I priced a water pump to heat exchanger hose for my D1-30B engine today.
At £98.30 is this value for money?.....I think not.

Is this the copper section ,I looked at mine and thought if that needs replacing would use 15mm copper pipe.?

It’s the flexible rubber one that connects the fresh water pump to the heat exchanger. Number 19 in this diagram.

Why do you need to replace it?

It has suffered a bit of chafe. I’m intending to wrap the affected part with self amalgamating tape, a ploy I’ve successfully used before.

Just cut the affected part out and replace with copper pipe secured with jubilee clips.

It's a piece of hose. Hyphose sell it by the yard or mile. It's no different just because your engine has a Volvo badge on it, it carries the same water as every other hose. Expect to pay about a tenner.

It’s moulded to fit in behind the alternator belt. The bends would be too tight to utilise a plain length of pipe. Inserting a copper section might be possible, but I reckon self amalgamating tape will suffice. It will always be prone to chafing over time though, so need to keep an eye on it.

They do silicone bends and elbows too. There's nothing you've got that they haven't seen.

I dont think self amalgamating tape would work for long as its under pressure and its a bodged job.

I could imagine getting creative with domestic plumbing for the curly bits - this sort of thing
and cheap and cheerful rubber for the straighter bits.
My Yorkshire wallet is having palpitations at the idea of spending the best part of £100 on a pipe, but you could easily spend most of that for a similar thing on a car, and they have 10 times the volume to absorb setup costs.

Depending on the diameter I would make a copper using solder fittings. It can be set up and marked prior to soldering and once painted will look far better than the original and last longer.

Thats a lot of work getting all the angles correct and buying all the fittings,on these engines the fan belt can catch the pipe so most of the pipe is ok,as I said just cut the damaged section out and replace with a solid section of pipe

I have greater faith in self amalgamating tape than you, and would always have some aboard. No use with diesel though. My hose isn't actually punctured, only scuffed, so I'll beef it up with SA tape and monitor.
Thanks all for your contributions.

If the hose has been chafed by the belt then the self-amalgamating tape will be chafed by the belt even more as it will stand proud of the existing hose won't it?
I had this problem with a Yanmar (previous owner had put the bracket holding the hose on wrongly), and lost most of the coolant in an awkward spot. Took a few days to get the part too, which was OK as the mess from that and the resulting exploding belt took a while to clean up.
It's definitely worth fixing properly.
