CAn anyone tell what that water hose on the header side of the engine is? Looks like it goes from the water pump to the firewall, its metal.

Thanks in advance

well if it goes from the firewall to the bottom of the radiator it is connecting to the heater core through the fire wall

 

Yep, heater return pipe.

 

The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.

 

So far I have found this manual to be almost totally useless for my 91NA.
Pictures (when there are any) are from an early 2nd gen, as are most of the descriptions for removal (see "removing outer doorhandles" for an example of how significant these little differences can be).

Furthermore, anything below gross assembly level is frequently ignored altogether, glossed over (the reason I wanted to remove my doorhandles was to remove the lock cylinders-the Haynes description (I paraphrase), "Remove and replace the lock cylinders"...brilliant!, why didn't I think of that?) or labeled as beyond the scope of the manual/capabilities of the home mechanic, "See your Mazda dealer for service".

Admittedly the sections on Engine, Transmission seem much more detailed but I haven't needed to look in there much (yet).
To me, the value of a model-specific manual is in it's coverage of the myriad details unique to that car and not the generic stuff ( for some reason, Haynes has no problem detailing a brake caliper rebuild but deems cruise control install/adjustment as too risky/sensitive for any but the professional).

Lock handles replace them selves with the power of magic apex seal dust, didn't you already know that, noob.

 

It sounds like that's because so far you've only tried to use it for things it was never intended to help with.

There are far, far more similarities than differences.

Install? Why would a repair manual have instructions for installing equipment that wasn't originally fitted to the car? The cover says "Diagnosis and Repair", not upgrade. You won't find that info in the FSM either for the same reason. And there's nothing on the cruise control to adjust.

Your criticism of the Haynes manual is completely unjustified because it's based on your own misunderstanding of what it was intended to be used for. It's an excellent resource for most people most of the time.

 

The haynes manual does not show it, I have one. Thanks though.

 

Thanks where can I get one I think the metal is wearing, I see alittle smoke/steam coming from the elbow in it.

 

Praytell then, what exactly is a service manual for if not to explain how to remove/replace/adjust components and to detail what (if any) differences there may be between model years?
Cruise control was installed originally on the car but that's neither here nor there...my point was that the manual is full of generic info (there is nothing special or distinctive about FC brake calipers) while glossing over the details that are model/year specific.

No I didn't.
The Haynes neglected that little nugget, too.

 

Page 103 and page 107.

FSM has it as well.

 

Sorry dont have one, anyone know where I can get a new hose(metal part) other then the dealership?

 

Junkyard?

 

Odd. The metal could only wear through if it were rubbing on something, but that pipe is fixed and doesn't move. Take it out, clean it and look for a hole. If you find one take it to someone wwho can braze it up. That'll probably be cheaper and easier than replacing it.

In my experience (and it sounds like I've used it a lot more than you have) it does that just fine for most things on the car. It's totally unreasonable to expect a manual like this to cover every detail to the nth degree. If you want that go spend $1000+ on the FSM for each model year.

You said you were looking for info on "cruise control install/adjustment", implying your car didn't have it. I would not except to find info on installing cruise control in a car that didn't originally have it in any service manual, because that's not what they're for. And like I said, there's nothing to adjust.

 

Actually, I said no such thing.
I was marvelling at the oddball nannyism that leads them to say-
and yet allows them to detail the complete strip down of a brake caliper.
Apparently, screwing up your brakes is less dangerous than somehow misdiagnosing a cruise control issue.
Furthermore, the only checking of the cruise actuator they deem fit to mention involves the vacuum line...which the S5 doesn't even have (but you of course knew that).
That shouldn't be necessary.
The Bentley series of manuals (primarily aimed at British sportscars with a smattering of other makes thrown in) covers in exquisite detail almost every nut and bolt on a vehicle and takes care to mention if one model year differs from the next, a phenomonon that completely escapes Haynes. They are available for under $75...a bit more reasonable than your $1000 suggestion.
Sadly, they have no offering for the RX7, so the Haynes will have to suffice for the nonce.

 

Like I already said, the Haynes manual is fine for most people most of the time. There will always be exceptions like you, but most people who use the Haynes understand it's target market and use it in conjuction with the FSM to get the info they need. If it's so bad, stop using it. It'll be your loss not ours.

Now quit whining, nobody cares...

 

right............... thanks, I will pull it and check out the hose.
