Melted Water tank

...... place the fresh water tank close, like really close, to the rear silencer and then you'll have hot water available for a shower as soon as you arrive at your destination. Just a pity that they neglected to make the tank out of heat resistant material.
Has anybody else come across this issue? Should there be a heat shield around the silencer? There doesn't seem to be enough room. Everything looks straight underneath. Perhaps my vehicle has the wrong exhaust.
Any thoughts?

Thanks

I would have thought that the fresh water tank should be well away from the exhaust, what do you do about drinking water when its hot!!

Which side of the van does your exhaust pipe protrude from?

Frank

1995 Harmony had no heat shield, nor does the exhaust pass near the tank.

Frank may be onto it. Alternatively an exhaust from a Mk2 Boxer may have been fitted.

As Peter says, please provide photos.

If there's water in the tank it's unlikely to melt.

You can actually boil water in a paper bag over an open flame. True - try it an be amazed! 

Thanks everybody. The exhaust exits on the drivers side. It has 2 boxes - one in-line near the front and the second on the passenger side behind the water tank. I'll try taking some photos and posting them, but might have to wait until the w/e if I can't get a good image with the flash.
The hole is about half way up the tank. I agree it should be fine if the tank is nearly full, but if the engine is run with only a little water in the tank, then I guess there's just not enough contact to keep the tank wall cool.

Here are the photos:
Outside edge of the back box is actually digging into the tank

Exhaust system appears to have been installed in one piece all the way to the exit pipe from the catalytic converter (I presume that's what the small box is, closest to the engine).

Front box seriously misaligned to mounting, and attachment broken.

Is this the catalytic converter? So much space around it. Doesn't look right. Also shows another angle on front box mount.

Is this what it's supposed to look like?

Doesn't look right to me. I'll take some photos of mine tomorrow [if it isn't raining]

Frank

OK photos as promised. Bear in mind that mine is a Symphony, not a Harmony.

Back box mounting: I think yours has had some extensive modification?
Is the water tank on the Harmony in front of the exhaust box or behind it? its behind it on the Symphony.

Mine does have a heat shield

Looks like I need to get the Waxoyl gun out!

The tank is in front on the Harmony, and it wraps around the transverse chassis member.
The big difference is the location of the mounting bracket on the end of the back box. On yours it looks pretty central. Is that correct? That's what it looks like in the photo. On mine it is towards the back, so pushing the front of the box further forward into the side of the tank.

Thanks Frank, much appreciated!

Yes, the mounting bracket is central to the box. It looks like yours is not correct. I got mine on ebay for £40 from Clickcar parts in Nov 2015 and I was amazed at the quality of it for the price I paid. It was far better than one I had bought previously for £80+ . The Peugeot part number is CN381G BTW, same system for either petrol or diesel.

EDIT: that is for the system - not the bracket

Frank

The system on your Harmony clearly is incorrect. My money would be on an obstruction on the ground having hit the bracket on the end of the rear box whilst reversing, deforming it, nay folding it, towards the front of the van and towards the water tank. I suspect this has then caused the cat to slew to one side and become offset from its desired course. Also it looks like both coil springs which centralise the front end of the system are missing: I've got two spares in the garage somewhere but, as ever, might struggle to find them. Best to fit two new ones as I recall them losing their temper, presumably as a result of heat over time.

Unfortunately I can't compare it to my Harmony as I have a Mk2 system fitted but clearly your current system is not to standard.

Why would you want to drink WATER!!!

Why, what do you drink that doesn't contain water?

Frank

Thanks everybody. Definitely need to replace the missing springs - don't want to break the cat or the exhaust manifold by putting too much stress on them.
Frank, your systems certainly looks very good quality, including integral heat shield! I was thinking about having the misplaced bracket moved, but if I can get a system like yours for such little money there doesn't seem to be much point.

Thanks again everyone

Out of curiosity I poked my head under mine today.
Adjacent to the water tank, but nowhere near it, if you see what I mean, is the exhaust pipe that links the two silencers.
The actual exhaust boxes are completely out of the way.

Mine looks pretty much like the photos Frank posted.
It does seem that a 'cobbled' system has been fitted to yours.

BTW the front clamp on yours is fractured although there doesn't appear to be any exhaust leakage.

PB

Good spot, PB!

I've looked at the installation again in the light of everyone's comments. The cat is almost touching the inboard heat shield, and the front clamp is so far inboard that there's no way it could be secured to both sides of the mount.

I think I'll just replace it, rather than fiddle about trying to modify it.
