Title: replacement for copper cooling lines
Post by: melinprov on July 18, 2020, 06:08:43 PM

anyone ever replace their copper water lines with braided steel or copper? ( Volvo Penta engines ) I have seen it done once but could not find out if it was successful---seems to me they used copper in the original engines to act as a extra cooling element -so rubber seems out of the question? Steel and copper braid look great but can cost a pretty penny. You can see these lines in this picture

Never had a Volvo apart, but I can't see the copper lines providing enough heat dissapation to be a concern.  How the lines are terminated might explain why they used copper, compression or flare?  Braided stainless would look nice, but honestly probably not worth the cost unless you are making the overall engine pretty as well.   I'd probably opt for function now and get that craft on the water.  Maybe repair the copper if damaged?    Now one thing to consider is that copper will shine up nicely, and stay that way with a clear coating.  Worked on many show car fuel systems that looked classy in bright copper.   Just some thoughts.

WOW -after I painted the engine black-including the exhaust and took the tape and paper off I used to cover the copper, I was really pleased. The copper and black look great together. I will polish it out a little and clear coat it!
