What is the ideal ambient air temperature for fitting a W123 windshield?

G'day Folks,

After much work I've traced leaks to leaking rubbers on rear and front windshields / windscreens on my 1981 W123 300D. I've bought new rubbers and I plan to fit them as described in the wiki.

However - and here's the problem - I'm stuck working outside. At the moment ambient air temperature is about -6 degrees C at night and barely goes above freezing point in the daytime. I know the thermal expansion and contraction of rubber, steel and glass are quite different - and I've heard stories of windscreens popping out of cars when it get really cold...

so

Question:-

At what temperature would you gauge it to be OK to start this job?

(I don't want to rip it all out and have to wait until spring time to get it all back in)

Ideal temp is 20C.

Your best bet woul be to keep the seal inside & remove the old seal & glass,
bring the glass inside & set the seal on the glass inside.

Then at the warmest part of the day install the new seal & glass as an assembly.

Windscreens pop out when it's very hot, not very cold. You can get a stress crack when it's very cold sometimes though.

Thanks for the response I've never seen it happen - but I can imagine that the steel contracts at a rate faster than the glass and so the hole in which the glass is set gets smaller - thus popping the glass out... it could be an old wives tale of course!

If it were to happen like that just think you could start off in your diesel in Florida say and drive north until your diesel waxes and your engine stops and then to top it all your sodding windshield pops out too - bummer...

Thanks a lot - I'll wait until it gets a bit warmer then.
