Having got excited over the prospect of getting over the compressor and alternator mount problem now overcome, I got on line and looked at air con kits at car builder solutions to see what they had to offer, and realised they had everything to make the job easy from here on.

About the same time as I was tempted by the prospect of spending £342 on a kit from car builder.com, I was delighted to receive my 80% of my last 3 years average tax payments due to the covid self employed thing, and yes I was very happy that I’ve always declared my earnings, so I hatched a cunning plan.....

As you can see, the alternator is a close call!
“Cosy” I’d call it..

Looks like the alternator grew there :D Amazing shoe-horning. A local hose-fabricator company for the hose-ends?

I’m assuming if you take the ends down to somewhere like Pirtek they can make the hoses you need.

I think Car Builder do a send off service too?

Looking at the Facebook updates, Drew did them himself?

So....looking at the kit that carbuilder.com, it comes with hose fittings, evaporator, filter/dryer etc, but I already had the kit that I’d previously bought second hand, so if I got it, I could do 2 cars! The original evaporator was long and thin, and would for under the Volvo dash nicely, but the new one was more dumpy and when I measured the scimitar passenger foot well, it would fit perfectly......so that clinched it, I bought the kit!

This is the second hand evaporator, and this is how it looks in the Volvo. I had to make a few brackets to mount it securely, but the all metal dash made that easy.

Now that the engine bit was done and the interior bit was done, my attention was turned to hoses.....(.efi, Phil Howard,)
Bearing mind that we were still in lockdown season, and the covid decorations were still up, I had been thinking about hoses, and getting it charged up , and decided to go about on my own.
Car builder (as been mentioned) do offer a hose crimping service for £50, plus postage, so you get the hose, set it all up, cut the hose to length and mark the position of the ends on the hoses, then send it off for a bit of crimpage. Bearing in mind that I may be having 2 sets made up, I looked on eBay for the crimping tool and found I could buy one for £100 including postage from Latvia, and it looked identical to the car builder one at double the price.
Amazingly, a week after purchasing it, it arrived!

At the same time, I bought gas (I’ll cover this bit later on, it not what you think😀) plus I bought a cheap gauge set to fill it up.

I got the hoses made up without any issue and got them fitted. I mounted the condenser rad at the front, again from car builder, but space is really tight again, so it’s quite small..

I fitted a foam strip between the radiator and the condenser to create a seal, not ideal for heat transfer, but there’s not enough room for a gap and a separate fan, so by doing it this way the original cooling fan pulls air through both. This car has never had overheating issues ( apart from when the head gasket blew on the m5 towing a big caravan) so I was reasonably sure it would be ok.

The next bit was the oil and gas.
Now the thought of going to some charge your aircon quickfit outfit and explaining to the 16 year old that I’d done it all myself wasn’t going to go well. Every experience I’ve had with any garage over the last 20 years generally hasn’t gone well. No doubt this is because I own 6 cars and the youngest being 25 years old. I have a friend who is a specialist in commercial refrigeration who gave me some pointers. But a lot of it seems is guesswork. Some of it is common sense. Filling up a production car it’s easy in that there are set amounts of oil and gas, for the specific vehicle...
you vac it out, check for leaks, add specified oil, and the set amount of gas for the vehicle. Simples.
But when you make your own, how big is the compressor? How long are the hoses, the evaporator, the condenser?

I did loads of research on gasses, the obvious one being R134a used on most cars, but it’s being replaced and will be legislated out over the next few years due to its ozone damaging properties, it’s replacement R1234YF is less damaging, but it’s still harmful, and it’s highly flammable hence a slow uptake by manufacturers of new vehicles.
I got onto the idea of propane...it’s an ideal gas, has great cooling properties,it’s cheap, and readily available and is used in air con and refrigeration, but it’s flammable! Letting it out has no damaging effects, so for me I thought it was worth a go.
A look on eBay and I’d soon bought Some tins of R290 and an adaptor to fit the tin and the gauge set.
