Had a look under my bonnet and noticed that the pipe that goes from the overflow spigot to the overflow tank has turned white!

If i rub it the white powder comes off.. Any ideas? Time to replace it ? Its not leaking and im not losing any coolant.

Nissan want $27 to replace it, which isn't too bad, its a long pipe.. None in stock, 7 days to get one from Japan.

Mate, if your getting a dry powdery residue coming off it, it is slowly breaking down, don't take any risks, replace it asap. I regularly check all these type of fittings and use things like armorall or such preservatives to give some feed into it. Is it still flexible or is it hardening up?

I had this happen and eventually it was leaking so I just replaced it with some fuel line we had laying around at work, works great.

Mine gets it to, I suspect detergent does it. It does not seem to cause damage.

Mine has been doing it since new. Bit weird, but it doesn't seem to affect anything and the hose feels ok. I suspect it might be the type of rubber used to manufacture the hose,

My pipe is also white, in regards to armorall, detailers will not touch the stuff, i used it on my new mondeo door trims, they started squeaking like they were dried out.

I use mothers plastic care. It looks like goof but does a better job than armour-ass

One question! Have you cleaned the engine bay with degreaser the white is a effect of the degreaser cleaner. Nothing wrong with hose. you can fix with some silicon spray but be careful not to spray every ware.

Seems I'm odd man out again, been using armorall on all my vehicles since it came out, this one for 10 years, everything is still OK, I don't put it on the steering wheel but most other things are fair game. Oh well! Must be something in the water.

Nah one glance at my engine bay tells a story of being driven off road a lot, and washed very little. THe last time i put a hose near it was when i came back from a beach trip, but that was just tap water.

Thanks for the feedback, ive ordered the pipe anyway, will fit it and keep the old one in my spares draw. Probably giving me a nudge to replace all my radiator pipes and keep the old ones as spares. Cheap insurance i guess

Knowing my adventures to supercrud i would get it a few cm short, or the wrong inside diameter and have to do it again.. Nissan one isnt too much more and its got all the bends and stuff in it, no biggie

Good idea, ill have a beer while doing it!
