Clutch Fan Squeaking

When I start the car up in the morning, the clutch fan will squeak pretty loudly for the first 10-15 minutes of driving.

After 15 minutes it's smooth and you don't hear it at all.

Anyone else have this problem?

The car has never gotten hot, so it seems to be working OK. It's just embarrasing when your car is squeaking it's head off.

I've been thinking about going to a thermo fan, but if it's an easy fix I'd rather do that and spend the money on mods :)

Thanks

J

First check your belts, odds are they're too loose.

Correct tension is when you put about 10nm (approx 1kg) of force on the middle of the belt between the alternator and the water pump (fan) pulley's, the belt should deflect approximately 13mm.

I never do this check anymore, I simply tighten it a fair bit to get it streched initially then loosen it a lot till it starts squeaking. Then I tighten it two turns.

Pour a little bit of water on the belt in the morning, if the squealing stops immediately, you've found your problem.

Cool - I'll give it a go with the water and se what happends.

A few months ago I got the ****s with it and actually took it off to see if the fan was causing the sqeak.

But stupid me took the fan off (four nuts) and then started the motor !!! Forgetting to put the four bolts back on the pulley flew off at some supersonic speed !!!! :) :confused:

The belt came off too (of course) and the squeak stopped.

But I'll try the water trick.

Thanks

Haha, I did the exact same thing with my Torana many years ago. Luckily nothing flew off, just got very loose and made a hell of a racket. I don't think I ever ran so fast to switch my engine off from under the bonnet!

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?
