hey i have a question about the r33 gtst aircon hose, the big one that has a silver insulation over it and goes from the firewall to the compressor, i read that a series1 hose does not fit on a series2 and i was wondering if anyone knows what is different with the series1 hose that makes it not fit on the series2 cos i need a series2 hose and i want to know how to tell by looking at it if its a series 1 or 2 so that i dont get the wrong one just in case the person i buy one from doesnt remember if it was a series 1 or 2 hose or it gets mixed up.

if anyone can help i would really appreciate it thankyou ...

Hi Mick,

I have attached a few pictures showing the difference between R33 GTS-T S1 and S2 Air conditioning hoses that connects from the vehicles firewall to the A/C compressor housing. I have marked the S2 hose in all pictures listed.

I have a set of S2 hoses and a S2 compressor for sale all fully working if your interested images below of actual items.

The difference between the S1 and S2 hoses are that the flanges/connections on the end of both hoses top and bottom are significantly larger than the S1 hose not only that but the "O" rings sit into a groove on the S2 hoses meaning if S1 hoses where used on a S2 compressor it would leak as the "O" rings on a S1 hose would not seal properly on the compressor side of the A/C system.

Thankyou so much for your reply, you put in alot of time and effore getting pics and marking them and you explained it really well to me. Thankyou again this really helped me, i just brought one just before you replied to me from a guy, i havnt received it yet and i was a lil worried about if it was the right one at first but after seeing your reply and the photos i compared it to the photo the guy sent me and thanks to you i am now sure it will be the right one.

You done a really good job on your reply mate and i think you would be awesome at doing diy tutorials and stuff

Hey guys, I've got a series 1, and I installed a series 2 compressor (was told it was series 1 when I bought it) and didn't notice the different size connectors until it didn't hold vacuum! lol. I was just going to get a series 2 hose and put it on there, but by the looks of those pictures, the firewall end of the hose is different as well? Do you think I would be able to take it to someone and they could cut off the ends and swap them over? Or would there be another way around this?

Also I only noticed it leaking from that one hose, but can anyone confirm if the other hose is still the same? Its the one from the compressor to receiver drier (or to the condenser, I can't remember off the top of my head)

Thanks in advance!

You wont be able to cut off the ends and swap them over as there is no way a welder can weld such small pipes and if they manage to weld them its unlikely they will hold the A/C pressure for long, that was the advice given to me by multiple welders/mechanics.

Solution: Purchase a series 1 compressor (while you have it in your hand i recommend inspecting the bearing and changing it if needed) then simply remove the series 2 compressor and bolt the series 1 compressor in its place and use your factory series 1 A/C lines running from the A/C compressor to the firewall.

Tip: Replace all your A/C "O" ring seals while everything is disconnected ;)

Thanks for your reply. Hmm thats what I thought, but didn't want to hear :/ lol. Yeah I'd rather not go down the series 1 compressor route because I've already bought and put in the series 2 one, but I might have to. Would there be any way to join them where the rubber hose in between the two ends goes? It's kind of hard to explain. Im not sure if its crimped on or how they join it?

You can take the pipes to your local welder, ac specialist, mechanic etc... and ask around or give them a call.

In my opinion you have 3 options.

1. Swap to a series 1 compressor and A/C lines.

2. Remove and change evaporator unit to a series 2 (two silver pipes / connections coming out of the firewall)

3. Visit an aircon specialist and get them to make you custom made pipes from the A/C compressor to the firewall evap unit.

I know which one i would choose...

Yep that seems fair haha. I might ask around about the joining of the pipes, but I dare say you're right, and Ill end up having to get a series 1 compressor. Cheers heaps for your help :)

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
