Eng Deck Lid Vents

Post by super beetle » Wed May 21, 2014 7:14 am

Does anybody know the proper Engine deck lid for a 1971 Super Beetle Coupe and Vert. The coupe (born Aug 1970, one of the first Supers ever) came with 2 rows of 5 vents (total 10 vents). The vert came with 4 rows of 7 vents (total 28 vents) installed and a spare with 2 inner rows of 6 vents and 2 outer rows of 7 vents (total 26 vents). All are in great condition.

IMO, 7-7-7-7 would be correct for the 'vert (both it and the 6-6-6-6 are rare), and 5-5 for the Sedan (same as `70 Sedan & `68-`70 'vert)...but the 7-6-6-7 would be used later - by `72, both 'vert & Sedan used 7-6-6-7.

1970 sales brochure. The Convertible is Standard-based (last year) and you can see the 1970-only bumper-bracket reflectors. The 6-6-6-6 configuration "officially" debuted for the 1971 model year, but VW often used up old stock before incorporating a change, or as in this case introduced a change somewhat earlier than officially documented. What I find confusing in this picture is that the 'vert has the "1971" engine lid, yet both cars have the two-tone 1969 rims.
Sales brochures are typically prepared well in advance of model release, which explains the rims...but where did the 6-6-6-6 lid come from, assuming the picture was taken a year before they were introduced? Evidently it was determined early on that the 1970 1600SP convertible didn't really need more cooling than the `68/`69 1500SP did and the 6-6-6-6 lid was shelved until the introduction of the 1600DP. Some swear that 6-6-6-6 was used on `71 Sedans and 7-7-7-7 on `71 'verts, and that they compromised for `72 on the 7-6-6-7 arrangement for both models - but because VW apparently used whatever was in the pile sometimes, there seems to always be an exception to any "rule".

7-7-7-7:

Then there's the 7-6-6-7 with thermostatically-controlled auxiliary flap, first seen (I believe) on 1974 California-emissions cars and later on most US-market cars; not found on Canadian-market latemodels, apparently it wasn't considered to be warm enough there to justify it:

And there are Brazilian-made replacement lids which have a wider gap between the two center louver panes where a VW emblem resided on the Fusca; several variations in louver count on those, as well.

Thanks
I thought that the sedan was correct with the 2 rows of 5 as left over from the standard line. The Vert I was not sure, I don't know why the PO got the extra lid as the original is in great shape. (as is the extra) but then again. He gave me a brand new top with padding and headliner, but the top frame still needs a lot of work. he also bought rear seat covers but had no rear seat. Bottom line. I don't know why he bought all the interior and top parts when the rest of the car needed more important parts before time to install interior and top. Oh well his loss my gain.

IMO the 5-5 lid is "borderline" for a 1600DP (in a warm climate, anyway) - perhaps he intended to replace it with the 7-6-6-7.
Or sell the rare 7-7-7-7 to someone who'll pay handsomely for it and run the 7-6-6-7 on the 'vert - most folks wouldn't know or care about the difference.

I think its very interesting. One of those quirky trivia things that'll strike up a good convo in the shop. I had no idea there was a "rare" late deck lid..

Here's one of those Brazilian lids with the gap in the middle. The rows go 8-6-6-8. I think the outer rows of eight look kinda cool. I have one of these rusting out at the bottom that I'm going to use the outer rows only, grafted into a 67 lid... mainly for dual carb air feed on a big motor, and something a little different.

I have a 1967 bug. Because of overheating I added vents. A neighbor had a convertible that he wanted to convert into a Baja buggy so he gave me his engine lid. I cut the block of vents out and welded them onto the '67 engine lid. I don't remember what year the convertible was.

I was trying to decipher the rear deck lid vent situation on the later bugs and supers.

I have a 71 vert (June 71) that came with 7,7,7,7 deck lid. I've only seen the 6,6,6,6 deck lid in that one brochure pic from VW which I believe was printed early MY70 (August 69 or so). So, unlike what is posted above, I thought that the 6,6,6,6 deck lid was a prototype that never really went into production when it was decided that the 1600sp would benefit from the additional row of vents.

I am still puzzled by why VW decreased the number of vents from 28 to 26 staring in 72 only to add additional venting under the light later on.

Any thoughts on this?

Perhaps it was just for aesthetics - the "VOLKSWAGEN" trim is a cramped fit on the 7-7-7-7 lid.

I'd agree that could be the reason. I never added the VW script to mine because I couldn't decide where it should mount. I still have it, if anyone wants to buy it. Regrettably while needing money I sold my '67 that I spent more than 10 years restoring. Got $4k for it. I don't lurk here anymore; it's too painful. ;-)

The position of the script has been moved around. It's hard for me to imagine that it would have been less expensive for vw to eliminate 2 slots in the dies than to move the script holes down.

I have wondered whether vw needed more clearance between the lid and the air cleaner. The bottom center slots are trimmed internally on the 7777 deck lids for clearance but it is still quite tight.

I'm sorry to bring this up but I'm still confused about the number of lid vents. I read different things. I have a 70 convertible that was build on 8/69. It has 7777. From what I understand is that the early 70 convertibles had 7777 before they later went to 7667 to make more room for the Volkswagen logo. I also read that later that year (1970) they added the taillight reflector to the 70's model. If that's the case, why do I see pictures of 70's convertibles with 7777 and the tail light reflector?
Here's another thing...the holes for the license plate bracket on my lid are in a totally different location. They sit really low and holes don't line up the the universal bracket. They are wider apart.
