Hehhehe.. mine does that too! It's an electric tensioner on the seatbelts!

When the car is running, pull on the drivers belt... it resists a lot. Turn the car off... CLUNK! Now pull the belt... it's smooth with little resistance.

I pulled the rear quarters off when I removed my seat and ran wiring for my stereo, and the belt rolls have an electric something on it, with Australian branding. So I dare say it's an aftermarket thing that was fitted.

I have a pic at home if you're interested.

Pretty loud, yeah!

I haven't had it for a while now, because my alarm's turbo timer keeps the ignition going after i've taken the belt off and gotten out of the car etc.

But yeah, have you tried pulling on it with the car running and not running? Could you feel the difference?

yeah there is like a tensioner that only works when the car is going.

Umm.. no, I didn't. I found it when I made my new parcel-shelf. This is why a couple of shots are through the rear windscreen. =-]

The second pic shows the location. It's kinda under the parcel tray, but adjacent to the rear seat.

Oh, there's that little box that noone knows what it is for! Sits in the left bracket under the parcel tray in Series2's. The same bracket on the right-hand side is empty. Something to do with fuel, apparently.

But yeah, the seatbelt tensioner! Way cool, eh!? Looks to be an Aussie thing done, possibly during compliance. I don't think there is any way to "fix" the noise, cause it's a mechanical device. You could try unplugging it and having just regular spring-tensioned belts.

There is still a spring in them like normal belts, so this should work, and the teeth that grab the belt if it moves a certain speed should still work too. Best to test this though.

The third pic is of the front passenger belt. I had the rear passenger quarter-trim off to fix some broken clips and to run some RCA cables. It too looks to be wired for something, but it is not noisy, only the rears in my car.

Hope it helps! I love gadgets!

No worries... i've never seen it in anyone else's car, and noone seems to have ever heard of it before, but from what you describe, it's EXACTLY what mine does.

VERY lound clunk, and that seat-belt tension thing is wicked.

yeah my first though was it had sumthing to do with the seatbelt tensioner thingy, but its hard to explain what it is to sum1 who has never heard it. my mate were like "WTF" when they first heard it.lol i didnt know what to tell them, just said it sounds like the seat belt thingy to me. :D

My 33 has these seatbelt tension thingys too... but they are connected to a wire under each front seat... looks like they used to be connected to the seatbelt socket thing. When the ignition is on, i can short the two pins on the blugs under the seat and there is the loud 'clunk' noise that you speak of. I've never really noticed too much of a difference between shorted and unshorted, but i'll have to try it out!

It sounds like yours are perminently shorted, so they always clunk when the ignition is turned off... try looking under the seats for a cord, and see if there is anything causing the two pins to be connected (the one on the passenger side is easiest, as it only has two pins, the drivers one has four.)

Okay, couldn't resist the temptation :rolleyes:

I went out and sat in in my car, turned the ignition on, and shorted/unshoreted the pins on the seatbelt connector... The belt seems to slide pretty much the same, although with the pins sgorted there is a slight ratchet-type noise when you pull it, whereas without the pins shorted it is quiet... I can't feel any more or less resistance either way though.

I think the "clunk" noise means that it's working, because mine will do it with ignition, and also if I press the seatbelt release button. Oh, and there is a definate change in resistance...

I think when the new compliance rules came out, the seatbelts had to be changed, whereas mine has the original jap belts according to the tag.

i have this also. i would've sworn black and blue it was hicas locking itself or something like that... i'll have a listen for the seat belts next time i have someone else near by to turn off the ignition. i'll jump into the back seat and listen... very interesting.

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      Blue slip

      By GTSBoy · Posted

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
