well found out where my aircon gas went.

when it was on ramp  yesterday and I was looking for coolant leak

the air con rad seem to be falling apart the one behind main radiator

looks like bottom fell out and there's bit crinkly card stuff falling out of it

how hard are they to change as i aint much of a clue on aircon

and will it cost me a arm and a leg or two

[Edd]

quite a bit of work, weld new one in then pressure test then regas

No mate its just bolted in  :-? :-?

[Edd]

[Edd]

If its just the bottom run, thats ok, mines done it a bit,still works fine.

They are quite fragile and damage easily, wrong time of year to tell, but its its working i'd leave be until it/if fails

A/C condenser/radiator is in front of the the main engine radiator.

I think they both have aluminium fins that can corrode (and look like soggy cardboard).

You obviously have done one of these before 

You undo the unions at the end of the pipes mate!

[Edd]

not on the omega hence i wasnt sure about it being unions or not but have on others

acons not working it blows hot air

was when i got car iv done 25k on it its at 82k now
about 7k ago want really chilling but haven needed it

but that defernatly it the condencer thing in frount main rad

and does look like soggy carboard falling out

if it just a bolt in job i may try my self with a used one
cant really weld it my self

so can you just basically just bolt it in and then have it refilled ?

if so ill have a go when it warmer

its not like i need aircon at the moment and the weather we been having

[Edd]

it will need a pressure test to be sure its not got any leaks then regas, im sure someone on here was offering a overhaul for the aircon but cant remember how much

Simon Omega was .. but he's a long, long way from Luton !!

In principle yes.

It is very important to use new sealing rings and keep everything absolutely clean and dry.

I have had a failed condenser then 3 days later the compressor seal failed.

I got an air conditioning engineer to pressure test mine with nitrogen to find the leaks before it was taken apart.

Doesn't need any welding - don't listen to advice from people who haven't done the job!!

Need to remove radiator, see http://www.omegaowners.com/forum/YaBB.pl?num=1265139824

Need to remove residual gas (if any) from a/c system (vac pump - illegal to discharge gas to atmosphere  ) - disconnect air con pipes at unions with a/c rea, unbolt rad and lift out.  To fit reverse of removal.  Refit cooling rad, refill cooling system and bleed.  Leak test a/c and regas.  Not a particularly difficult or long job to do.
