Hey guys just wanted to ask some advice. I park my car on a slight incline, so that the front is higher than the back of the car. Every time I start it in the morning, after a few seconds, there's a horrible screeching sound coming from the engine, then the screech stops, and the revs increase a little then settle down after about a second to the normal rev range for idle. I'm not quite sure what this was, i thought it was low power steering fluid or something so I topped that up, but now that that's ok I'm not sure, because if I drive off too soon, the moving off process causes some slight screeches too...thanks in advance :huh:

Sounds like a belt is a bit loose and when it sits it slides toward the back of the car and rubs up against something. Which belt is the scary part! Could be simple, A/C, Power steering or Alternator... or SCARY, Timing belt.

Get a Mechanic to check asap, or look yourself... but I'd say from what you've said you wouldn't know if the belt was too loose or too tight. So go the Mech :huh:

haha yeah you guessed right..I wouldn't know :huh: might wait to see what other ideas pop up then go ee him with a better picture

i'd say its just a belt slipping. and what is happeneing is that it is spinning for a second, then it heats up a bit and gets sticky and grips and gets on its merry way. very common problem amoung any type of car.

just go round and tighten all 3 belts slightly.

i hear that screaching noise every few months , i mainly notice it when we get some rain or a misty night , my opinion is it could be moisture getting to the belts? my opinion - im not a mechanic or anything , but i do notice it in those conditions . on my old car i got the same noise and sprayed some wd40 on them , would stop the noise , from happening in winter

Just a quick question (may be dumb lol) but how would i go about "tightening" the belts, i thought when they got worn out and started slipping you just had to replace them, can you extend the life of them?? Thanks heaps :(

I'd replace them, but I'm picky :)

First you'll need to identify which belt is lose, they all have a little bit of slack... but you'll notice if one has more then the others.

Then find the tensioner/pulley that is on a sliding hole (when you loosen the bolt it can slide along that hole). Then just slide it until it's reasonably tight. It's not a big deal, but just remember to be careful and don't make it too tight as to stretch/damage the belt.

Wet some soap untill it becomes like Jelly then apply to the belt.

PRESTO......no noise.

That may stop the noise, but wouldn't it encourage more slipping?

Soap acts as a lubricant, especially when moisture is added.

If you want to be that dodgy, you'd be better off pouring coke on the belts.

The fix for you...did this last week on my Maxima.

:sick:

Damn, that sounds like a good fix, might try it in a min :wave:

thanks for all the replies guys :spank:

When the soap dries it ends up being a dry lube.

Coke :spank: .....is only when u use Bourban......

Dodgy you say.....my mechanic recommended it.

Angry Fist.........Post up your results after you have lathered up. :sick:

The thing is you dont want to lubricate anything here. Belts arent supposed to slip.

Another cause for a slipping belt if its not just slack is it can be bottoming out in the pulley. Like i said b4 check for correct belt tension and signs of slip and replace or tighten as necessary

I recently had a loose fan belt that made the same noise until the alternator regulated output to 14V, then it would stop.

Tightened a smidge and it's good as gold. 5mm just like Deren suggested.

PS Using the soap is a good way to help identify which belt is causing the noise. Washing up liquid works ok as well. It saves replacing belts left right and centre.

Tighten it up, or as someone sujested soap as a quick fix to the annoying squeek.

I'd sujest dr y soap, just take a cake of the old "sunlight" yellow shit, and why yoru cars running put it on teh belt :) I did it when mym was winging about her commodore squeeking, and becuase i coudlnt' give two f**ks about that car i soaped it up :) when i took my alternator of for re-conditioning i didn't do it up tight enough so mine did the same, but i stayed away from teh skyline with the sunlight soap, i just tightened it up :)

Same happened to me yesterday - put your hand on the pullys of the ALt and Steering pump etc when MOTOR OFF and you will soon feel which pully is slipping from the temp, near burnt my hand on Alt pully. Sure enough belt a bit loose but not imeadiately obvious.

I loosened it right off first to check it was not the bearings though, then tiightened up.

    • Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
    • A 180SX has a much better look than a FD. The roofline is far superior being a fastback. It's popups look better. In a world where we all subconsciously add a little bit of low, and wheels of our preference, it's just more handsome than the FD is. The FD just looks 'bubbly' in comparison. It can come down to preference, sure. But "The FD is the BEST looking (on appearances alone) 90's JDM car without question?" Nah. Plenty of questions lol. I could think of 8 cars I think look fundamentally better, and probably a handful of ones that look about on par with a FD. (like say a SW20 MR2) I feel people like/overrate the FD because of it's mythicality/rarity, its rotary and it's unpredictable nature. It probably drives great, you can stuff a ton of tyre under there, has a unique sound, light as hell. I feel that people reading this thinking "YOU CANT RATE A 180 ABOVE A FD BECAUSE A 180 IS A CHEAP DRIFT BUCKET" prove the point about bias as to what the car represents, moreso than how it actually looks.. I feel the 80's boxy/squared off look is becoming better looking due to time, and 90's melted soap bar aesthetics have not aged well. (yet?) And this thread is purely about looks :p
    • A red or yellow S15 wins my vote, Ack that it just scraps in with the 90's cars theme, but they are great looking little sports car Next would be a A80 Supra (pre face lift), whilst the A80 has its own issues, I feel is the best looking larger GT car As for the FD, "I" feel that the reason it triggers me in a non-positve way when looking at one, is like looking at a high maintenance pretty girl who you know is mentally unstable and likely to explode for no apparent reason
    • Yes, it's because it has hips and bulges on the top/front surface, a tiny cockpit and roof, and the skin looks like it is stretched over muscle. The proportions are....perfect. Long nose, short rear, short roof. What's not to like? It continues the theme started with the S1, that peaked with the FC, being "looking like a front engined Porsche", while gaining a little more of the 60's Mustang coupe profile and stretching the skin more tightly over the understructure. The FD is definitely colour sensitive though. Like all Mazdas. There are plenty of details on it that changed over the years that were either better or worse, could have been done better the first time and/or never changed for the worse. But...the same can be said for the NSX. In fact, that's probably even more true for the NSX. I've also just worked out that part of the reason I don't like the rear of the NSX is that the integrated wing is too similar to that shitful R33 rear wing.  
    • I wonder if people like the FD because it reminds them of old 60's roadsters and such. It just gives me such a 'roadster/soft cruising' vibe as opposed to anything more hard-edged and purposeful. That, mixed with 90's melted soap bar styling. It's hardly ugly, but it's kinda oddly proportioned to me, relative to about 10 other cars I had a think about based on this thread.
