heat exchanger

[jasnruby]

would a 1990 vw t25 1.9 petrol have a heat exchanger please
if so how much are they to buy please thinking of buying one , the mot advisory was a corroded heat exchanger and a poor exhaust and also surface corrosion on outer seal
any advice will be great

[kevtherev]

you don't need a cold start assist in our climate. (heat exchanger)
All stainless systems now do not have this vestige from the past.

if you remove the exhaust system and replace it with a stainless one (price is about the same) then it will never rust.
You can replace it with a similar system, they are available from Brickwerks, just Kampers and VW Heritage, to name a few.

Do NOT ask a Kwik fit monkey near it, they would not have the slightest idea how to replace it.
It must be done by a proper mechanic.

found this using the search

There are a few topics running on this subject so I thought I would put it all into one post that people can find in the future when they search for exhausts. I assume forum users do search first before asking?

These are for the most common watercooled 1.9 and 2.1 petrol engines and are not in any particular order

First of all you need to find out what exhaust system you have. Is it the early type or the late type? If your van was registered in 1985 don't go off your registration year as your van may have been built earlier than 1985.

The early exhaust was from 1980-1985 and the silencer is unsupported
The late exhaust was from 1985-1992 and the silencer is larger and supported by two saddles

The attached images at the bottom of this post show what the two types look like as you may have a post 1985 van where the tightwad previous owner fitted an pre-85 exhaust system.

Standard mild steel Exhaust

Standard mild steel Early and late exhaust systems available from

1) Justkampers - Exhaust system bundle packs available
2) German Swedish and French Car Parts (GSF)

Late DG/DJ Stainless Exhaust Systems

1) Brickwerks sell an exact stainless steel copy of the original late exhaust system.

2) Jp Exhausts sell as well as fit their own late exhaust version.



3) Turbo Thomas sell their version of the late exhaust system

4) It is also an option to fit the vwspeedshop early style exhaust system (see below for web details)

Early DG/DF Stainless Exhaust System solutions

1) VW Speedshop sell a stainless system that will fit both early and late vans.

2) Brickwerks are currently developing replica early stainless steel exhaust systems in consultation with their supplier.
UPDATE 11/07/2011: Brickwerks are currently testing prototype early system pipes http://brickwerks.wordpress.com/2011/07 ... e-exhaust/" onclick="window.open(this.href);return false;

When they become available it will most likely be posted on the Brickwerks facebook page

3) Consult your local Longlife Exhaust Centre to see if they will build you a custom exhaust

See an example here https://club8090.co.uk/forum/viewtopic.p ... 0#p7594110" onclick="window.open(this.href);return false;





4) Some members have reported that Turbothomas supply early stainless exhaust systems.

5) Fit the late style stainless exhaust to your early van.
The silencer needs supporting on the late system so the parts required are 2nd hand Engine Mount (025-199-221A) and longer M10x85 bolts, Silencer Saddles and straps . (Stainless from Brickwerks or 2nd hand VW originals)

If I have missed anything (most likely) let me know

your van will have the later type exhaust with the saddles I should imagine
but it would be good if you can confirm it
I have one on mine and do not have a heat exchanger... rusty or otherwise

[jasnruby]

confused now why would the mot advisory say the heat exchanger is corroded and insecure

[kevtherev]

Can you confirm your exhaust type?

[jasnruby]

sorry no . all I know is that its a 1990 vw t25 autohomes camper 1.9 petrol
would the vin n umber help?

[kevtherev]

confused now why would the mot advisory say the heat exchanger is corroded and insecure

It can be removed without issue.
it does not contain exhaust gas, it merely heats up the air inside it and allows the heated air into the airbox.

The MOT see a rusty, holed and loose exhaust component, they have to advise you about it.

thanks for your help
just one last thing its a vw t25 auto homes 88000 miles 1990 what sort of money should I
be paying for it , few seams have very small amount of rust forming

[kevtherev]

between 4 to 7000. IMHO
If it needs a new exhaust, factor in £500 and what it costs to fit it (which can be a nightmare of snapped studs in the wrong hands)
All the seams will be rusty inside, and it costs a lot of money to eradicate it properly.

Realistically it's an enthusiasts vehicle, old, quirky, with obsolete parts, expensive to run and maintain if your trotting off to a garage every month.
Self maintenance is desirable, with twice yearly services.

I love mine... it changed our lives in the best way forever.
Have you seen the buyers guide in the wiki?

[jasnruby]

no I haven't I could email you some pics for you opinion if you don't mind?

[kevtherev]

Sure..
