I was looking through the 86-81 RX7 Haynes Repair Manual and saw that on page 54, spark plug replacement section, it says, I quote "leading plugs go into the upper spark plug holes and trailing plugs go in the lower holes". Well most of know that's wrong but this is a heads up for some of the noobs so hopefully they don't get it wrong following the Haynes manual. Here is a pic of the wrong info in the Haynes manual and the last pic is from the FSM page G-27.


And the pic from the FSM

I'd rather use the Factory Service Manual anyway... At least it's not Chilton's trying to group 5 unlike vehicles into one book.

I agree 100%, this is just a FYI.

I'm glad you put this up. For one it helps show that manuals can be wrong, and it's just plain helpful to anyone in certain circumstances. I've heard that the FC Haynes is also wrong on a few wiring points.

The last picture is from the FSM.

No, that last pic is from the FSM not the Haynes.

Edit: SpeedOfLife types faster

Haha why is it I have the 86-91 Haynes manual too... but i'm missing a chunk from like pages 32 to like... 60? And it's not like it was ripped out or anything, it was just never printed and bound. I'm missing the entire spark plug section :P

Funny in 12 years of FC ownership, I never noticed that error in the Haynes.

The Haynes folks must've caught the error at some point because in the newer edition (the version with the color photo of a red 4-lug base model on a green background on the cover), they correctly have lower = leading; upper = trailing. I also have two copies of the earlier printing like the one shown in the photos by the OP and they are both wrong.

I guess the moral of the story is it is best to rely on the FSM.

The Haynes manual I have is right...






It's kinda hard to read (camera phone) but it says Leading is lower and Trailing is upper.

As daviddeep said they must have learned of the error and fixed it before the revised edition could come out.

Even in the earlier editions, the text explanation of leading and trailing that appears on page 55 is actually correct which means it conflicts with the caption on page 54.

Since lots of the early versions of the Haynes manuals are obviously still floating around, it's good that George84 pointed this out.

Small correction to a previous poster regarding the car on the new Haynes cover. It shows a GX, not a base.

Going on 12 years of FC ownership and never noticed the error either. So I guess it's just the text below the picture in the Haynes manual that is wrong on the earlier versions?

I mainly use the FSM, but the Haynes is excellent in some areas (brake pad replacement, maintenance section, lots of pictures).

When I first got my 7 it came with one of those manuals. The first thing I did was change the plugs.

I had to get on the forum to double check where they go because the manual states 2 different things.

Because of that it took 45 min to change spark plugs. And we have some of the easiest plugs to get at and change.

As if someone who just got their first RX7 isn't confused enough.

well i looked at the T and L on my housings... because my factory service manual is pink.

ivegonemad

This is also a lesson that you should just pay attention to your car, especially whenever in doubt. Our motors have T and L right next to the plug holes.

look at the side of the hanes manual, who is the maker of the Rx7 cause it isn't "MAZDA"

Hey pfsantos, out of curiosity, how can you tell the car on the cover of the Haynes manual is a GX? That is a Canadian-spec model, right? You can assume it is not a U.S.-spec '88 SE because it doesn't have any decals. But couldn't it also be an '86-87 U.S. base model?

If I remember right, the sticky mentions this would be equivalent to the U.S. spec. luxury edition, since it has the 4-bolt aluminum wheels. The base would have steel wheels. That's all I can tell since the picture only shows the outisde.

And yes, the GX is a Canadian trim level.
