Does anyone know what this idiot light signifies? Is it oil temp or water temp or both? This light just came on yesterday and is staying on now. Will disconnecting the batteries reset the codes or does it have to be flashed??

 

These trucks has a temp light? I thought the CEL just came on?

 

I've been told , the sensor is behind (under) the alternator bracket.....

 

It is for high water temp, comes on at 241 deg. It most likly went bad.

 

Is it the 97 in sig?

By 97 E-series has
Oil and water are same lamp. Triggered by the PCM inputs.
Cannot say year of the F-series

Ahh.. so it's just for the E-series. I'm kina surprised how much is different on those compared to the F-series.

 

Didn't Rodney tell me just the other day , we had two,, T J & I were talking about it fri , we each have a temp guage , & a light,, can't see the other sender....

What does the lamp look like litup in the 97F? Water, oil, or both?
In the E its oil/water temp and oil pressure all in 1 Red combo lamp by 97.
97 E was the new instrument cluster, F was early SD

I have seen 2 sensors in IDI and 94.5 psd

Pictures? I have Pictures!! Its always a good day when I have the camera with me!!

Here are the sensors


Those are from my 97 F-350
The temp light is on the panel with the wait to start, water in fuel, and Fuel filter light.

Picts are worth a thousand words. That is proof that the lamp was combined
when body style changed. New instrument cluster.

Mine says engine temp only

 

The lamp says "Engine Temp". There is no symbol or indication. Im guessing the sensor went bad. The water gauge is reading normal and the oil temp is 160 according to the scanner.

 

Noob here...W/o trying to hijack the thread I have a "related" question....recently bought a 1993 F250 4x4 w/ 7.3 IDI turbo diesel w/ fisher MM plow to plow my private drive in Maine....

Its been starting and plowing fine (unplugged w/o block heater) while the temps have been between 30-45 degrees F and last night it was going to be in the mid-teens and had snowed all day so I plugged it in overnight....

This morning at ~5:45am
Put key in - let glow plugs engage ~30sec then they turn out - go to turn over and nothing... just the ENGINE TEMP light comes on....?

Is it indicating too cold or too hot?
the block heater "plug" is working

But it will not crank does not even try....Any assistance is appreciated as I could have burned that thing to the ground I was so pissed this morning,,, but it doesn't take long to cool off in Maine and I'm back to my senses

Bottom Line is:
I would like to know what cause/effect the Engine Temp light has?
Ex: does it disconnect the actuation/engagement of the starter?
only when engine coolant is "too hot" OR only when too cold?

Or is just my Starter bad - and "nothing" is happening when I go to turn over....

Thanks and glad to be part of the forum.

Well your temp light should have no affect on the cranking or starting of the truck. More than likely it comes on when you have the key in the crank position normally it just since you have issues now you noticed it. My guess is that your batteries are dead or you have a bad connection.

Also since your truck is a 7.3 IDI for more engine specific (later reference) you will want to post in the IDI forum one spot below this one.

Welcome to FTE.

 

Agreed.

Did some work last night - but was cold as *****!..... Looking like Battery or Starter - will solve or eliminate those (2) items Friday or Sat. morning....

Thanks to all.
