Drafty Ducato 160MJ Doors

[claydon59]

Been away for the first time this weekend with our new toy and I was amazed by the draft coming in though the windward side cab doors when travelling, it nearly feels as though it is coming in through the speaker grills and it is very noticeable, anyone else have this or even better a solution ???

On a coachbuilt motorhome, there is a pressure drop on the outside of the cab doors due to the aerodynamics of the shape. The doors have negative pressure and try to open. They all do it.

Ordinary house hold draught excluder is supposed to work ( the kind with the adhesive side on it). You might be able to get some adjustment on your door catches to minimise it

Hiya Claydon, I think these "speaker grills" are actually safety air vents designed to let gas escape safely in the event of a gas leak, the footwells in your cab and habitation doors are the lowest point at floor level and I believe the propane/butane gas is heavier than air so drops down to the floor.

I can,t think of a solution to your problem but I will watch this thread with interest cos I know someone will have an answer.

Good Luck

Don't know if his applies to your new toy, but on our '95 Boxer there are ventilation grilles in the trailing edges of the cab doors which can let a draught through. Mine are taped up now

I was told the same Lenny by my local dealer.....furthermore they suggested that the skylights still ventilate when closed and are designed to do so for the reasons you outline.

I must be honest my biggest issue is with my door, it has a louvre and if the wind is blowing wrong direction this time of year bloody draughty.

FWIW I had a gas leak earlier in the year, a faullty olive on a repair. I lost all the gas from my bottle but still here to tell the tale

Assuming that we are talking about the same grilles / vents in the cab doors, they are nothing whatever to do with gas. They are for ventilation of the cab when the cab is either sealed off from the rest of the van or is the cab of a chassis / cab unit. We are talking commercial vehicle design, not motorhome design. Commercial vehicles do not, as far as I know, normally have bottled gas in the cab.

Cold Ducato

Hi , I've got a 2005 ducato coachbuilt it blows like hell though the cab doors I put some draft excluder around it, helped some , but I think Taiping up the gills mite be a good idea, I also found a draft comming from under the dash board got my head under and found with the bonnet open I could see glint of light, looked like it was coming from between the main bulkhead and the side panel ,not sealed up properly ?.
I've an Adria and where the cab is joined to the the body at the bottom it no been sealed and the draft blows out of the seat belt adjuster slot, and my van is supposed to be winterized ! as long as i take so good warm clothing along I'm all right, its OK in the summer.

There is no insulation material inside the cab doors. I have heard it said that fitting Rockwool type insulation in the doors cures the draught problem from the grilles.

You need to be careful I would think as there are moving parts inside the doors.

I have a 2.8 JTD and taped up the vents on the side of the door and this made a considerable difference.

I think, and I have no knowledge, that the speaker vents are what they are, as this is just a standard vehicle cab modified for a motorhome. Grateful if somebody can substantiate

You will find if you look underneath the van the door pillars are open to the elements, tape them over with some clear polythene and stop the draft through the safety belt holes.

Also block off the 'speaker grille' vents.
