i was expecting a leak and the deposits be in one place...drying coolant leaving behind deposits.

but this is evenly spread over the tube. if i had to guess i'd say that the tubing is breaking down. i'd bring it to the attention of the dealer at the very least. tubing is cheap so they shouldn't mind replacing that under warranty. that and it's a 5 minute job.

 

Hello,


Same afternoon, went to the local dealer and showed it to technician. He told me it is normal and not to worry , how can it be normal? there must be some reason/s to happen such thing, right?

Any suggestion / comment will be appreciated.

Thanks,

Well since it's Halloween the tech's comment on that residue being "normal" reminds me of the dialogue in a fav movie of mine - Young Frankenstein.

Remember when the monster goes beserk and Gene Wilder asks Igor which brain he took - Abby Normal's brain,

Looks like residue from a coolant leak of some sort and not entirely normal.

Such a creature would have to have an enormous - well you fill in the blanks

Happy Halloween.

 

I think it's just the release agent from the mold when they form the hose. I see it all the time on radiator hoses. It's like a wax film.

 

+1 This.

And the Hyundai tech was right.

Take a damp rag and wipe it off. Let it dry. Wipe another rag sprayed with ArmorAll, 303 (the best stuff), or your favorite rubber protectant. Bet you never see it again.

 

White powder eh? lol

Thank you all for the comments and suggestions.

On this Saturday, I will wipe it clean and apply wax. Lets see what happens. I will keep you posted.

Thanks.

 

its normal. happens to many-many hoses when they go through hot/cold cycles. its also road grime drying up on your hoses from puddle splashes, salty rain, etc.

 

it's mostly minerals out of condensation from the hot and cold cycles.
