Heater Hoses

Recommended Posts

CC don't do the correct heater hoses for my '97 car.

 

It's the 2 moulded elbows I need. Any clues as to where I can obtain said items 🤔

In any case I replaced mine with OEM hoses. Caterham couldn't supply so I tracked down the manufacturer (Clayton Heaters Ltd., Coventry) and got them from there for £8 inc. post. Their number is/was 02476-691916

I've just spoken to Clayton heater's, It seems they have the CX4609 in stock *thumbup*, but not the CX4608 *thumbdown*. I ordered 2 of the CX4609's as it sounds like this is the longer one and may be able to modify it to fit.

BTW they're £8.50 each + £7.80 carriage + VAT ☹️

I had all this pain last year, caterham, Clayton etc. I finally went to Think Automotive in Isleworth Mx. The problem on my car is that the heater hoses taper from, Ithink, 16mm down to 13mm.

 

I bought silicon hoses of the correct diameter and a metal reducer to join them. It wasn't the cheapest option, but it may be the only one, and being silicone they should last longer.

 

They are on 0208 568 1172 and you can find tehm on the web. I found them very helpul in trying to find a fix - they were not just selling off the shelf parts

I cant see that the heater hoses on my car reduce down from 16mm as suggested above as I've measured the pipe spigots on the heater and the watervalve and they are all the same diameter.

 

Of the two hoses supplied by CC only the outlet hose (longer of the two) will suit (I think) as the other has an offset that isn't required.

 

Another complication is that I'd like to fit a fill / bleed connection to the heater inlet and to that end I've bought one of 'Grimreaper's' magic kits. Has anyone any experience of fitting / using these?

 

I suppose this could alternatively be fitted in the bypass hose if I were to disconnect the heater and do without for the time being whilst I sort this out. I'd lengthen the bypass hose to a point where I coul raise the bleed connection above the expansion bottle. Any thoughts on this 🤔 🤔

Good news 😬

I fitted the hoses from Clayton tonight, and the CX4609 hose can be cut down to make a CX4608 *thumbup*

The hoses on mine definitely taper, the connection to the heater is smaller than the connection to the valve.

The tee piece should go in the top heater hose (the one that connects to the top rail) as close to the heater control valve as possible to make it the highest point in the system, top the system up from this point with the expansion tank cap ON otherwise anything you put in the tee comes out the tank top.

Ged,

 

I'm P*ssed off that you managed to source the hoses from Claytons. Last year they told me they were obsolete and didn't make them anymore. I spent weeks trying to source something *mad*

 

Can you let me know what the bore size and approximate dimensions of the CX4609 are please? I may buy some for future use while they are still available.

 

Thanks

Ithink the girl at Clayton's said they had 82 of the CX4609's in stock.

 

These sizes are the best I can measure off the old hoses

Dimensions are overall, not centreline of elbow.

 

CX4609

Short leg to heater - 65mm

long leg to valve - 180mm

 

CX4608

leg to heater - 58mm

leg to valve - 58mm

 

I.D. for both

Valve connection - 16mm

Heater connection - 12.5 mm
