I have this whining typenoise coming from the front left of my engine bay

I think it could be either the power steering pump or the air con compressor perhaps?

Anyone have any idea?

chris

does it do it all the time chris?

Mine used to make the scraping noise when turning, turned out to be a ps pump leak (low fluid)

Now it makes a scraping from the same area only when the aircon is switched on. I need the aircon compressor rebuilt (new bearings, maybe clutch as well)

Yeah, I think its the air-con, as I have been using the de-mister quite a bit recently, it gets louder with this on

You reckon thats what it is? After about 2 mins its almost not noticeable, when I start it, its louder

PS Fluid level seems ok

could be. Drop in to an air con place and get someone to have a quick squizz is the best bet.

There is also the aircon belt adjuster bearing under the front left, which mine was making some noise. stick yer head under and have a listen if its that as well..

If you think its the air cond pump, disconnect the belt and see if its quiet . Power steer pump would be noiser when under load, like when you are turning the steering especially on full lock.

Whats the easiest way to disconnect the belt?

Get under the car and loosen the bolt on the adjusting pulley then keep turning the long adjusting bolt until the belt is loose.

Had a more detailed look last night

Definatley coming from the aircon compressor, and a bit of noise coming from the adjuster pulley as well

How do I remove the belt? Looking at it, I'd have to remove the power steering pump belt as well to get it off?

Thats what I am trying to find out!

by the looks of it, its just a matter of backing of the belt tensioner and slipping the belt of the compressor, but to get it out, it looks like you have to take the power steer pump belt of too

Trying to find out a answer before I dive in and give it a crack

If it's anything like the R33, then yeah, the belt comes off after you undo the LOCKING nut, then undoing the tensioner bolt.

From there, the AC belt is closer to the motor than the psteer belt. (on the harmonic balancer) so you'd have to do the same process to get that belt off so you can completely remove the AC belt.

On the AC, the locking bolt is the one facing forwards, at the top. you can get a socket onto it through one of the holes in the pulley. Without doing this first, the tensioner bolt shouldn't budge.

Might want to post pics, and then we can confirm. I still think it's strange how people buy cars with all the good bits, then remove them (hicas, AC etc) =-[ On the racetrack, I understand, but for a daily driver... =-o

The reason I want to take it of is to see if it stops making the noise first. Anyway, its winter, so I can get my aircon fixed well before summer comes around

All fixed, turns out it was the aircon tensioner pulley

Replaced it on the weekend, and it sounds fine now.

Interestingly enough, when I took the old one off and comapred the two side by side, the bearing in the one that came of the car felt reasonable, I showed my dad and he said to spin it with some load on it, and sure enough you could feel the bearings grinding away!

Very happy, was easy to do as well!

Chris

Yeah, I asked the guy at the wreckers about that, he said that most people end up damaging the pulley. I might have a crack with my old one, and if it works, there will be a pulley with a new bearing up for sale

    • Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.
    • The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.
    • Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?
    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
