Temp gauge fj40 1967.

[cattrainer]

Hello,

What should a normal coolant temp be with relation to where the needle normally sits? On the first line or better than half way to the second line, I am talking about the two lines between bottom cold and top end hot. Is there a known exact temp each line represents? I replaced original engine with a 2F, I did use the original sensor from old engine.

Thanks for the help.

The owners manual says something about"the needle should be between the lines under normal circumstances."

While gages are not accurate from truck to truck, they are usually very repeatable, meaning that if it always runs at 2 needle widths above the first Mark, and then suddenly is running at the top Mark, something has changed causing it to run hotter.

Thanks, My temp runs 2/3 way between the needles and seems to stay there. I am just getting this fj40 going with different engine and fixing all the electrical and wanted to make sure of normal. I had a fj40 30+ years ago that i put a small block and i am now starting over with with this 67 barn find, so my learning/remembering is kind of steep.
