Hi chaps - once more the hot weather has prompted me to get off my butt and fix my air con...

Right. The condenser has the usual problem for a MK2 and is 50% rust and holes. I'm going to replace this but is there anything else that will need doing whilst I'm there - I heard that the drier might need replacing too?

Also I need to replace a bit of rubber hose that has become worn as the re-gas guy said it would pop once the system was recharged. Any ideas where I can get some replacement hose that would be suitable for the pressure?

Near me a leak check is £32 and the re-gas £60. Sound right?

Lots tend to go at the bottom - remove the cover at the front and you'll be able to see the rusty slush that used to be your condenser... Only way to properly check though would be a professional leak check I guess.

They shouldn't charge any thing for a presurised leak check. All i had done was had the system filled to 150psi of air. Then it was left for 30 mins and recheckd to see if it had maintained the 150psi of pressure.

This was done for nothing. Ithen had it re gasssed and uv dye added todetect for any leaks. I was chrged £45 for the regas and £3.99 for the uv dye to be added.

I personnaly wouldnt be paying £32 just for the leak test.

Anyone discharged aircon themselves? Looks like it could be a dangerous diy job?

Got an immobile Mk2, the last Verona, but was fitted with a new "revised" aircon condenser when coming up to three years old. Still got pressure in the air con, tried the low pressure valve squirt trick. Would like to get this condenser off to use on another Mk2 ... but can't take it anywhere to get it discharged.

Haynes manual also suggest a special Ford tool is needed to remove the condenser pipes?

Anyone done this themselves? Was hoping to find some way of swapping it over and then get it recharged cheaply at Kwik Fit or where ever ...

condensors are pretty cheap on ebay,unless you know that the condensor is fairly new i would not use a second hand one,you might go to the trouble of fitting then regassing to find that 6 monthes down the line its said mate get a new one unless your sure the other is as new.

An AirCon system should never be filled with compressed air. If it was filled with air then no matter what was done after 30 mins, the accumulator will be destroyed or will not last very long afterwards.

Air contains moisture and an accumulator absorbs moisture and the process is not reversible. After 30 mins of compessed air the accumulator would be on its way to being saturated.

The only reliable and safe pressure test is using OFN ( Oxygen free nitrogen ). This is pumped in higher than working pressure so should show up leaks but does not always do so. A full leak test would then be by holding the system at a vacuum and see if it stays. Not sure what would be a reasonable price for a leak test but certainly a proper one could never be done for free by any professional. OFN costs money as does the equipment to pump it in and complete a vacuum test.
