Nope I was loosening it the rightway according to the tech book. Was going to use 2 36" pipe wrenches but both the jaws together were to wide. No i'm trying to be careful to not wreck anything. I just don't like to explain broken things to the wife. Because I get the why were you messing around with it in the first place speech and it goes on from there.

We have more and more in common EVERY day!

Finally got them installed.
First impressions:
Normal was 14.2-14.4 volts
Now is 14.1-14.3 volts
Temp really never changed.

Only took the tech and I about 40 minutes.

One thing to anyone. Take the cam positioning sensor plugs off. We nicked the drivers side one taking the shroud out.

Belt fit perfectly!

Cool, Lars - Looks like you won't have to fiddle with the idle RPM for battery charging (or were those voltage readings at "cruise" RPM)? If so, then at idle with lights and accessories on, you could be at a pretty low charging voltage.

I'll be interested to know if you can "feel" any power increase and if you see any gas mileage increase. Let us know!

Ok I will add this with everything normal and at idle now and I turn the parks on or apply brake it drops to 13.7 then come back up in 2 or 3 seconds to 14.2. Turn the headlights on and it goes down to 13.5-13.6 and recovers to 14.1.

Its about 55 today and the cht was at about 201-204 cruising at about 70 mph. Came home and it stayed at 200 sitting for 15 min in the driveway.

And of course you do a mod and either its percipitating or you're sick. Its just down pouring right now. Even w/o customs and running at stock, it felt like it had a little more pep.

Those numbers all sound fine to me, and I'm sure you think so too. Too bad you don't live down here. It's 96 degrees out, the sun's shining, slight breeze out of the west.... This is pretty much what you get, mods or not!

I thought for $30 it was well worth the tech doing the procedure and having "all" tools available. I paid it eventhough I work there and the owner said I didn't have to. It was pretty slow today due to the rain.

Heres a pretty good price for the e-fans and udp from troyer.

Ok quick ?

What's the min volt needed on these trucks when running?

The only reason I ask is on saturday I was going through a car wash and noticed the voltage dropped to 12.7. Truck was in drive and head lights were on and I was idling out during the "dry" cycle. Rpms? Didn't have this pid on. Cht was at 205.

12.7 sounds low to me. I think I'm always above 13, even in idle with the lights on. You MAY want to raise your idle a bit - maybe 50 rpms or so?

I don't suppose the car wash got the pulleys and belt wet, so they were slipping? I know on my Honda, this can happen when I go through a deep water puddle.
