I did this job on my Catera without replacing the HBV and simply bypassing it which means you loose your heater. for me it was no big deal but ur in the the colder climates you might want to replace. Either way this is what i did, and im sure it wouldnt be further off on your rig.
you need.
Long flat head screw driver
2x clamping pliars
3" long 2/12" inlet stainless steel pipe.
Torx bits
First remove the Windshield Cowl and wipers to make room.
The HBV is directly behind the engine on the passanger side It has 4 hoses connected to it. 1 hose on passanger side and 2 on the driver side. then a smaller hose (not sure what its for,presurizer?) that goes to the top of the HBV Remove this. I also had to remove one of the tubes from the plenum as it was akwardly in the way.
With a pair of clamping pliars, clamp down the metal retainer bracket to the single hose on the passanger side (one thats easiest to get to) and remove the hose.
; I found it best using a stepping stool and also climping on the top of the engine,
Now, using some force, pul up the entire HBV unit from the bottom and lodge the flat head screw driver between the engine and cabin filter area to hold the unit in one place while u work on it.
Remove the remainder hoses.
There is one hose that goes from the drivers side into the cabin of the car. This is for the heater. I stoped it up using a wine cork and the orig. metal retainer
LAst take your stainless steel pipe and fit the remaining hoses to it... Walla. You got a HBV that cost you under 2 bones and will out last the stock unit!
