Ok yeah that's what I thought. Just to reiterate is sounds like the pipes just kind of lay in there. So if one or both of them stick to the WP (perhaps due to the o-ring) as you are pulling it off then you could pull it out of the rear which means pulling the heads off to stick it back in on the rear.

The DIY article for the 4.4i I found is missing pics. I found some pics here on the block drain plug here, and a writeup for the 3.0 procedure here. I will just look up the procedure for the 4.4 on TIS.

According to the service records it looks like the last coolant flush was performed 09/09/05 when the Expansion Tank/Coolant Reservoir was replaced. So according to the Fluid Maintenance Guide it is a little bit overdue. Both drive belts were replaced 10/07/05, so I would think they should be good but of course I will inspect them more closely once they are off the car.

As for parts - looks like I will need:
  • Thermostat (11 53 1 436 386)
  • Thermostat Gasket/Seal (11 51 1 705 408)
  • Water Pump (11 51 1 713 266)
  • Water Pump Gasket (11 51 1 731 462)
  • Water Pipe to Water Pump O-Ring (11 53 1 710 048)
  • 2 Gallons Zerex G05 Antifreeze
  • 2 Gallons Distilled Water
Please confirm this.

I'm sure there are writeups all over this site, just search it and see if you can find pictures.
