 |
|
Okay ,before anyone tells me there are other threads on this subject. In fact I typed in "coolant pipes" and got 2297 hits on Samba. A bit over whelming but a comfort to know there are people whom care about these things.
Ok my coolant pipes are original,old and cracking length wise .no doubt about it being time to replace them, did I mention begining to drip? They did their service and its time to retire them.
The business question I have is after doing homework Stainless pipes are the overwhelming consensus. Ok I can see that ,but why have pipes at all?
I am boat guy by trade and running long lengths of heater hose is common in many yachts . Granted these are from the engine block to aux heaters,ect. and not engine to radiator. With modern higherend heater hose maxing out at 500 degrees Heat is not an issue. Is it fear of kinking or sagging, or? . It just seems it would be easier to run and alot less connections,hose clamps and probably less expensive.
Iam not trying to buck convention just wonder why pipes at all?

Much more vibration and chafe on a car than a boat
Add in ozone , heat, and road debris and it’s a different set of dangers to mitigate.

yeah but the 1.25 & 1.5 marine exhaust hose is some fairly awesome hosing.very durable out weave to it.
secure it nicely and protect from chafing where it passes sharp edges. with some edge trim (even VW used edge trim in some places) or thin plastic sheeting.
it'll be fine.

| Running the stainless kit from gowesty is not too bad and a worthy upgrade. Dropping the tank in order to run the lines/re installing the tank is much more of a pain than the rest. |

| I used marine coolant hose to connect to the belly radiators on the two bay window conversions I've done. Worked fine. |

While waiting on various suppliers, GW, VC, BD to have a SS replacement available I'm looking for some advise to slow/stem a drip leak at the join of the insert of the lower rad hose to the coolant return pipe.
My best layman hope is with a thorough wrap of HVAC duct sealing foil tape.
Any other experienced suggestions appreciated. |

No. Use the "Silicone Rescue Tape" and put Zip-ty's at each end of the tape so no accidentally unwinding. Works 100% better then other tapes and was made for leaks.
You can find it in Home Depot or Amazon

That’s funny & amazing😄
A parts van I bought from a handy man in a boating town used marine hose.
It seemed like really tough stuff. Maybe it was marine exhaust hose, it was really thick & heavy.
At the time I looked into the cost and it was quite high, but I could buy it locally so no shipping - which with the size and weight of the hose in that van would have been quite high.
BTW-here’s the search syntax to use to use in the future.
Maybe it will knock it down to 457 hits😄

Looks like it is the same tape. Just be sure to add the zit-ty at the end wrap. It holds really good, but the zip-ty is a safety backup for it.

i ran SS pipes in my build, but on the heater core lines and others, i opted in putting them all in a abrasion resistant sleeve. Id imagine this will work out in the end.
ran silicone through and through, but silicone isnt super resistant to wear

Various pipe kits exist and are a proven solution.
But I always encourage others to experiment on their vans

| Before the Silicone Rescue Tape I'm wondering what the community thinks about a liberal application of PVC glue first? |

If you check the little box for 'Title Only' it searches only the titles of threads for the query 'coolant pipes' and the result is reduced down to 139. Add the word 'hose' so that the the query is 'coolant pipes hose' and the results go down to 11 threads with this one matching yours very closely:
https://www.thesamba.com/vw/forum/viewtopic.php?t=644526&highlight=coolant+pipes+hose
Going to the sticky FAQ thread then to "Engine, Cooling, Fuel, Exhaust, Ignition, Electrical" and then to the cooling system section will lead you to the thread that djkeev linked. |

Probably kinda silent because members want to hear about the hose method and are avoiding blowing Vashon's post off-topic. 
Aging coolant pipes is a common, and serious problem, as such there are lots of threads. Perhaps too many?
If you look thru them you might find your answer and if you need to post there’s probably a thread titled well for your Qs.
I'm sure you will get lots of help!!👍🏽

Thanks for the heads up, didn't realize the drift until you mentioned it.
Just saw your 10 year update -most informative - and will do a more focused search. |
