Thread: Sealing Coolant Expansion Tank Line

Far safer to replace the pipe entirely as it is made of nylon and is prone to shattering. 8mm heater hose is available from reputable suppliers.

it is very vulnerable to human clumsiness just near the air box,,

Experienced that first hand also. Replaced with 8mm heater line aswell

Thanks for the replies, I had been thinking along those lines, but I was unsure as to whether normal hose would kink on the bends.

I replaced the whole line at 140k, genuine part, thirty plus dollars from FWD Yeerongpilly.
Its much softer, and used s/steel hose clamps on the ends.

Just replace the line with 8mm hose today....
After braking it yesterday.

Now there a thread about it.....

Yep, all of the above. I did the heater hose too, but as said before the genuine part is only thirty odd dollars so the cost difference is negligible. It only the brittleness after years of heat that causes the issue.
