Hey guys,

So I was driving to Victor Harbor one day when a puff of steam/smoke came out of my bonnet on the left side. I pulled over and had a quick look, car was still running fine. Later I tried turning on my air-con and found out it was completely dead- and this is why...

The pipe that's been blown open (no idea how) seems to be made of plastic, with some sort of silver insulation or something over it... does anyone know what that pipe is called? From general web searches, all I've seem to find is 'low side pipe (from evaporator)' and stuff like that, makes it a bit hard to track down a replacement. If anyone can let me know what sort of material it is, the name of it, or even better - where I could grab a replacement then that'd be awesome.

Cheers!

that is a rubber hose with the aluminium over it to protect from heat .it is joined by crimped joins onto the aluminium ends.must of gotten too hot and blew out,should be able to get one from a wreckers or somewhere like that.not sure if nissan would still sell them, be worth ringing them at least ,or maybe you can get the hose replaced by a hydraulic hose fitter/maker.. :P

it looks like that hose is awfully close to the dump pipe & turbo, and it has slowly burnt (and the hose is probably as old as the car too, so likely to have tarnished slowly over time).

I'm no expert, but it's probably pressurised aircon/refrigeration gas that you lost through that split in the hose while you were on your way to Victor.

if you want a genuine part - go into a Nissan dealer - e.g. Lakeside Nissan on Main North Rd near Mawson Lakes. They'll get the replacement hose for you easily. Although once you replace it, you may want to look at shielding it with better insulation, or modifying it to sit a touch further away from your dump pipe & turbo.

Since you say the aircon is completely dead now though, the problem may be greater. hope you get it sorted before the rest of summer mate :P

Thanks heaps for the feedback and quick replies.

The photo I've taken is probably a little deceptive, as the blown hose sits further down than it looks, but even with that said I guess it is pretty close. It definitely is burnt though, so I guess that's the reason it finally blew - I just would have hoped/expected to notice the carbon on the hose earlier! Hopefully the gasket is fine, but if I notice anything (or I see it's being burnt again) after I get a new hose I'll look into it.

I think you're right too, Luciano - there was a pressurised gas-like hiss when the steam/smoke came out, so I was silly not to pick up on it straight after it happened. Thankfully, the climate control (LCD screen, fan etc) still works and everything, I probably just exaggerated a bit when I said it was completely dead! The car revs a bit higher when I press the A/C button, so I'm pretty certain it's just that cheeky hose.

I'm just spewing because I've got a 6 or so hour drive to Tumby Bay on Thursday... oh well, windows down and I'll be alright.

Cheers again

I rang up the Nissan dealer on Unley Road (as it's closer to me), and they quoted me $344 + GST + 2 weeks on the part as it's coming from Japan. Youch! I haven't ordered yet (insufficient funds), but at least I know the figures.

Does anyone know of some decent wreckers that might stock some old R33 parts??

Hmmm, looks like until I get that hose replaced, I'll just have to put up with being a crispy critter.

You wouldn't be silly enough to replace the hose without first getting some heat shields on the turbo and that dump would you????

And switching on the compressor, not too smart. It will try to ingest the remains of your hose and assorted crap.

Aircon internals must be surgically clean.

Yeah that looks like the one I'm after. How much do you want for it? Though it looks a bit corroded or something... it's not clogged up or anything?

yeah its been siting around for a while but its clean inside, if you were in wa id say just come and get it , aall id want for it is enough to cover the postage , probably 20 or 30 bucks, im not going to use it again, its up to you, pm me or whatever,

Yeah it's unfortunate that I didn't see the hose had blown, so when I pressed the A/C button it's not like I knew it was a bad move. Depends on the price of heat shields etc too, if I put on a new hose and there's no burning, then I won't worry. If there is, I'll chase some up. Being a student means I don't have as much flexibility with my cash as I'd like. Ideally, I would get new/genuine parts from the dealer, but economically I just can't.

No worries dude, I'll pm you.

EDIT: Craig, I can't pm yet as I haven't had a total of 10 posts. I'll pm tomorrow when I've got some time to comment on a few other threads. Just got back from a big weekend away, so too tired to do so now.

  • 2 weeks later...

Got my mate who actually knows what he's doing (unlike myself) to give me a hand, and voila! Fixed. As you can see, I bought a roll of head shield and wrapped it over the dump pipe. Hopefully that does the job!

Air Con Fixed

Though it'll be good to get a really hot day so I can really give it a whirl.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
