Heater control valve how to?
Does anyone have a "how to" on how to change the heater control valve? How about some pictures at the very least? Trying to figure out exactly where this thing is and how to get to it to change it.
Thanks,
Chuck

Karl being the experienced mechanic aficionado that he is, didn't mention that on the 2.5 liter cars the HCV is a bit aggravating to replace, due to the limited space that surrounds it.
Be very careful not to lean on the speed reference sensor plugs while accessing the HCV hose clamps. I found it easiest to sit on the strut towers to have better reach. It's also tricky getting the cable clamped on the new HCV. You need to fiddle with the temperature lever in the center console so that you can see the metal clasp and undo it.
COVER THE CLUTCH INSPECTION HOLE to keep the metal clasp or other items from falling in there!

As someone who recently did this, I am give some tips. PM me. Oh, and I don't know if this is standard, but my HCV was actually located along the side of the engine and NOT over the bellhousing like earlier models. I don't know if this is a custom mod the PO did or just something that is different with the S2 vs. earlier models.

On the 968 the HCV is over the oil filter. I assume it is the same on the S2?
It is no fun to change it in that location, you need to remove the oil filter to make room. But it shounds like it is much easier than the early car location!

The trick is to assemble the valve and it's hoses off the car, then install this as an assembly. Use the old one as a guide to get the hoses in the correct orientation. I was able to reach the clamps with a 1/4 drive ratchet and extensions. A long screwdriver would have worked just as well.

HAHAHA, i guess i am just so use to my engine and car being in pieces (or having missing peices), that i forget that there are normally things in the way...
Like Luis said, it is kind a pain to get to, unless you have the intake manifold removed.
