Hey guys,

went for a ride and was sitting at a light and I could smell antifreeze, I became concerned but temp looked good. I was hoping it was another car leaking antifreeze. light changed and so did my temperature Gage, started to climb quickly. I turned the heater on to help reduce the temp but no heat. I started to sweat, I was only a couple of miles away from home so I went for it and drove home. Just as I got in my driveway idiot light came on and temp was at about 10 O clock. shut it down waited a while until it cooled filled with water and low in behold it was pouring out of the HCV. Ordered 1 and will be here on Wednesday. I miss my car already!!!

I better do the same. I can see mine going while making the trek back form PA. Perhaps I'll have Pete install a new one so I can rest easy.

I bought a chrome plated metal one...I don't see it leaking for a very long time.

Yeah, these things are cheap and easy to change, so I say change yours out if it has been on there for 60k miles and then keep the old one in the car as a spare. Belts, cam tensioner inspection, HCV... Some things just need to be on our schedules.

What is an HCV?

Heater Control Valve - that tiny container made out of plastic which some brilliant Porsche engineer decided to place right above above and inches away from the hottest part of the engine - the exhaust manifold [img]style_emoticons/<#EMO_DIR#>/dry.gif[/img]

Flash's heat shield (sold by RS Barn) will shield the exhaust heat from the HCV. I got the metal one XRAD mentioned, plus recently installed the heat shield. Nothing like a belt (ooh, painful choice of word when you're talking 968's [img]style_emoticons/<#EMO_DIR#>/ohmy.gif[/img] ) and suspenders...

Hey Guys,

were you get the metal HCV?? I ordered the OEM from Pelican, it was only 20 bucks so I bought 2 of them. I asked them about a metal one but they said they dont have anything like that.
Just came in today going to install it tomorrow, cant live without my 968!!!!

The metal HCVs are extremely rare nowadays. As far as I know they are no longer being made from metal. I suggest going to one of those spares shops were everything is a bit dusty and the smell of gearbox oil hangs in the air. Those kinds of places are bound to have old sotck lying around, and you might get lucky on a metal HCV.

Also do a search here on the forum, there are a couple fo threads discussing the metal version and it's part number.

I think it's either an Audi or a VW part you can still buy from those dealers [img]style_emoticons/<#EMO_DIR#>/huh.gif[/img] that fits and functions exactly as ours does.. but yeah, do a search here and something should turn up.

four things i don't like about the metal one:

1. you can't see the thing working, so when you have a problem, you don't know where it is

2. the vacuum port is not a direct fit with the oem hose and an adaptation has to be made - i hate vacuum leaks

3. a metal valve retains more heat - this asks for internal failure where the rubber meets the metal

4. the hoses don't fit quite right, making "on the road" repairs complicated

i'm not saying it won't work - i'm not saying the plastic one is a great design - but, given availability and the issues above, i'll stay stock on this one

metal ones harder to come by and do not fit directly, can;t remember where I bought mine

Thaks for the info,
Nice Pic Xrad!!! I do very well with pics. I can see you have to do a slight modification but nothing to major.
Im going to put the OEM in for now and try to hunt 1 of theese metal ones down.
I also had read that Pete from the barn has a sheild to reduce heat, Im going to give him a call and ask him if he has any, also I want a set refurbed cams for my shelf.

Thanks again

I keep a spare OEM plastic one in both cars (along with spare relays, belts and in one car a water pump* [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img] ). I like to have a few things on hand in case something goes out and the one car it probably will. I figure the first HCV lasted 13 years the plastic replacement should as well so that's what I used in both of mine, plus I think the flow pattern in the plastic one is straighter.

* at least I don't carry the spare radiator, fly wheel, clutch and power steering reservoir anymore. [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Wow your worse than I am HAHA!!!
A spare waterpump sounds like a good idea!!! I think I will get an OEM, I have read alot of Horror stories about the remanufactured ones.

Here is a pic of my broken HCV
all fixed and back to normal

Also wanted to add while repairing the HCV I noticed a small pool of oil by the oil filter, I always noticed a faint smell of burning oil. I cleaned the oil up and no more smell. Its tough to see in the pic but I did the best I could with it. Make sure you do a good clean up after an oil change. The problem is that I could never see it because the HCV was in the way. I am going to be more cautious on the next oil change.

Just blew out my heater valve yesterday afternoon in traffic...so much for a day at the lake. Instead it was an evening of getting my car to the local shop. Good times. At least the damage isn't too bad and I should have it back up and running for the weekend.

One of these days I am going to become mechanically literate and try to fix something myself. It seems that I could save myself some cash in the long run...

That is one of the easier repairs, and good place to get your feet wet.
