Are the 940s prone to rusting in any particular areas of the body? Thx much.
The series isn't really ancient yet, but I don't recall seeing a single rusty 940... -- http://www.albany.net/~mjc1/index.html
same here...can't say i ever saw one rust...... i would guess one back east, with > 300k miles on ought to tell us...
I thought they were galvanised, anyway most of the older volvos I've had did't start rusting untill at least 10-12 years old and they were not galvanised.
Same story here. 1992 wagon with no rust. When I cleaned it about two years ago using a high-pressure nozzle a chip of paint broke off from the left front door. I applied a few drops of paint, but no rust seems to develop. That's the only visible damage to the paint after 11 years on the roads, with salt in winter. It has been taken care of, but not meticulously. The 940 (and later 740) bodies were made from zinc coated steel. I don't think it is correct to call it "galvanized", because that usually means that the steel has been dipped in melted zinc. For car bodies I think the zinc is not so thick and gets applied in some electrolytic process. Volvo are not alone with this material. Audi were the first I think. Did you see a rusty Audi from early 90's? Our other car, the 240 has had a lot of welding done to it by a previous owner. Too bad Volvo did not make the 240s of the zinced steel... The hood on all 940s and the rear door on the 940 wagons _never_ will rust, because they are aluminum! It does not rust, but corrodes in other ways. Occasionally you see 940 wagons with paint chipping from the rear door. Aluminum is supposedly harder to paint. Even when the paint falls off, the rear doors dont go brown, the bare metal is greyish. -- Gunnar 240 Turbo Wagon '84 200 K Miles 940 Wagon '92 150 K Miles on Swedish roads
I heard 240 where galvanised from the middle of the doors down. My 300 series from the 80s were electro-zinc but did rust eventually. Galvanised lasts much longer. Doing a search on volvoclub shows exerts from brochures quoting 65%-80% of the body is galvanised in the 80s. Apparently floor panels where galvanised on 140s. Bare aluminium can corrode bady, but usually in the presence of steel in an electro chemical reaction. The al gearbox mounts on the 360 eventually splits and drops due to the steel cased bush that bolts onto it. Takes about 10 years. But yes generally al is less active than steel.
Because there's more to the internet than hits alone, Gunnar Eikman wrote: Can't comment about 940s, but the bonnet (hood) of my 740 is steel. The tailgate is ally, though, as is the sunroof panel. IIRC the petrol flap is plastic. Certainly is. The reason naked ally doesn't crumble away to corrosion in the same way that steel does is because it very quickly gets a very thin surface coating of oxide (corrosion) which 'seals' it against further corrosion. Unfortunately, this also makes it difficult to paint, since it is very hard to get paint onto the ally without there being an intermediate layer of oxide. -- Stewart Hargrave I run on beans - laser beans For email, replace 'SpamOnlyToHere' with my name
