Hello.


My fan shroud is broken. Jan 69 type two engine. I would like to start by finding out exactly what it is made of. If I learn that then it might be possible to repair it with similar comparative materials. It appears to be A.B.S. Luckily it is going into winter and I can presently drive distances without detriment.

Can anyone please help with either a shroud or suggest a method of achieving structurally sound repair?

Thanks in advance. Nick.

Talk to a dedicated plastic welder perhaps? They should be able to ID the material. Or perhaps a fibre glass specialist.

I have successfully cut up and stitched pieces into an ABS dash using not much more than a soldering iron but the issue is hiding the repair if thats a concern, it wasnt for me since I was filling, sanding and spraying with stone guard (piss weak spray can stuff for texture, not the proper goo) but it might be a problem for a car where such things matter.

I did some digging for you.

Which shroud is correct for your car is really a mystery. We know the December 1968 cars like Wayne's that were designed for a 1968 Chevrolet 327 but were fitted with the 1969 Canadian 327 were a bitza, and the shroud on them is the relatively common polyprop one the same as what was fitted to 307 but butchered to suit the later radiator. GMH then had a shroud made to fit that I believe will be 'glass reinforced like the other low volume shrouds (although this is not proven as yet). No-one is really sure exactly when this one became the fitted part, and given your car is an Acacia Ridge build where very few cars were made you may never know. GMH appeared to have had the high volume shrouds made in the tens and hundreds of thousands made out of polyprop and the shrouds they only made in the 100's out of 'glass (like HK-HZ 6cyl with A/C or HT-HG 350) - I think the later GTS327 shroud will be like this but not certain at the moment.

There is four options I can see for you:

1. Fix yours, it will be able to be welded and sanded like a wizbin.
2. Find a HK-HT 307 shroud which is what yours is, but it will require you butchering a valuable shroud which might see you lynched by GTS327 or 307 powered HK-HT owners!
3. Rare Spares had a faithful polyprop replica of the HK-HT 307 shroud but it was missing the part number. There was 1000 or so of these made so there will be one around somewhere. Butcher one of these, you could even stick the part number onto it.
4. The current Rares shroud is 'glass, and it will probably look correct for a proper GTS327 with full type 2 bits as it is a shiny, smooth finish, but it will also most likely have to be modified like yours is for the lower hose. These are very cheap.

I suspect that is your original, are you able to attach an image of yours? They won't be different between assembly plants as virtually everything for each assembly plant came from the same sources - GMH procured everything on contracts or built stuff in one location to send out to the VAP's and BAP's. The differences are how things were put together at the BAP and VAP as in how panels were welded to make the shells and how the paint was applied and when it was applied. It may be that one VAP was in front of the other schedule wise so you see the proper type 2 shroud at one VAP ahead of another VAP though, but you'd only expect this to be a short period - like less than a week.

Just add them to an album, then attach to the post.

Google : Plastic Welders repairs fabrication. As somebody has already mentioned. They can Repair any plastic you bring in. Ring one or 2, they’re out there.

That EPL revision tells us the new fan shroud was not used in production prior to the revision date of 21/01/1969.
The EPL and any evolutionary revisions always comes first otherwise the assembly line does not know which parts are required to build a specific model and variant.

I am going by what an ex GMH engineer explained to me about what an EPL is, how to read it and it's importance to the production process.

the cost is horrendous, hardly worth it it IMHO
