 Posted: Sat Jun 13, 2015 7:55 am Post subject: inline valve for front heater core |
 |
|
I have been acquiring parts for under the dash and planning it out for years  . We are heading to Vancouver Island for a summer trip in two weeks! There is no way I'm going to attempt this now. I'm searching for some threads that talk about putting a valve in to shut off circulation from the heater core. I cannot seem to find them. Anyone remember these and perhaps the titles?

The Vanagon came with a shut off/control valve from the factory which was operated by the lever on the dash. Does yours not work? If it doesn't work the problem could be in the cable and not the valve.

Heck, you might need some heat now and again up there. We are headed to Banff soon and it is going to be rainy and cold!!!

I think it is the flaps or the cable/lever. It constantly blows hot air and I'm looking for a quick fix.

I have accessory front heater valves available for a positive shutdown of the front heater in your Vanagon.
This is the quickest forever fix.

Installed one of TK's valves in about five minutes the morning my wife and I were leaving for the Grand Canyon. Without it, a bit of heat still comes through, which is no fun during summer.

I put a 5/8 coupling where the old heater valve was and put the ford valve where you put your TK shutoff valve but in the pressure line. It turns the heat on and off right there by hand. Not bad for 15 bucks and a trip to FLAPS.

Thanks everyone! I have a new heater valve, but I'll just keep it in the bag for now. I don't like the idea of splicing in things and adding more failure points. So, I have just disconnected the cable to the old heater valve and manually shut it off for the summer. What makes the Ford valve better, or is it simply a cost factor? TK, why the screw in couplers? Dave, the pictures are great, I didn't even know where the old valve was until you showed me! Doug, I have a Propex, so we're coved! Wildthings, when I do the teardown on the dash to rebuild, I'll be able to check the cables.

Why the screw in couplers on the valve?
Because Parker doesn't manufacture the valves with the barbed fittings on them.
It would eliminate the choice of the type of fittings at the end of the valve one might want to use.
I don't think I've ever seen a high quality valve with ends on it as a one piece item.
Plastic valves are available this way -- because they are molded .
Short lived valve in comparison.
This is why I went with the Parker assembly.
It's designed to be used in high temps & pressures for longer than the often failing plastic valves.
They don't leak, they don't fail in this application.
It's a one time update.

Another vote for Terry Kay's inline valve. It's very solid and completely shuts off the heat. Pay attention to its location, and you can reach behind the plastic shield and turn it on if you get a sudden cold spell.
We don't need no stinkin' cables! |

| Hmm. Actually, I was kidding about not needing the cables. I've just been too lazy to fix mine properly. |

| Installing the stock heater valve is kind of a PITA but I have had good results with them working properly without needing a secondary shut off valve. |

I forgot to mention this feature of the Parker Valve set up;
Your not limited to where it can be fitted.
I spliced mine into pre T- fitting under the van.
Why?
Not only did I shut the front heater core off, I got the back one too.
So yea, I have to lay along side of the van twice a year-- once in the fall, & once in the spring, but I get it all with a flick of my finger.
One of the better accessories I came up with for my Vanagons-- pretty much eliminates the hot foot syndrome.

The reason I fixed my cable controlled valve PLUS added TK's valve was because of the front air box design and Summer.
In the stock configuration you CANNOT stop the fresh ram air from being forced into the Box (I modified mine so I can but that's another story).
If you cannot stop Air from being forced into the Box plus the flap seals will not/may not seal 100% you end up with warm air if you have any failure of the hot water valve being able to close fully.
Now, the AC unit is in the rear..... The last thing I want on a 90* day with 90% humidity is hot air coming out of the dash while the AC slaves to move cold air to the front. (Also why I made my fresh air able to be shut off)
With both valves, I have duplicity of shut down. One or both will prevent water from entering my heater core!
This is important to me and was worth the price of TK's valve.
Come cooler weather, leave TK's valve on and use the cable controlled valve as designed.

ditto that I replaced my factory installed valve with an original type (Van café item) and it works fine four years later. the original one was working fine when removed, I simply replaced it to avoid any potential problems using a 20+ year old valve when I replaced my radiator, and rubber hoses, also as a preventative measure.
I'd replace the stock valve with a stock valve again, no problems with them.
Why go funky when you can do it like the factory and retain the original controls???

Because IMHO the Ford cable clamp and control wire to lever attachment system is far superior to VW's design.
I have full functionality via the VW cable using the Ford Valve.
Plus IF I need a new valve..... Any parts store in anytown USA should have one on the shelf.

I installed the valve that Terry K recommended a few years ago and honestly it has made my driving experience 1000x more enjoyable.
he used to make a jumper cable setup that was not easy jumping and I went to his websites and they were dead.
Anyone know what ever became of Terry K? I know he was banned but that happened even before I joined the samba I believe
