Thread: Regas with Hychill -30

So, to get it right, I need to replace the drier and vac the system out BEFORE using Hychill 30. I cant just top up 234 with hychill, is this right.

Thats right but why are you doing it?. You have to fix whatever problem you have first.

Not quite on the money

R134a is to be phased out by 2017 in Europe for vehicle A/C,although some countries in Europe are different.

It appears using it in, for example, commercial refrigeration will/can continue.

Australia does not look like banning or phasing out R134a anytime soon.

This may be of interest.

That list may not be hugely accurate for the earlier stuff. A lot of dealers fitted A/C in the 70's. Especially with the likes of cars from France/UK where they don't need A/C. Eg: I just add 300grams to my old Citroen (that has front and rear evaporator units), then top up until the low side pressure looks about right.

The A/C was crap when the car was new, so you wouldn't use R134a unless you had absolutely no other choice. A lot of the A/C systems I've seen fitted to Range Rover Classics on this forum appear to be aftermarket/dealer fitted too.

What are the implications of the system being contaminated?

What sort of car is it .... I couldn't see myself ever having $1000 to put into A/C either. I'd take a punt and buy a compressor from a wrecker. If it's not off the same type of car, I'd just find something like a Sanden SD7 that looks to have the right pulley configuration and see if I can mount it up.

Given it's a 2nd hand compressor I wouldn't pay much for it (it might be no good), but if the AC system you pull it from still has gas in it, you could have a win. Don't buy one from an A/C system that's been "opened" and doesn't still contain refrigerant.

Then I'd just grab either a universal R/D (or the correct one locally/ebay) and stick some hychill in there. It would probably be about $15 of hychill and hopefully less than $50 for the receiver drier.

This happened to my wifes poogoe 407 recently. The compressor-> condenser hose split (stupid design of it guaranteed it would split). I ended up ordering in a new hose in through poogoe 'cos no-one could make up a suitable hose. It ended up costing less than $135 for new hose and $15 for refrigerant ....

Get this though The receiver drier is built into the condensor .... It was going to cost me over $850 to replace the condenser ('cos you need to replace the moisture absorbing desiccant in it). What complete ****wit thought up that system. The system was only open to the air for about 20seconds, so i ended up leaving it on the Vacuum pump all night (in an attempt to boil off all traces of moisture), then got it good and hot and recovered the the hychill, and vac'd it down again and refilled it. I really need to replace the condenser just incase there is traces of moisture in there .... but FFS .... $850 bloody dollars. That means even doing it myself it would cost over $1000 to fix a simple hose with a manufacturing flaw in it (gee's I HATE modern cars). There was still pressure in it when I removed the hose, so there is no way moisture could have found it's way in prior to replacing the hose. (the hose that was no good was discharge side, if it was suction side, it may have managed to suck air in ... doubtful though).

I would have cost me $400 all up to fit duel A/C to my Citroen CX ( system off a wreck, brand new super efficient condenser, new seals, new oil, new RD with trinary switch, drum of shellite to flush it all, hose bender to fix the copper lines that run under the car front -> rear etc..).

Hi Shane,
Its 97 Vectra, my daughter is saving for a European trip so at this stage a car is at bottom of the priority list.
I have found a compressor at a local wreckers for $110 but will only buy if it is still gassed.
The aircon guy wants $400 for a complete regas.

If your going to pay $400 for a regas, you'd be crazy to fit a 2nd hand component. Check ebay prices for a new compressor. It's going to be false economy to spend $400 and find the used compressor is no good

Hmmm... $550 for a new compressor... Now I see your dilemma. Do you have any mates with a vacuum pump and hychill that can 'vac it down and stick a squirt of gas in if you fit a used compressor and new RD.
