 10 degrees cooler all around, I like it.

 

Thermostats don't open all the way when they open up. The hotter it gets, the more they open up. Mine runs 10 degrees cooler everywhere.

If I lived up north, I'd keep the factory 190, but I'm loving my 180 right now.

 

Exactly, the 3rd generations make a lot more pwoer then 2nd gens., and like stated more power = more heat

 

empty truck, the coolant temp needle is just below the halfway line, oil temp is around 210.
towing 10k lbs, coolant will go to the right of the halfway line, oil temp 230-250*.

 

I would have never thought that the oil temps on these CR's would be that high.

 

I've never seen more than 215*F oil temps on the '05, but I measure at the top of the oil cooler.

 

me too mike. at one of the extra 1/8" npt ports on top of it....
