If you do it don't forget to either make a bracket for your power steering pump or easier way is take the aircon pump apart and use the front of it as a bracket

Oh yeah, 100% this. I took mine apart and used it, better safe than sorry and hardly any weight in the bracket

Removing it will make for slightly faster and easier engine removal when it blows up ;) Just removing the A/C pump without thought to how the pump casing also gave support to the PAS pump will probably see you with a broken engine block casting, proceed with care.

Hi Chris and everyone, i will not be removing my aircon pump, there are far more downs than ups, with this current weather it is a no brainer, but unfortunately i am advised that if i have not used the system for a long time, then it my set up will not recover, corrosion, split seals etc, and repair costs are extortionate, not sure how true this is. ? herbiemercman.

I believe it's said that using air con regularly migrates the oil around the system, and lubes "seals and things". How true it is I don't know, I can't recall when I last had a car with air con that actually worked, and despite this temporary mildly warm spell, I can't say not having it bothers me unduly. Now it's commonplace the number of people who can fix it has risen dramatically, but the Greens have had their way and cheap, efficient refrigerant gasses have gone by the wayside, to be replaced by mega expensive, inefficient substitutes. ask a Mercedes owner of the last few years who has had to pay dealer prices for their ludicrous refrigerant.

 

 

Propane works fantasitcally, but is "interesting" if it leaks, either slowly into the interior, or suddenly in a big impact. I am told a LOT of inner city private hire drivers use it... One step beyond red diesel though ;)

Does it blow out cold air when it's switched on? If so, then just use it. :-)

 

If it doesn't blow out cold air then it'll probably be low on refrigerant - either down to just gradual loss over the years (normal), or a leak.

 

Take it somewhere to have it filled back up and they'll tell you if it has a bad leak or not and they should only refill it if the system appears good. A check/refill is about £35 - £60 depending where you go.
