Heater Matrix Pipes?

[mollucy]

Hi,
Now are the long(rubber) smaller pipes that run the length of the van the heater matrix pipes?. One comes from the back of Engine block, The other near the header tank split from another.The one near the block keeps splitting. Time for new 2nd hand ones i think. Need to know that am looking for right ones . (1.6td jx).
Thanks in advance.

Why use second hand? - Mr. VW didn't when he built the van! False economy IMHO. Would you put second hand fuel lines on your van? Heater hose easy enough to obtain.

It's not very expensive to buy new heater coolant pipes, i was pricing it up here in finland and if i remember rightly it was under two quid a meter.
Not sure if that was top quality stuff with the language barrier etc.. but it looked and felt good.

If you can it would be better replaced with new stuff, you'll need no more than 6 or 7 meters or so i would imagine.

Aye, use new ones !

Aside = I have often wondered if, during very cold spells we get from time to time in the winter, if there would be any benefit from some sort of lagging on those pipes (esp the feed pipe) in making the heater hotter. Perhaps you Rob, in Finland might have a thought on this ?

Hello all, it would make sense to lag the feed pipe, as temperatures here plummet to minus 30 and sometimes minus 40!, I'm not too sure of the functionality of the heater in winter without lagging as i've had the van 18 months or so but only just now ready to register it for road use, the original engine failed massivley so had a donor engine completly rebuilt.

Just to add for interest all vehicles here have a heater element thats plumbed into the water jacket seals of the block, this is plugged in a couple of hours before your journey to heat things up before cranking, Finnish winter motoring takes some planning! Also got to allow time to allow scraping bullet hard ice off the windows before every journey.

Maybe the folks on here who are very considearte with thier engines especially in winter could use the heater element i mentioned? Just a thought. Or you could do what the Russian army do with thier UAZs and light a small fire under the sump

The compulsary winter tyres need to be payed for next *wallet runs away screaming*

I seem to recall the question of lagging came up a few year ago and the conclusion was it would make minimal difference. Something about them not being that exposed to passing air or something like that.

Yeh, I think it was likely me and I also seem to remember folks in general said "no benefit" for the reasons you mention.
