Oil temp questions?? 185° cruising to high?

jdeeg4276 · Oct 1, 2012

I've ran delo its whole life. Just questioning how hot I should be getting it while towing/driving down the hwy.

185 no towing and 65 mph down the hwy

220-250 towing about 60mph and pulling hills kinda hard. All stock engine besides the blue spring. Working on doing all upgrades all at once.

Thanks for info. Much appreciated.

185 sound fine, mine usually is about 195 or so, but the towing temp seems like a plugged up cooler.

I was thinking the same thing. 185* EOT is even a little on the low side, but 220-250* EOT when towing is a tell tale that something isn't right. Unless you're towing 20k lbs or more.

I ran 190 miles yesterday and my EOT stayed around 188 ECT was at 189 running amsoil 5w-40 with a bypass. No load just cruising ac on and about 70-75 mph.

That's cool at cruising. Loaded/towing you have problems. When you are towing, what are your water temps?

jdeeg4276 · Oct 6, 2012

My water temp is usually bout 20°( average) lower then oil.

Hell unloaded cruising around 70 my EOT is anywhere around 205-210 but but the EOT vs ECT delta rarely goes above 10* difference

Sounds like you need an oil cooler.

That's what I'm picking up on as well.

I wouldn't see why not a OEM cooler.... Need a coolant filtration as well

Flush the cooing system using the Ford procedure and additives. My advise is pay someone to flush it, because its a ****ty job. Flush it then replace the oil cooler. After that re evaluate your EOT and ECT differential. Ford recommends no more than fifteen degrees. Used to be twenty five degrees.
