Leaking windscreens

Andrew you gan try running some sealant around the screen
But these seals are common for leaking with age most windscreen fitters will warn you when they fit a screen to one of these they usually prefer to install a new one

Hi Andrew,
Top of the drivers side about 4" from the side?- normal (new seal) especially after "real" off roading.
How did you go with the multi valve?

Andrew,
I know exactly what you are going through.
Check out this thread

Having fitted a new genuine rubber it continued to leak, and this had followed 2 replacement windscreens and numerous resealing by so called experts.

On trip to Broome we ran into a small shower at Barn Hill station and the leaking was still there.
Fortunately, it did not rain again until I was at Emerald in Queensland, and it started to rain again big time.
A minor flood resulted and I had to remove the plug in floor to let water out.
Went to local Toyota dealer but they could not help and referred me to local windscreen repair (Protector I think ).
Usual promise of I will fix it, which I had heard from every one of the previous repairers.
Said I was used to this but this guy said he had an 80 series and knew what to do.
After he had started he called me into workshop and showed me that there was no sealant on the underneath part of rubber at top of screen.
I said but that water does not run uphill and his reply was that" you would be surprised where it runs"
Anyway to cut a long story short I paid the $99 and have been through 8inches in one night and 28 inches over 3 days and not a sign of a leak.
So for what its worth check to see if yours is sealed on bottom side at the top.

hi all sorry dozer i am sought of going to hi-jack your thread i have a rodeo and have a water leak as well and it is drip onto the air con fan and burning it out so iwas wondering if this could be caused by a leaking windscreen.The water only tends to pool on the passenger side.If so how do i tell because my mechanic couldn't find where the leaking was coming from and told me to go to a panel beater also the leaking is gradually getting worse.

Had a similar problem on another car in the family.
Is it a bonded windscreen like the commodores?
The other car leaked too, but is not bonded, so bought a new rubber and put it in myself.
After taking the old one out by applying even pressure from the inside with my feet (the rubber was almost perished), it took me most of a day to clean the windscreen surround of previous sealants.
Then a small bead of sealant on the steel, slipped the rubber around the screen (what a pain until you got the knack), a wipe of kero on the rubber, two on the outside applying even pressure and a bit of cord inside, and it was in.
Hasn't leaked since.
The experts make it look easy, but I don't think they clean the steel surround as well.

In my experience there is no way to stop a windscreen leak permanently without removing the screen and doing it properly.

Gidday Dozer,

It depends where your leak is coming from. If it is in the lower part, you most likely have blocked drain holes in the scuttle or rubber, or both. That's assuming you have a self-draining rubber. Unfortunately, it's very difficult to clear a blockage without removing the glass. If you take that path, you'd be better replacing the rubber while you have it out.

I would suggest that your rubber has shrunk with time. There's not much you can do to get a permanent fix with a shrunken rubber. If you're going to use some sort of sealant, avoid hardening ones if possible (such as Sikaflex or silastic). While they are good products, they arent really intended for the task. You need a butyl type sealant which stays soft (you know, the one that's a pain in the ar$e to clean up).

Thanks everyone...all food for thought....i think i will look for a professional to mend it.
The water is seen coming from the glass where it mates to the rubber seal in the lower corner of the drivers side, and then runs off the rubber and behind the dash....my first thought was to get some sealant in between the glass and rubber on the outside, therefore steming the flow...but from whats been said, i think this is more than just a easy fix...
