Squealing Sound When Starting Car.

So I took my R34 n/a to the track for a day, the next day when I started it there was a loud squealing sound coming from the fan belt, I think it was the fan belt.

It only happens on a cold start, sometimes it'll start up straight away, other times i"ll have to turn to car on once or twice for it to go away. On idle and when driving I can hear a slight noise coming from the engine which was never there before.

The belt it pretty tight so I don't think it's a loose belt. I'll be taking it to the mechanic as soon as I can but if it's a simple fix I'd rather save my time.

Anyone have any ideas?

Thanks :)

The belt may be tight, but it may have been slipping whilst being thrashed at the track, which can result in the pulleys getting glazed. Makes them squealy under various circumstances (like cold starts, heavy loads from PA, alternator, whatever). Sometimes you need to rub the inside of the pulley sheaves with some sandpaper to clean them up. Sometimes all you need is a squirt of belt dressing.

If you want to test if it's the fanbelt, get someone ready with a squirt bottle ready to shoot the belt/pulley with water at the instant to start it up. If the squealing dies then it's the fanbelt. Otherwise it could be as described by Mike.

Thanks for the suggestion, I'll give them a go and see what happens and report back :)

Is the noise high pitched? I used to get a noise on starting, it went away after I replaced the coil packs on my N/A R34.

Yeah it is pretty high pitched but when listening it does sound like it's coming from the belt. It hasn't happened in the past 24 hours and I've drove it a fair bit so I'm not sure. I'll wait and see if it happens again.

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).

      Custom titanium intake

      No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here.

      I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p

      Got just the wing painted and fitted up to the existing boot. Big visual change and about time after having a GTR wing sitting in the shed since 2018 Headed up to Mallala with a quick obligatory stop in at Boliver OTR Oil control mods seems to have worked. I checked the catch can after session 1 and there was a dribble of water/e85 with barely any oil in it. After session 2 and 3 there was almost nothing and I stopped checking after that. so either great success or catastrophic failure/block of the external breather The GTR wing made a noticeable difference in the 160-185km/h sweepers. It was a very hot day for the cars at over 33C but the previously done cooling upgrade/ducting/water sprayers meant I never saw over 60C intake, 105C water and 100C oil and temps would drop back down very quickly once I shut it down. AD09's are a decent tyre but certainly and expectedly a step down when compared the the CR-S/AR-1 I have had on the car for years of track days. The handling characteristics of my car which I often describe using the Tony Hawks Pro Skater balance mechanic where either side of the center is understeer/oversteer was much more pronounced with no "green/safe" zone in the middle. However, imo it steers well/easily during oversteer largely thanks to the custom ACOSTAL front end. Enjoy a loose lap POV with my mate giggling away as a passenger.   Group photo for Peer Pressure Racing made it back home and gave it a wash Overall a great success compared to my previous two track days where i cooked the Starlets motor and blew up the new diff in the R32
