I sold the truck, but the gentleman I sold it to was headed to the 7.3 adapter himself. He loves the mechanical advantage. Said it's the bulletproof option.
OK bismic and crew -
IT WORKED!
I hard wired the fan using bismic's instructions, and ran her all morning in some serious heat - and she never topped 190. Not even 191. Most of the time was in the 180s.
I wasn't pulling a load or anything, but just driving around warming her up I hit...
Errrr - that should have said "bismic and crew" - my apologies, bismic!
I'm not seeing how to edit the post, either - so it's permanent, looks like. My bad.
OK cosmic and crew: I'm going in. I have just a bit of spare time, and I need to move a buddy's truck in the next few days - so I've gotta get this thing going.
Just splice in a grounded wire to that royal blue wire, flip the switch and let the clutch warm up, and she should roar to life...
Topped off the degas bottle. Check.
Chased down the EGR and see this:
Is than an EGR ******? I see the harness hooked up. Do I need to yank the actual component to know if it is in fact an EGR ******? Can you tell from this pic?
bismic - thank you for your thorough and specific comments! I really appreciate your guidance. I'll see if I can work my way down the list and hit on something that makes a difference.
I'm not sure how to return to a stock tuning position, but I'm willing to give it a try if you coach me...
Darn thing is running crazy warm.
This is what I was running with a cab full of kids, and nothing else. At all. Seems ridiculous warm. Wasn't even an outrageously warm day. Mid 80's.
Hey bismic - thank you! I'll give that a go. I've got some time coming up next week, so maybe I can get in there and play around with that.
Let's say the fan doesn't come on - at all - even with the manual override switch. What's that mean? Time for a new fan clutch? Do I need special...
How do I do that?
I'd be interested in trying it....
I'm going to swap out my coolant filter today; it's been a little while since I've swapped it out, so I'm due for a new one. Just not convinced that a plugged coolant filter could keep it from cooling. It sure won't help, but I doubt...
