my engine oil temp light,stays on,changed sensor,no fix,eng oil temp on scangauge is fine when driving on my 2000 f250,any help please.

 

hows your oil level? have you check your oil pressure? what temp is it at according to the scanner?

 

Don't mean to hijack but how hot should the engine oil temp get? When towing mine sees as high as 225deg. Regular driving is around 210.

 

That warning light is a combination Oil Pressure/Coolant Temp gauge. I presume the indicator light will come on when the water temp is very high or the oil pressure is very low. Do you have abnormal reading on either of these gauges?

Here is a pdf of page 8 and 13 from my owner's manual.

 

I see about 220 during the summer. Haven't monitored it while towing though....will add to my "to do" list.

 

oil level fine,170 to 180 temp,while driving in phx,az,have not,ckd pressure yet.

 

I see a max of maybe 195 in the hottest North Texas summers on my Scan Gauge. I'd be a little nervous seeing my oil temps that high. Are you guys with that high of a temp running the 203 deg stat??

BTW, I never new there was a separate light for oil pressure or coolant. I thought that's what the "gauges" were for.

EDIT: My 2002 doesn't have that. It has a "Check Gage" light that apparently replaced the one y'all have. However, I've never seen it, even when the fuel is low. I get the little fuel pump light when that happens.

From my Manual:
Check Gage: Illuminates when any
of the following conditions has
occurred:
• The engine coolant temperature
is high.
• The engine oil pressure is low.
• The fuel gauge is at, or near empty.

 

mine is running 210 normal, up to 235 towing....

 

So does anyone know at what point engine oil breaks down at? I live in sw la so I run rotella15/40 Dino year round.

 

So does the light stay on even when you first crank your truck? If so it may be a shorted wire like the alt light issue.

 

I am just running with the stock type Motorcraft thermostat (not sure what the temp setting is though...). I connected my AE on the way to work this morning (22 mile drive) and the oil temp averaged about 185 degrees with air intake temps around 60 degrees. I was surprised how quickly the oil temp would rise if I stomped on it for a bit. (Seems odd that the temps would climb that quickly with the volume of oil in these things.) When I got to work, I put it in park and held it at 2000 rpms for about 20 seconds and the oil temp quickly climbed to 192 before I let it idle back down to normal. At idle, the temps held steady right at 188 for a minute or two before I shut the engine down.

I've never monitored the oil temps when towing but I'll be sure to give that a try next time.

 

OE motorcraft is going to be a 195*, the 203* are special order, not even avalible from the dealer IIRC. I also am interested in the temp of oil brake down. but i will start a new thread for that!

 

Ford switched to a 192 deg stat several years ago. I have one in mine. It was done to reduce NOx emissions....
