Yeah, battery is fine.
I will check further on the crank sensor, but agree with you that having the codes pulled would be the best course of action. Will check a schematic on its location. I...

This car is way more advanced than my other cars including my 93 urS4.

Anyone know if a code should be present if...

Dave, do you have a pic of backside of cluster

showing which wires go to which of the three slots. CEL, airbag, seatbelt.

I pulled my cluster out to replace the ignition switch, and while I took some pics, they did not come out clear.

Dave, cant I just remove this piece and

replace with a short section of hose.
If all this thing does is bleed air, $107 smacks versus $2 in a straight hose, I would go straight hose.

Your thoughts please.

Unbelievable

Got everything together and all appears to function. Typical cuts and scrapes on the hands.

Got the whole fan unit out of car last night

and disassembled. Took about 3 hrs in all to get to this point.

Yes, the serpentine belt went on fairly quick.

I remove the tensioner for easier access and visibility.
Thanks for the insight.

The weekend fun I referred to will be the heater core replacement. This is the task I need to mentally prepare. ...

I already have your writeup downloaded on my desktop

Amazing how 6k miles or so tore/cracked up this belt. Not sure the brand as it was unreadable. I guess that I purchased one years ago in a larger buy from one of the big box online stores. Had...

Will go OEM

That had to be strangest experience driving a car for me at least.
Steam pouring out of the dash and being blown by my AC in the middle of summer.
Was like a dust cloud in the car.
Thankful it...
