Converting Air Con to Hychill.

Howdy

Replacing the aircon compressor on my patrol so will need to have it regassed.

Thinking of doing the change over to hychill so I can do it myself as I can get the gas and charge hose for $130.

Anyone done it before and have any tips?

Cheers

Yes, have done it.

One thing to consider is the suction hose. Hychill have an article on reduced barier suction hose leakage. Hychill recommend replacing these hoses. Also do the o rings too.

Perhaps as a 1 off it won't be cheaper. You need a vacuum pump, manifold set, scales etc. Purchasing them will come to more than getting a regas.

Have done it on my own cars and a couple customers, can recommend, cools better than R134a,

First car I did was my LV Focus, that thing was terrible typical Euro junk, above 30 degrees ambient temps you'd be lucky to get 17 out the vents.

Gassed it up with Hychill and 1.6 degrees out the vents:





30% charge by weight compared to R134a, probably not a concern on a Patrol but it wont work on shitful Euros using pressures to control the AC output as it operates at significantly lower pressures than R134a.

Don't bother buying the gear, just find a local workshop who does hychill I got a set of charge scales on sale recently and those alone were $220.

Did it in my EF as well, 0.7C out the center vents.

I don't have a vac pump unfortunately, I've got the gauges and the scales, the vac pump is the next piece of the puzzle, I'm slowly piecing together all the kit to do it again

You need to pull the system into a vacuum for a while, then let it sit to see if it maintains it before you charge it.

You'll be able to get it done for around $200-$250 I reckon, its just a challenge finding a workshop that will use it because there's was a huge scare campaign on behalf of DuPont who has the licencing for R134a to scare people off using alternatives (that work way better and aren't under some ridiculous licencing system courtesy of the retards at ARC).

TaT which is a local automotive aftermarket group also carried on about flammable refrigerants, but both TaT and DuPont seem to be rather quiet about their flammable replacement for R134a - R1234yf.

If you contact HyChill they'll be able to put you onto someone they know who uses it, they used to be fairly active on the internet trying to dispell propaganda spread about their product.
