heater slider

[pimms]

Could someone tell me the measurements of the heater slider surround of the original Strato's ( length, width, hight ) so i can make one . Or is there a source for buying them? I believe its a part used on several Ferrari's?

Thanks!

Grumpy Bates does a housing moulding for it.

Here's a GBates slider mount. (slider knob isn't the correct one)

[pimms]

Thank you guys , but what i need is the Chrome or aluminium part , not the dash part!

Chris, You mentioned Europarts (http://www.stratossupersite.com/forum/showthread.php?t=2522&highlight=heater) in this thread, less housing! I sent an email to Graham some weeks ago but have had no response as yet. Is there any other way to contact him? This thread (http://www.stratossupersite.com/forum/showthread.php?t=2248&highlight=heater) covers Graham's offering.

Yes Allen,

I've just looked at Eurospares, they've got the choke one on there for £40:

I think Graham B. must have got a job lot of new sliders once from somewhere? The one on Terry B's car had no knob on it even though it was new and unused, never fitted to a Ferrari, that is.

Hi Chris,

Just looked at the site but can't find out how payment works with these guys?

[strat6v]

I think grumpy made them. Bought one at abingdon last year , moulding, slider, surround and knob.

It's best to phone because their stock of used parts changes from day to day.

Yes Allen,

Yes, I know and it irritates me no end. No much hope of finding just the knob for sale I reckon.

It's your lucky day Peter!!

Superformance are selling them on their own and new for £2.70 +vat.

I got sick of jabbing my head on the 'knobless slider' whenever I had to work under the dash, so I stuck a Metro one on there, sorry!

Thanks Chris - I'm onto it!

All,

Have fitted the Ferrari heater matrix and have read plenty of threads about the slider mechanism (which I'll come back to), but cannot find any threads on the what is the best plumbing approach?

Can you just take off from the main water pipes for both feed and return, or is it best to run a third pipe down the spine to replicate the Alfa approach?

Assume heater valve just sits in line with water feed, but think you must need to fit something in the return to stop the residual water in the matrix heating anyhow, giving permanent heat. Am I missing the point that the valves are designed to shut off both feed and return ?

In which case what is the best heater valve to use?

Lastly the slider mechanism I have seen in the gallery is from what car?

Apologies for what seems like a very basic question, but just gone blank on how this might go together.

Regards

Iain



As per the Alfa manual

Hi Iain,
Thanks for the cheque, will post tom. This (http://www.stratossupersite.com/forum/showthread.php?t=3230&page=2&pp=15&highlight=heater+valve) is a good thread. You need to run a third pipe as per the Alfa set up and use the common return. The control valve sits on the 3rd pipe I believe. The additional return value in the thread was Chris Smith's idea, one which I'm using. I believe Graham Bates has the sliders.

[igosling]

Allen,

Thanks for the feedback. I have a third pipe in place, so I am OK there. But still having trouble visualising what I need to achieve.

Also still confused that if I stop the in-flow, will the heater cool down that much, as there has to be an equal(ish) water temperature in the system. That is why I assumed both pipes need to have valves to stop any flow into the matrix.

But appreciate there are people out there with much more experience than me, so happy to go with the concensus. So... does anyone have a diagram of what this system looks like?

Iain

[strat6v]

If you cut off the flow of water in the matrix then what is in the pipe will stay there and cool down? Probably a bit like your hot water tap at home, unless you have a super posh recirculating system. Try turning on the tap, coolish water for a few seconds till the hot arrives? All it is is a dead circuit that is still pressurised. I think an oil cooler stat works in a similar manner, cuts off flow from one side but still kind of open on the other. The fluid will then move where there is the least amount of resistance, but still under pressure.

But don't quote me on it :)

[igosling]

John,

Was just about to send a thread saying I have suddenly twigged !! Have done enough central heating work to know that my question was flawed.

Any view on what in-line valve to use?

regards

Iain

Andreas used a MK2 Golf I believe. I would also consider adding Ford Kaa recirculation valve, which will allow the third pipe to flow back through this into the main system. This I believe help keep the head cool as this is where the 3rd pipe originates.

Chris

Thanks for the link to Holden. Will fit the bill nicely.

Can I just clarify that the ideal system therefore comprises of:

1. A take off of either the top or bottom hose to the heater matrix (valve in line with this connection)
2. Return from the heater matrix to a third pipe that returns to the connection at the top of the block (Alfa engine)

or

Is it an option to send the return from the heater matrix back into the top or bottom hose?

Thanks

John


Take the flow from the rear of the block and pipe it to the heater via a control valve, the return from the heater is then tee-d into the lower return pipe from the radiator

Ken,

Thanks.
