RSD_63...Reply to your question

Post by MGVWfan »

Howdy! I figured I'd reply in a new note to get the thread out of the "who am I?" thread. Here are your questions...
Just got a 1974 412. A/C - F/I - Auto. The body is in great shape, only surface rust. The motor was out but I have it and most all parts for it.
Questions and concerns:

1. If I remove body rubber [glass, fender, doors..] can I get new ones to put it back together with.
ReVolks in Siloam Springs, AR had the seals when I pulsed in December (I've still gotta call them and order mine :oops: ), do a search on this forum and you'll find the thread.
2. As noted above, motor is F/I. Friends tell me to scrap that and go carbs. Any recommendations?
Keep the FI if you can. Yours should have Bosch L-Jetronic, which is a simple system using an airflow meter. If all the pieces are there, and the are in decent shape, either L-Jet or D-Jet (the system used on pre-74 411's/412's) are far better at metering fuel for the T4 engine. Before you decide, take a look at this link for further info...

Note that the Porsche 914 had the same engine as the T4, so the same considerations for carb conversions apply to us.
3. Anyone know the source of an on line owners manual? I need to figure out how to put the battery in.
There are online wiring diagrams, but I don't know myself of a place with a scan of the owners manual. However, the battery goes under the driver's seat (you probably knew that), and getting the seat released so it can tilt aft far enough to remove/replace the battery is usually the problem. There's a little lever under the left side forward of the drivers seat, and if the linkage isn't too distorted (mine was), you can pull the lever to the left and cause the seat vertical travel locking pin to disengage from the "Y" shaped steel support under the front center of the seat, and tilt it rearward. If you can't get the linkage to disengage, try spraying the pin up under the seat with S'OK, WD-40, something to loosen it, then try it again. If that doesn't get it, you'll have to wedge yourself under there with a pair of mole grips on the silver 90 degree pin, and pull it out of engagement with the vertical adjuster rack thingy. After you do that, remove the seat by pulling the seat fore-and-aft adjuster up to disengage it, and sort of rock the seat forward in its tracks until one side is disengaged. Then you can get to the linkage that's distorted, and pull it out and shorten it so the little lever can disengage the pin again. Lube up the vertical travel adjuster's pin, reinstall the seat, and you'll be able to get to the battery as Wolfsburg intended.

Hope that helps! Welcome to the fraternity of T4 owners! :D

Comment allez vous aujourd'hui Albert? :D

Interesting! Every one I've seen has the main battery on the left (driver's) side, the auxiliary when fitted (offloads the main battery for the Eberspacher and any other extra loads) under the passenger's seat. Note that driver's and passenger's references are in the non-UK (LHD) sense, with driver on the left when sitting in the car. Maybe yours has the primary and auxiliary batteries reversed?

On the externally-vented battery, yep, I did that, too! The battery is a Group 47, used in some models of BMW and Audi, and Auto Zone has it (among others). Mine came with a rubber elbow and vent tube, and I added a short length of stainless steel tubing to take it through a hole I drilled near the rear of the battery. This contraption makes sure the gases vent under the car away from the engine and Eberspaecher. It keeps the fumes out of the passenger compartment, and should help with corrosion in the floorpans, too.

I'm not sure I'd hook the vent line into the fuel vapor canister, though...

Clarification...the hole was drilled in the FLOORPAN, not the battery :D

I was thinking of using one of those Optima batteries, seems like this would be a perfect use for them, eliminating the need for venting, etc...

When I went looking for a battery and found this one, and then I priced an Optima, I think my billfold made the decision for me :oops:

No doubt, the Optima sealed technology is sure an elegant solution.

One thing's for sure, I personally don't want to put an unvented or unsealed bettery under my butt :shock: I'm surprised VW continued that T1 convention (unvented battery) into the T4 era.

Optiomas are now available at Pep-boys and autozone chains. They are about $139-175 USD. Get the yellolw top marine deep cycle ones if you can afford them.
The really cool thing on the 411/412.....but useless now that you cannot get the original battery...is that mysterious yellow and red wire that is under your seat. It went to a hydrometer/float cylinder in the top of the factory battery. It led to the test harness. They could check battery condition from the plug in the engine compartment....cool!
Albert...was your car originally shipped into Canada? Its possible it was fitted for right hand drive . If it has a manual transmission and is 4 door or variant, it would definately have been what we consider a "gray market" car....and could have an manner of differences. Ray

Albert...you are the only other person I have met that has noticed the hard point for the back seat, 3 point belt. They are actually in all 2 and 4 door sedans. Or...I have sepculated that that hard point can also be used for a vent window latch for "pop-out" quarter windows like on type 3...but I am unaware if they ever offered that on the 411/412. I will be installing the extra battery option on my car as well. It will be useful once I get the AC back on the car. Ray
