For some months I've noticed a damp patch ( :eek: ) wait for it, wait for it! ,,,underneath the car. On checking it, it's always just been water.

I thought I had checked and cleared the drains in the scuttle months ago whan I first acquired the car, but this evening I had a little look behind the engine and could see a braided pipe that looked wet.

On further investigation, from what I could see, the wet looked to be dripping down from above the pipe, so I groped around to try and find the source and felt something like wet mud hanging down! Wet mud it was - I pulled a load of it out and there was the sound of water pouring onto the ground under the car. I could feel a hole ( :eek: stop it!) with a rubbery edge to it as if something was broken, and indeed it felt like a lump of something was floating around inside the hole.

Long story short - I found two drains that were quite blocked. The left hand one felt like there was a great lump of something blocking the hole. I pulled it free and it turned out to be a strange shaped rubber boot.
I went back to the one on the right hand side of the scuttle and pulled a similar rubber boot out from there too.

Both boots were not torn as I had first thought but had a strange set of cuts in them. They were very clogged with dirt and quickly cleaned under a running tap. Clearly designed to catch and restrict debris, but quite honestly I couldnt see the point of them (hence the title of the thread)

I shall have to give the scuttle area a darned good clean out with the hose at some point, and once I've cleaned the area thoroughly I suppse refit these two boots - but what are they for?

Why not just allow the dirt, leaves, and debris to wash out through the holes unrestricted by the rubber boots?

Huge thanks Tim!

Makes good sense, although I would have thought that would have to be one hell of a vacuum to get them to close!

I will clearly need to fit them back in carefully and make sure they are properly engaged around the edges.

As I found them, they were totally blocked with muck and one was completely dislodged. Could that have happened with the pressure washer I wonder?

I'm sure as an aircraft engineer I can apply my "fit-things-into-impossible-places" skills and get them back in neatly :D

Thanks again Tim
 
They do need cleaning regularly as when they do block up they allow the plenum to fill up with water which will find it's way through the heater and spill out in the footwells.

They do pull out and wiggle back in place from within the engine bay if you can bend your wrist backwards, but don't push them all the way through, otherwise you'll need to dismantle the scuttle panel to retrieve them.

Just hold the split "bill" part tightly, push them up into the hole and wriggle them downwards until the lips seat.

Well known issue and well covered by many previous posts. Sadly many make reference to 'milking a goat' after I made that analogy in the past!


The easiest way to get everything clean and to re-fit the drain 'things'* is to remove the plastic panel between the base of the windscreen and the bonnet. (* they were referred to in older posts, especially about the previous 169 model, as 'duck bills' as they used to be shaped more like the 'beak' of a duck billed platypus)

This is easy to do: remove the wiper arms (first, pulling away the covers that shroud these - pull from the right-hand edge as you see them looking standing at the front of the car and they just unclip), then remove various plastic plugs that secure the panel. Once all the clips are removed, lift the edge of the panel nearer the engine and find at the left side the pipe to the washer jets, which can be pulled away. Then, lift the panel up as far as you can which disengages it from the base of the screen. By 'distorting' the panel it will pass out over the engine, around the bonnet hinges. Cautionary note: if you have a heated screen, beware the connections to the bottom of the glass which are very fragile and cannot be disconnected. These have bright blue plastic mouldings attach the wires to black foil tabs at the base of the glass -- the blue bit cannot be detached and trying will break the hair-thin wires in the foil part.

I'll find links to previous posts to help you.

Thanks to all that posted about this

I have one last question; when I removed these I had no idea what they were for - I knew these must be the drains from the scuttle by the type of debris I found - but I paid no attention to their correct orientation.

So when fitted, are the lowest points of the duckbills towards each other, or away from each other?

I can't see that it matters too much, but if the factory fit them a certain way round, there may be a reason for it.

I believe mine both have the lower end towards the driver's side, although to be honest I doubt it matters too much.

On the Puntos.. FIAT modified them..as the original dumped all the rainwater on the alternator.

So direction could be termed as Important ;)
 
My mums Renault scenic was an odd car. Top of the range she'd proudly announce.

She got it for a steal, an ex demo vehicle, a showcase for Renault UK. Had panoramic sunroof, air conditioning, and power windows all round. She loved that car. I think we'd all agree though, it was just a Renault.

Whenever you were in the car, you could clearly hear water slushing around, regardless of weather. Mum explained this as the windscreen tank, or the radiator, but, it was pointed out that the sound was all over the car. At the rear, top left, to the front. It sounded and felt like you were in a badly made submarine hurtling precariously down the motorway, captained by a driver who only notices flowers, ponies, tearooms and any puppies. To heck with cyclists and other road users.

It got so bad I decided to take a drill to the frame of the vehicle. 4 holes were made in the underside front and rear of frame. Each delivered a white cloudy liquid that didn't stop for what seemed like 20 mins.

Mum asked why Renault had filled the car up with milk. Of course. Why wouldn't they?

God knows there it came from.

Be glad you had some bungs to remove to alleviate the problem!

Wow that sounds incredible - I imagine there was a marked improvement in acceleration and speed after that lot was drained!

So what exactly was that cloudy fluid do you suppose?

Not much of an improvement. It was still a Renault scenic!

The white stuff must have been some kind of anticorrosion power thing mixed with water at a guess. Or mum was drug running in the car under the guise of an upstanding Womens Institute member with national trust sticker on the boot...
