wrench light

Hey I've got a wrench light on in my 05 powerstroke. I have it fully deleted and the oil cooler upgraded. Had it done last year and mabey 20000 miles ago. Also had a new radiator put in three weeks ago. I had a radiator shop do it. They also flushed the truck at this time. I've had new heads put on and arp studs. The truck is not going into limp mode and the light only comes on after work on my way home. Nothing is showing up on fords end when they scan it...truck runs great and strong and my deltas are right at the 15 degrees mark for oil and coolant...boost is running normally. I've noticed it trips the light about the 15 mile mark on my way home...I am just about to dump this truck because I'm sick of dumping money into it. This light better be something simple...what ya'll think it is?

Re: wrench light

Re: wrench light

To me, all of the trmps seem way too high. Mine runs around 188 to 192 ect and eot 7 to 10 above ect. I have a 03 Excursion with the small water pump. I too replaced the cooler and water pump, but I also have a coolant filter. When they did the coolant flush, they may have loosen up sediment in the block.

Since the radiator is new, how old is the thermastat?

Re: wrench light

Mine runs hot too, I have good Deltas. I can't figure out why mine is so hot either.

Re: wrench light

Your oil cooler is plugged, again. The wrench light is a safety built into the latest PCM flash calibration. Anything over 15* deltas it will turn the light on.

Re: wrench light

Ya it may be plugged again. The thermostat is a month old and the pump has 20k on it. I'll have to check the oil cooler. Even with upgrades and bulletproof I'm fighting this thing...times like this makes me miss my 5.4...less power but sure didn't have half these problems...lol

Re: wrench light

What does anyone think of bypassing the oil cooler with a B&W super cooler? I can put a cooler together and route the oil lines cheaper than 2000 for a bulletproof one. I'll have to add remote filters for the oil but has anyone done it? Just wondering...
