coolant reservoir, is this normal?

I was staring to clean the engine bay and just wipe here and there when I noticed that the coolant reservoir bottle was a little crusty. It's not wet or anything, just dry flaky stuff. Is that normal or does that mean it has a little leak and need to bring to the dealership? I am still under warranty.. Only 21k miles.

Thanks!!

 

Probably a small leak around the top return hose. Nothing too serious unless you're losing a lot.

 

I had the same thing so I put a small hose clamp around it and it stopped leaking.

 

^^^ This or do what I did and left it alone. Not a major or minor issue worth worrying about. As long as the engine isn't overheating I wouldn't worry about it, it is a reservoir.

 

My 2011 had it too. I wiped it clean and it has been fine. If it dos it again I will do the clamp.

 

thanks guys for the quick replies!!

yea not overheating or anything and haven't even filled it up. Not sure if they refilled it when i took it for the first couple free oil changes as part of their 10 point check or whatever they call it, but ill keep an eye now.

i think i did this with my other vehicle long time ago and i used zip tie around it and just tightened it enough

 

My 07 was doing this.. I wipe it clean and the next time I pull into the garage
And have a look it is leaking again. I fixed it with a plastic tie-wrap.. Won't cut into the hose like wire or clamp. Hasn't leaked for a couple years.
