Different engine temp question, I've searched

With my 2.25 my "normal" operating temp was around 3/4 of the way up the normal range of my Series III. Has anyone ever measured at what temp the "Red Zone" on the guage is it? I am now running a Daihatsu diesel with a higher temp thermostat so it appears I climb to high temps under load but since this motor runs a 82 or 88 degree celcius thermostat it is tough to tell vs. the 74 and 82 degree rover thermostat. I'm still using a rover sender and rover guage. Do the infrared non contact temperature readers give pretty close readings if I just point it at the water outlet or top of the radiator. I suspect the Diesel just runs hotter under load, during easy going driving it stays bellow where the 2.25 ran.

For gosh sake put a real tempurature gauge on the thing. Egauges.com has VDO gauges inexpensive with numbers to track temps. I believe its rather important.

Sounds like a plan.

Anyone sure of the thread size for a series sender?

Murhpy Swichgages are nice too, and they have a manually set switch that grounds - can be used to activate buzzer, light, or both. more expensive though.

Confirmed it with a new sender, 5/8-18. The sender at Egauges is part #323-026. Also shot some temps with an IR reader. Half way up the series gauge driving around town the water outlet base is about 150 degrees, after a highway run 190 degrees, inlet pipe of radiator read 200. 200 would correspond with the beginning of the red on a series III gauge. I ordered the 250 degree VDO guage #310-105.
