Holds breath waiting for constructive criticism......

Ok, I'll bite. Unlike bad monkeys vid on bleeding brakes which was very good this vid shows bad practice.

There is a recommended way to replace the pollen filter, but this is the bodgers way!
Although the method in the vid can work most times, it can also lead to issues where water enters the pollen filter, or passenger footwell in the cabin.
The problem with this method comes from the fact you are bodging the job from the start, so you are already cutting corners before you start. By simply pulling up the front of the rain cowl you are potentially disturbing it's rain seal at the base of the windscreen. When the single section of the cowl is screwed back down it may not seal correctly at the bottom of the windscreen due to dirt in the rebate on the trim at the base of the windscreen. This may only allow the odd drip of rain to hit the pollen filter or could allow enough rain in to ruin the pollen filter.
When looking at a car that's had this method used on it it's often easy to spot as they will be a poor seal at the base of the screen, and more dirt in the screen trim rebate.

Although the recommended method takes longer it does mean that the windscreen seal should be a lot better and that the pollen filter should stay dry and last longer.

The bare bones of the recommended method is:
Mark wiper blade positions of both blades on the screen with tape etc.
Remove both wiper arms.
Lift bonnet and remove both cowl sections, NOT just the one in front of the filter.
Clean the rebate in the rain channel trim at the bottom of the windscreen.
Clean the grooves at the rear of the cowl sections.
Clean area around filter, remove old filter and fit new one making a note of its orientation arrow.
Refit cowl sections making sure they fit correctly into the rebate on the windscreen trim piece BEFORE doing up any of their fixings at the front.
Close bonnet, refit wipers so that their blades match the tape marked positions on the screen.

It is a bit of a pain to remove the wiper arms, but this is a once per year job at most and it's important to clean the windscreen water seal rebate so is worth the extra effort in order to know the water seal is correct :)

With reference to the vid above you can see the cowl connection with the screen being separated at around the 1.00 minute mark in the area closest to the camera. You don't see it being put back together.

I probably sound too picky here, and if someone has never removed the cowls they might not know the trim I'm talking about.

It's the trim at the bottom of the screen in this pic. The rebate in it needs to be clean for the cowls to seal correctly, and once they have been moved they don't always go back in. There have been loads of threads on this site about wet pollen filters or wet footwells, and posters have gone to all kinds of lengths to stop their filters getting wet, but quite often the cause has been that the cowls haven't sealed correctly against the windscreen. The only time the seal will be disturbed is after a filter change, windscreen change or crash etc.

Looking at the above pic you can see there is dirt around a loom cable in the engine bay below the screen. That all got in there via the small gap between screen and cowl as the cowl hadn't re sealed correctly.
The area where it didn't seal can be identified by the section when there is dirt below the rebate in the screen trim.

Mmmn good points but honestly I've done this a few times by just flexing the cowl up a few inches for access, and I seem to get away with it. It doesn't leak. I guess if you're rough with it you could displace it off the seal. I do keep the seal and drain channels nice and clean though.

I've done it that way in the past too lol.
I'd also say that an awful lot of people are told to do it the way you did too.
It's just that here in the 'sunny' uk :) lots of owners get issues with smelly pollen filters (caused by water ingress) or wet footwells. There are threads in here on a regular basis and some owners have gone to massive lengths to waterproof the area around the filter, but that of course doesn't cure the issue as water is still coming in from the screen. :)
With the climate here a smelly/wet pollen filter is a really common issue with the mk3.
While there are jobs I do 'my way' I do the pollen filter change the Ford/Haynes way as the extra work doesn't take long and its only a once per year job.

As an aside, your camera work is top notch IMHO.

I posted my comment above, about criticism, from my phone before viewing the video.

Now that I have watched the link I would not entertain doing it the way shown, for the extra bit of time required to remove both access panels completely it would alleviate the need to do this job in a 'keyhole surgery" style and possibly not get every piece located exactly correct, I guess that they don't get upwards of a Metre of rainfall in New Zealand as opposed to sunny Bristol!

Note: just checked and I guess the poster has just been lucky not to have a swimming pool in his passenger footwell!
""The West Coast of the South Island is the wettest area of New Zealand, whereas the area to the east of the mountains, just over 100 km away, is the driest. Most areas of New Zealand have between 600 and 1600 mm of rainfall, spread throughout the year with a dry period during the summer""

On a bit of a tangent, how lovely and sunny has Bristol been today. It's been just so sunny today :)

I did like the way he filmed this..no shaking and clear.. although I changed my pollen filter the long way..
I doubt my big hands would fit..:)... didn't know Ford did a charcoal cabin filter for models with auto climate. the last filter I bought from local motor factors a crossland one which cost a tenner. read a post were the OP wasn't happy about the crossland filter can't recall what he said, but I've found it fine and the cab smells of the dangly black xmass tree I hang on the mirror,and nothing else....hate smelly cars...I never let anyone smoke in it ..myself uncluded... now where I can purchase one of these charcoal cab filters,apart from Frauds.:)

I did this job yesterday - the hard way. The biggest problem you are likely to encounter is removing the windscreen wiper arms. If they have not been removed for years you are almost certainly going to need some kind of puller to get them off. I spent about 10 minutes spraying WD40 and trying to rock the arms off and gave up as I didn't think this was doing them any good. So if you are in a hurry and don't have a puller you are finished before you've even started.

I only had a scissor action type splitter to hand and although this worked in the end it is quite dangerous because the bolt head is vey close to the windscreen and you will only be able to use a ring spanner or open-ended spanner on it. Also, you never actually know if/when the arm is ever going to pop off until it actually does. I managed to gouge some lumps out of the plastic cowl with my large adjustable spanner before I noticed I was doing it - but no real damage done. The other PITA with all this is the number of times you have to open and close the bonnet during the various stages of removing the wiper arms.

After the wiper arms are off the rest is really all about cleaning and refitting. The actual cabin filter itself is simple to change. When I refitted my cowling I wasn't particularly convinced about the effectiveness of seal with the windscreen, but I think it went back on where it was originally and the screw holes all lined up as before. I should have spent more time cleaning the windscreen edge, but was running out of time and patience by then.

I think it's pretty safe to say that my pollen filter was not changed in this manner the last time it was done, and I doubt any garage would do it this way unless you specifically asked them too. I also can't imagine a garage spending half an hour cleaning the cowling and windscreen edges either. It also begs the question - why is the cowling in two sections if you aren't supposed to be able to split it and remove one side on its own? I can see no other reason why it shouldn't be a single piece?

Hope this helps someone.
