Cornwall to Scotland and back again...since that trip 18mths ago the engine hasn't worked right since. That must be the reason why aluminium things started melting. Plus the fact that the previous owners had disconnected the oil temp guage says alot!

I'll stick a kenlow fan in the back and make somemore air intakes under the van.

So does anyone have a pattern for the bottom tins? Even a rough shape will do? Do the tinware go between the exhaust pipes or under?

Cooling "fan" is actually a turbine, on the rear of the crank, hidden inside the large alloy (CU) or steel (CT) housing. You can't see all that much of it, if you look through the number plate flap, you're looking directly at it.

By "not get far", we mean that without it, your engine would run for a couple of minutes, tops.

Hello,

Under engine tin ware.

Firstly there are 4 pieces.

The first 2 pieces fit between the underside of the cylinder barrels and the pushrod tubes.

These are commonly known as 'cooltins'

It is perfectly correct to say that the engine should not be run without these.

You can only get them out when you do a full engine out, top end overhaul.

The second 2 pieces are the under engine guards, fulfilling 2 functions:

1 They complete the aircooling circuit tinware so that hot air is blown over the silencer, and out of the rear underside of the vehicle.
2 They protect the pushrod tubes from stones etc, and cold water splashes onto the hot cast iron cylinder barrels if you go through a big puddle.

Secondly:

You can make them very easily yourself:

DIY store: small sheet, about 1 ft square, of very thin aluminium.

A pair of stout kitchen scissors.

A cornflakes packet, preferably empty

A felt pen.

Lood at the underside of the engine and you will see 2 6 mm threaded holes in the bottom of the cranckase, also 2 or 3 tinware screws sticking out of the underside of the tinware at the front (front of vehicle end) of the engine.

Make template in card, copy to aluminium , drill holes, bend to fit, screw into place.

Et voila.


Incidentally, if you do ever find a pair, even in poor condition, mail them to me and then I could do a run of panel beaten ally replacements.

Cordialement,

Thanks for that info.

So basically you've got aluminium sheet above the pushrod tubes - "cooltins" and aluminium sheet below the pushrod tubes.

One more thing how far back does the 'under engine guards' aluminium sheet go? As close to the silencer as possible or should I leave a gap?

Sorry for being a bit of a muppet but I don't want to end up trapping hot air when there should be a gap for it to escape.

I don't suppose you have a picture of the underside as they say a picture is worth a thousand words.

Hello,

There will be a photo of the underside coming up shortly, (my master technician is fiddling with a card reader even as we speak)

Basically the lower tins dont go any further back than the rear, (rear of vehicle) of the cranckcase. You will (hopefully) find 6 mm threaded holes in lugs on the underside edges of the cranckase. Use these if you can.

The original VW plates were all in steel by the way.

Mr oorwullie in Switzerland has some in his 'Unobtanium ' museum.

At the time we looked at Bus Boys in the states for 2nd hand ones, worth a look,

Cordialement,

Tinware, photos are of a CT engine, but the tinware is similar.

Please excuse the state of the underside of my van. We dragged it out of the field it had been sitting in for over 5 years a few months ago and haven't touched the engine yet.

Front, looking rearwards.





Rear, looking forwards.





Those brackets are supposed to attach to the tinware.











Hard to get a shot of the cooltins without dismantling the engine, but this gives an idea of what they're like.

Many many thanks for those pics 82JEW75 ...that's a great help, as I now have some idea what to do.

Hello,

Don't laught at the state of the engine

Its muggins here who has to do the rebuild.

But I leave the cleaning and painting to the apprentice

Cordialement,

eeeugh steve, you've got a dirty bottom!!

French slang for peasant is "cul-terreux", literally, "muddy a***'d"
