Need help tracking down heater parts - where is the best place to go

Recommended Posts

Hey all

 

In a bit of an unfortunate position in that I have a coolant leak SOMEWHERE in the cabin but there is green buildup on everything and I'd rather just replace as much stuff as I can to be sure I fix it (and also future-proof it to the fullest extent possible).

 

Someone on here had a similar problem a couple years ago and was referred to allzparts in Sydney, whom I have flicked an email to (hard to get on phone - will keep trying).

 

I've also tried the zstore in US, and some new site called "datsunzcarparts".

 

Is there anyone else I should be trying?  I am thinking I might try datsport - I know they specialise in 510/bluebird but knowing nissan I doubt they made a heater tap for the 260 that wasn't in 20 other models as well.

 

Any advice appreciated - gotta get the heater workign again asap (it's Canberra, it's May... you know).

That heater on/off valve seems to be a common point for leakage.

I was chasing one from all z last year but were waiting for them to come in.

In the mean time I found a non leaking one in my spares.

Hoses can be a bit of a pain to source also.

It would be nice if someone could supply and under dash hose "kit" to change all out at once.

Do you have the later model with vacuum control of switching or the earlier cable type?

I agree, the heater c0ck is the most likely spot for the leak. Drivers side of the trans tunnel up near the firewall. I replaced the two moulded heater hoses that attach to it a the same time.

 

I can't really see that many places that you can have a leak, Its either those stated above, or the core itself.

 

Hoses I got from Allzparts. Water shut valve, I found a nice looking one from a wreck I think?

if it helps at all.....as a temporary fix you can buy the universal switch sold at places like Bursons.

When I looked 4 years ago, I could not find an original one anywhere.

 

I still have heater problems, but the leak is gone.

(the switch is a bugger to mount unless you are feeling inventive, i have left mine hanging which means the switch does not operate as well as it should (yes, lazy i know).

thanks guys, it does have a cable from the actual tap device to the heater control, so I guess that means cable driven.

 

I really would like to keep things as standard as possible before modifying etc.

 

With teh hoses, I had a look at some heater hoses at supercheap and it seems like I'd be able to adapt something to work if that was required.  And the core I suppose could be rebuilt somehow, it's really the tap that's the issue.

 

I really don't want to bother with second hand, as it's likely to be little better than what I have on there (ie by definition could be 35 years old anyway). 

 

I read somewhere that people speak of dismantling the bloody thing and changing the diaphragm?    But then hell knows where I'd get the parts.

I've seen new taps advertised on US websites but think they were only for 240 and from memory were different to the 260 otherwise guess I would have bought one at the time.

Evilbay has a new heater tap for $32 U.S. suits early cable drive  ;)

 

which search term did you use?  I used "260z, heater" (which, incidentally, brought up the heater cores, which I will buy!) but can't find the taps.

 

Link?

There should be a similar curvature (one that bends 180 deg) hose at SC, you just need to shorten it to fit. Having it in boiling water before fitting really help too, I'm sure you're going to have alot of fun doing it  ;D

I replaced mine when I rebuilt the car. I got it new from Black Dragon. However I heard somewhere that you can replace the tap with one from a falcon. I don't think it was quite that simple, from memory the Falcon unit usually sits in the engine bay. I don't have any more detail sorry.

hey, i have the heater system out of my 260 coupe. its just sitting in a pile in the corner of the shed.

I could be persuaded to part with it for a bit of coin.

Im also planning on doing an order from MSA for a rubber kit very soon.

We could combine orders to save on freight.

Im located in canberra too, so yes, i agree you NEED a working heater.

(my DD has a barely functioning heater, makes for a fun drive)

 

Pm me if your interested.

Thanks, I've been trying to get in touch with MSA but so far no response.  Normally they get back in a couple days, so will wait a little longer.

 

Chris, don't think I'll be able to make Saturday.  Driving around with a passenger floor full of heater components and a boot full of dash console is not heaps of fun.

 

Nizm0zed, thanks for the offer, but really I would probably have to kill myself if I replaced the tap and it leaked again.  Is there any way of checking if the tap is in good condition?

I've never had a problem getting Warren from allzeds on the phone and MSA..

Your not trying hard enough.

 

Any auto shops sell Universal heater taps.. I worked at Autopro and we sold them.

Try looking at Benzeds build thread, he used electric heaters. No heater core, no silly tap, no leaks and best of all you dont need to wait for the car to warm up before you have any decent heat/demist.

Well, I have got a new heater core and the rubber preformed hoses at home, but still no luck with the heater tap.  The nissan dealer has access to all the parts except this one.

 

Here's some pics of it - anyone got a decent second hand one they may want to sell?  I might take this one apart to see if there's some way of repairing it so it doesn't leak.

Yep I just went on ebay.com (ie the US one) and entered 260z heater core and a bunch of hits came up.  This one was $99 USD, but postage was another $45 USD or so, in the end it worked out to around $170 AUD.  There were ones on ebay.com for around $79 but they wanted heaps for postage, it was cheaper to get the $99 one.

 

Also there is some guy in Washington that reckons he can refurbish the later model 260z heater valve, so I am seeing if he can help me out.  Seems like they're not selling new ones anymore.  Will post up if it works out.

Dori, the rubber seal between the diaphragm and pipe is rotten hence the leak, it leaks at the triangle plate and the breather hole of the diaphragm. I couldn't find a replacement seal so I used metal bonding compound and sealed the triangle off, for the breather hole I used a tube and direct the leak back to the coolant reservoir. Not exactly a fix but at least it doesnt leak anymore.

 

Another method is to buy one of those 280zx's control valve on the bay and use it as the substitute, I think if the pipe diameters are the same then we can just swap the diaphragm and seal over.
