968 water pump kaput?
We going out for an evening on the town. Realized I forgot my phone right after pulling out of the driveway. Weren't around the block and returned. Noticed a wet trail leaving my driveway. Checked under the hood when I got in the garage. Sure enough, power steering fluid (dex3) was low. I had noticed that peppery smell when it pulled in after work. Had a leak in the past that I cured but simply tightening clamp on one of the hoses. Noticed since fluid on my garage floor from earlier...looked like it has some water in it.
Picked up some dex 3, but as I drove home the car started making weird noise, then my warning light pops on and I'm overheating. Luckily my neighborhood is hilly and I coasted home. Pop the hood and I can hear a hiss. Coming from the same side of the engine as the power steering rack...from the oil pressure sender?
Also I'm losing coolant all of a sudden...down about half and it was full about 2 days ago when I checked oil.
Here's a pic of where the steam was spewing from...
Steam coming out between the white and black surfaces on the circled item. It's this the oil pressure sender?

It's the heater valve.

Is there anything that can cause problems with both the steering fluid and the coolant?

Also, it seemed like there was still vacuum, as when I opened my coolant reservoir cap the hissing stopped immediately and all the steam came out of the coolant reservoir.

Any additional information? I was able to find additional information on this part, but it doesn't sound like it's failure would cause my problem. I mean, someone did say that coolant can leak through there when it fails, but could I lose half of my coolant in 48 hours?

Actually broke out my shop light and what I thought was the coolant level in the reservoir was not...my coolant seems to all be gone. It wasn't a few days ago. So I guess it was the valve and my coolant was all dumped. I put in an email to my shop to find out what they used when replacing my coolant a couple of months ago when they did some other work for me.
I read in another thread where a coolant dump can ruin your clutch. Anything I can do to mitigate any such damage, even if the coolant already dumped?

G11 and refresh it every 3-4 years before the pH goes up. (the FLAPS carry pentofrost nf (8114117 is 1.5L) around here but I always call ahead, ask them to visually check their stock and get that persons name to avoid a goose chase.)
G12 and 13 start at a higher pH which eventually make the plastic parts brittle.
coolant is slippery but the heater valve is not at the back of the head like prior models.

Ordered the all metal valve from 928 Motorsports. So I'll read up on the procedure for removing and replacing that this next week. Hopefully this will fix my problem.

Have you ever heard of this stuff? Protec? I see there's a German company called Protec that sells chemicals for cars...but I don't this product on their site.

I would flush it with distilled water 3x then use pentafrost nf.
mercedes and subaru coolants of that era are similar.
the silicates in the proper coolant scrub the aluminum oxide that form in the passages to keep the heat transfer at the optimum level. it is good for three or four years.

The heater core holds a bit so it is best to drive it twenty miles with the straight distilled water with the heat on then drain it warm.

'universal coolant' isn't.
