The Silver part on the top/around on the outside of the car is like a bolt that you have to unscrew(not like a normal screw that you can use a philips head), you have to do with by hand someone or get a flat head screw driver to try and buge it. Its hard to explain..but as soon as you get the top silver screw "thingy" undone the arieal comes out easy.

Hope it help. Cheers Rob

If you only want to remove the antenna mast & rope, not the full assembly (assuming it is an electric antenna:

Remove the top silver nut thingy - this secures both the antenna to the body of the car and the antenna mast & rope inside the antenna assembly.

Get someone else (or your stereo remote control) and turn your radio on. Antenna goes up. Hold the top of the antenna mast to prevent it going back in and turn the radio off. The clutch inside the antenna assembly will slip as it tries to retract the antenna.

Turn the radio on again and it should push the antenna mast out the rest of the way followed by the nylon rope. If you cannot pull the rope out of the assembly you may still need to do the radio on->radio off cycle again to make it further release the rope.

A few points:

1. The "rope" (just a length of flexible nylon rod) should have teeth down one side of it that engage in the clutch mechanism. If you notice that there are no teeth, the mast is most likely non-replaceable. The assembly may have been replaced at some stage for a non-genuine one as every Nissan antenna I've seen is of the replaceable type.

2. MAKE SURE YOU TAKE NOTE OF WHICH WAY THE TEETH FACE! This can be the cause of much anguish...

3. There should be a copper or metal collar that slips onto the mast before you reinsert it. Make sure the old one comes out with the mast, or fish it out of the assembly before you put the new one in. This a) holds the antenna mast tight in the assembly and B) is the only contact for the signal path so ensure it is there/undamaged/clean to have a trouble-free antenna!

Reinserting is the exact opposite of the above procedure, line up the teeth in the direction you saw them come out, push the rope into the assembly as far as you can, turn the radio on, Watch your fingers! You may need to cycle the radio on and off a few more times whilst preventing it from coming out - it does take a few goes to get the clutch into the right spot so it goes up and down properly. Enjoy!

A few final points:

1. Manufacturers love making money on broken antennas. The prices OEMs charge are sky high! You should be able to get an aftermarket one at a good parts/car audio store.

2. All antennas require a good ground plane. Your radio antenna will be expecting a good ground through the coax shield (this should be a good ground to your radio anyway), through a ground strap provided on the assembly and/or through the metal assembly of the antenna itself. It's this last one you've got to watch especially on non-automatics - some manufacturers don't include a ground strap, and rely on the metal antenna assembly cleanly contacting the underside of the vehicle body where the antenna hole is cut. After many years this gets dirty and rusty, and people wonder why their reception is awful. So think about this when replacing your antenna and you should have trouble-free reception for years to come.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
