I do have another but I wouldn't trust it? I have a guy who believes he has two NOS but he can't check until Sunday? Spoke to Ivan and he knows the SP anyway...........

Hi Magic,

Most good radiator repair places here (particularly those that do trucks) are able to pressure test AC condensers and evaporators, and repair them too. I would ring some places nearby and see if they can do the same there? At least that way you will know if the spare you have is okay if you need it, not to mention getting others repaired if necessary.

Where it starts to become a problem is when the fins start to get fragile, as they are getting on Bast. She had a secondhand condenser fitted as part of the efforts by previous folk to fix the slow AC leak (which is the evaporator), and the fins are very brittle and fragile. Even with much care they will eventually crumble and the condenser will lose its effectiveness - time for a new one.

This is going to become a problem for people who are caring for V12s. When I have nothing better to do I will buy the closest matching six cylinder condenser and see what it would take to modify it for the V12 pipe orientation and fittings. There are very good aluminium solders available now and as along as any joints are soldered slip joints they will be more than strong enough.

If your contact has those NOS condensers, I would be inclined to grab one yourself and put it away for that rainy day!

Best,

Starbuck

All good advice for sure Myzon! As I mentioned elsewhere on here, Sercks services are the biggest supplier/repairer/reconditioner of radiators/condensers in the UK but they refuse to repair condensers? I understand that the pressure in these things is around 5 bar which I find quite astonishing so in a way, I understand some folks reluctance to guarantee or carry out any repair? I have a spare condenser that I bought at the Coventry auto jumble two years ago but I wouldn't sell it as I don't really know it's history? I am going to have it pressure tested on Monday though and if it holds up to scrutiny it will be boxed up, racked and labelled for that rainy day!

Yes, Hella made the condensers.

Repairing one (if you can identify the hole) can be done with epoxies. My own was holed and I used a product used in the HVAC industry to effect temporary repairs, followed by a stronger reinforcement. That was 2 years ago and my A/c still blows nice and cold.

The products are "LA-CO heat-seal stik" and "JB weld". Ebay will probably have them.

The Laco stick looks like green sealing wax. You heat the holed area and melt/puddle this stuff on. It hardens in less than a minute and gives a gas-tight high pressure seal. It really works well and will seal a holed condenser.

Laco is very brittle though so you need to reinforce the repair.

Lighly sand/wire brush the Laco and then build up a sleeve of slow-curing jbweld over the laco. I didn't use any material like glass fibre or kevlar in the mix, but you could do that too. Give the repair 24 hours before reinstalling the condenser in the car.

Oh and btw, identifying the hole is done with a strong UV lamp in total darkness and the 24 LED types sold on ebay are perfect for the job.

This can be a good way to get yourself up and running again when the last of the replacement condensers has been sold. 8-)

cheers
