r/ToyotaPickup

Internet is all over the place with the answer. It's either 180 degrees or 195 degrees, some are 160, some 190, pretty much my only options after punching my truck in to parts sites. Parts stores have all of them in stock and say "exact fit" for my Yota.

Middle Tennessee here, normal cold/freezing Winters, hot/blistering heat in the Summer.

I just can't figure out what OEM/Toyota calls for, for my 22R.

EDIT::: MY ACTUAL PROBLEM IS THE COOLANT RESERVOIR KEEPS FILLING UP, NEVER EMPTYING BACK INTO THE RADIATOR. No leaks, Rad. Cap replaced today, old one was bad. Pressure tested system = good, no leaks. NOT head gasket problem, did a leak down test.

I figured I can throw a Tstat at it and hope for the best. Tstat is probably 13 years old from last timing kit I did.

Only does this "fills up reservoir" when taking a 20 mile trip on the Interstate. Running a solid 70mph for 20 miles, get home, reservoir is full. I take a turkey baster, empty reservoir back into radiator, now radiator is full, and reservoir is exactly where it's supposed to be, right on the cold line. SO, again, no leaks.

NEVER happens while puttering around town/getting groceries/gas, even though I may drive/start/stop at stores over a 1-2 hour period, Traveling less than 20 miles.

New fan clutch 6 months ago. I'm stumped.
