Normal Operating Temp

Lately I have noticed when pulling uphill temp rises rather quickly... Then when I get on flat it levels off. I have notice Top Rad hose collapsed after shutdown. Temp runs right aound 190-195 when pulling uphill. Is this normal??? Always levels out at 180 on flat.... This all started last week after I ran front tank out of fuel.... Did not have any problem getting stated back up... Does this have anything t do with it????

Thanks for any help....

I can't think of anything that would tie the two together. So it's only changes 15 degrees total? Doesn't sound too bad. Is the radiator full, (not just the overflow bottle)? Make sure it's cold when you check!

The factory thermostat was a 192* I put a 180* in mine just for pulling.

Unlike other's on this board I am not a stickler for oem thermostats. I'm running one from Napa. Been in there for 2 years with no problems. When I'm loaded I have a 70's wood camper (11 1/2 footer) on the back and an 18 foot jet boat behind me, so I chose to lower the temp a few degrees. I pulled this setup in 110 degree weather down in Arizona and Nevada with the A/C on, and never overheated.

I have tried a 180 from Advanced and found that I barely got over 120 degrees.... Does the Napa Tstat look like OEM??? I know aftermarket Tstat has a built in bypass...
WIll have to check out NAPA Tstat... and Thanks for the info...
