RRC 1988 with fully working aircon - brilliant you may think. Well yes, in one way, but the squelchy carpet says otherwise.

exit tube is clear and in case anyone worries there is no water under the vehicle it exits onto the exhaust...

however there are two water drains off the a/c as far as i can see and i had a pipe that was 'unconnected'. Seems that LR in their wisdom specc'd plastic outlets for the drains and over the last 30 years or so that has got brittle and broken meaning the water exiting into the footwell and rotting the floor.

Either way if this happens to anyone the interior diameter of the pipe is 9mm. You can get 10mm ally tube in meter lengths of which you need about 4cm. File it down all around, dab of instant gasket and sleeve it. I'm happy to sell my remaining 96cm of tube if anyone wants it!

Seems to be working.

Oh and get your R12 changed for R24. These guys sorted it for me http://www.subzeroac.co.uk/classic-cars/

Good to read you sorted the problem.

I don't have AC in my '87 RRC but am slightly confused by the term R24. My '98 BMW has R134A refrigerant, so has R24 superseded that product in modern cars?

For pre-93 (I think) everything ran on R12 which was wonderful apart from being pretty bad for the environment. They moved to R134 which doesn't work in R12 equipment (well it does for a while and then ruins it - different oils etc). Most people seem to have either abandoned R12 and do without or done a full upgrade to R134 which is expensive. I'm tight and i don't like sweating - also an engineer who refuses to believe there isn't a solution - so did a lot of digging and found R24 options. R134 is the main thing (now superseded again by 1234), but for niche applications like the RR and Rollers etc with R12 equipment it's the alternative. Been on the go for two years now and no worries.
