Where to drill the extra drain holes below dash?

Mr Otford · Nov 22nd, 2016, 18:59

The forum has a large number of threads about water sloshing around in the bulkead area and many contributors mention drilling additional drains in the area of the front wheelarch(es) and there is one posting of this link http://www.volvocars.com/en-CA/Publi...dshield_CF.pdf (which seems to be broken).

Does anyone actually know where the holes are drilled?

My V70 had the sloshing sound - which has gone - but is now without heater, HRW or heated seats.

I'm trying to find out the same thing, been to Volvo main dealer a few times, they have pictures of where to drill but they won't let me have a copy of the pictures so when i've removed the wheel arch liner, it has been difficult to know exactly where to drill the hole(s) I will be speaking to one of their technicians who has actually done this job and while I had the wheel and liner removed, took some pictures of the inside area so hopefully this tech guy can show me exactly where to drill. I'm surprised that this information is so difficult get, posted a few threads but no joy so far, will post here once i've drilled these holes succesfully, please share if you find out more.

Certainly I will post pictures if I find out where the holes are drilled.

Finally drilled these holes today, water poured out. Been a real pain to find out exactly where to drill, drilled some in wrong place, even with pics it's not that clear.
Once i've found out how to post pics on here i'll try to explain how to go about doing this job to anyone who is interested.

Excellent news Tim

My V70 is going in to the main stealer for an unknown proportion of the climate control unit to be replaced at vast expense next week. It's hard not to think that it has died because the slopping water has now gone . . .

In the last year it has had the following bits replaced: EGR box, alternator, drive belt and tensioner and wastegate. All that on a vehicle that has barely covered 60,000 miles doesn't make me want to buy another Volvo :-(

It may be that it is now a quite attractive purchase by a member of the caravan haulers association but I, quite honestly, want shot of it.

Maybe your water issue is different from mine? On mine, water gets into the bulkhead due to poor windscreen to body seal, there are no electrics in there as far as I know. Drilling the holes to drain this trapped water is not the cure, the cure is to have the windscreen removed and re sealed. Sorry to hear of the issues you are having but I have found Volvos to be awesome cars although the jurys out on the S80 just now.

I'm struggling to get any sense out of a main dealer with this issue. Has anyone got a diagram for this please.

There is a post on here somewhere with diagrams you need . I checked it out a few years ago when my sons V70 had the problem But the search facility on here is a bit of a tricky thing . Keep looking and you should find it . Good luck

Hello,

Do you found the correct info ? I need to drill them on mine as well.

At the moment I am in the process of drying the car and this took time. However I will still have the water somewhere in the front chassis.

Also I noticed water ingress throught in the luguage compartiment by the air vent ! Anyone else experienced that ??
