OVERHEATING CAUSE DISCOVERED!!? (with pics)

After my recent overheating incident, I discovered a pinprick hole in the metal pipe between the rubber hose from under the driver seat and the top radiator hose. pics taken from underneath with plastic tray removed.
Drop of green coolant can be just seen.

Does anyone know if this pipe is available? Bongo bits don't list it.

Any repair tips, I would rather replace it just in case, but may use a temporary bodge.
Removing it doesn't look too hard.

What about chemical metal poultice and a steel band as a temp measure???

The only way to fix is a new pipe ..Bell hill garage (ad on this site) should have one. Very common failure.

If you paste this into your browser http://www.lushprojects.com/bongoparts/ ... 02).html#2
then is is the pipe we are looking at 15-19X?

If so then the stub pipe just by the leak appears to just be a drain pipe and could happily be removed, you could then saw out about 3 cm either side of the damaged section of pipe and replace with piece of rubber hose. Just check out the rest of the pipe to see if its about to form any pin pricks elsewhere.

Other than that it wouldn't take much effort to fabricate a new pipe, your local exhaust center could probably make one for you out of mild steel if you take the old one as a pattern. Make some new brackets to fasten it back onto the Bongo and clip them to the new pipe with jubilee clips if you don't have a welder.

Or pay a fortune for a new one.... :lol:

I wouldn't bother trying to repair the pipe.. It has rotted through from the inside and it will only go again very soon. Next time it could well be a bigger hole that drains your coolant and then !!!who knows what the result could be,

Thanks to everyone for their help.

It is indeed pipe 15-19X ( thanks sss)

( thanks sss)

Does anyone know the price of this part?

This looks like an ideal part to get made up in stainless.

Please keep the ideas coming.

Thanks again, I will let you know how I get on.

Cripes, looks like we'll be asking for batches of these to be made up in stainless, to go with our lovely new silicone hoses :roll:

Well spotted Adam - and Adams engine...I expect that's well spotted too 8)

Have already looked into having a batch made up in stainless. The cost would be very high unless a very large order was put in. The steel ones are reasonable and should outlive any Bongo they are fitted onto. Bell Hill have (or did) have them in stock and fit them for a pastime. It would seem to be a common failure on the older Bongos.
I will relook into stainless ones as I have just aquired a son in law who is a " metal frabricator"

As Haydn quite rightly points out, the inside of the pipe will be where the real horror story lies... Any repair at this stage would be VERY temporary unfortunately...

Looks a simple job in copper pipe if the diameters can be reconciled. What is the diameter of the hose (internal).

Be careful useing all sorts of different metals in the cooling system.
Electrolysis !! you might end up disolving your rad or something.
Anyone out there with knowledge on this subject.??
This is why the coolant alarm only uses 45 milliamps of current.

This is a P reg '97 in pretty good condition.
If mine has gone there could be many others nearly there!!!

Seriously though I don't wont to alarm anyone unduly, there are enough horror stories on here already, but this is hard to spot as all the coolant gets caught by the plastic tray so there is no obvious leakage.

thanks again for all the advise

Rads have been made of copper or alloy for the same cars depending where you shop for them.
