My nearside heat exchanger has gone around the exhaust and is letting in smelly air with the heat on. Where are the best replacements sold? I doubt there are original but having some access to heat is a must in my bus.

Cheers,
Will

There is no explanation...

169 vs 109 for instance..


I'm more inclined to buy the more expensive one...

Yeah, lack of info is weird, especially when they (C&C) also sell the Danish version at £110. I'm assuming the expensive one is a German quality pattern part with more internal fins?

BTW, my heat exchanger had rusted through near the mount. It was quite simple to plug up with the welder - worth a go?

Which ever one’s you buy make sure you paint or powder coat them because they will rust quickly otherwise.
I bought the CSP HX and within a couple of months they were showing signs of surface rust. I mistakenly thought they were supplied painted but it is just a thin coat for shipping and doesn’t last five minutes.

Thanks everyone. I went against my gut and bought the 109 JK ones. Thinking so long as I baste them in exhaust paint. then they should last me long enough and provide enough heat for a little chill. The van is parked up all winter so it shouldn't see many really chilly days out.

Historically, there have been a LOT of problems with fit & finish of Danish manufactured "Danskpart" exhaust-system components, including heat exchangers; about which I wrote extensively during the late 1990s and/or early-2000s and had correspondence with the managing director of "Dankspart" in Denmark and the secretary general of the British trading standards organisation. There might still be problems, because the managing director of "Dankspart" denied any knowledge of any problems!

If you have ever wondered why, genuine VW exhaust heat exchangers, provide more heat to the heater & demister system, than pattern-part, exhaust heat exhangers, this cut-away cross-section of some specimens, featured in the following magazine article, should make the reasons more apparent:

Jim Tyler, "The Heat is On", VW Motoring, November 1998, pages 38~41.

The most commonly available pattern-part exhaust heat exchangers, seem to be those of the Dansk Autopart A/S brand, manufactured by J. P. Group, in Denmark. Other known manufacturers are Bosal Ltd. and Arvin Replacement Products Ltd., which both have divisions in Great Britain and possibly elsewhere.

Are replacement stainless steel sheet metal covers available for the OEM VW T2 exhaust system? Replacing the sheet metal would be the simplest solution.

On mine, it was the centre tube that rusted through which causes running problems and fume issues which are unsafe.

It's a steel pipe with an alloy heat exchanger onto it. What @Clem describes is indeed unsafe, very harmful even.

Yeah it’s a steel centre pipe. If it perforates the exhaust fumes get blown straight into the cab .
Mine went near the manifold joint so I was able to weld them up ok.
It’s actually mad that they rust through , it’s thick steel that gets red hot every time the engine is run.

I blasted mine, zinc painted them and then top coated them so I hope they’ll be ok now.

I wonder if Cerscote vapour blasting would be a more durable solution.
I used SMS Race Coatings based in North East England for my engine block which is being built by LVH Resto's.

I can vouch for that. Mine looked ok but were disconnected when I got my bus, I re-instated everything and nearly gassed myself just going down the road for some petrol.….internal tubes rotted out

After months of messing with my heat exchangers, and seeing the price of replacements I gave up and bought a diesel heater off eBay for £100, so happy I did, I'm toasty warm now !

I've been thinking the same thing. Is it standalone or similar to an Erbespatcher but a lot cheaper?
Where do you keep your diesel supply?

Pretty sure I’ve got an original pair in good condition in my workshop if you’re interested?

Similar to the Eber but yes, a lot cheaper ! It came with its own 5 litre diesel tank. I have all of it under the seat of the rock n roll bed. I'll take a picture later on if this rain ever stops and I can get out to the garage.
