Kreon

[Viper5]

I was told my car needs Kreon??? Apparently there is a whining sound within the first few seconds of startup (like 20 seconds) and the people at the dealership said I need to refill the kreon. The sound isn't always present. Also, I am receiving cold/hot air when I need it so my a/c seems to be working fine. I didn't even know cars used that element. How the heck am I supposed to do this?

EDIT: I think I may have meant Freon.

The refrigerant R-134a, often mistakenly referred to as Freon (which is the Brand name for Dupont R-12) also contains the lubricating oil (usually a PAG oil such as PAG 46) to lube the system's internals and compressor. If you have a refrigerant leak, from pinholes in the condenser or at the 'o' rings, you also lose the oil with it.

But, I'd be surprised if this is the culprit, though it may well be. Before making the diagnosis that it's the refrigerant oil, I'd want to rule out the bearings on the idler pulley, alternator and the compressor. Especially if you've not noticed any drop in efficiency of the AC, this is the more likely source(s) of your whine.

Cheers!

20 sec whining at start-up. Are you hearing the air pump for the emissions... maybe? Its rather noticeable in mine.

Actually, I believe you have a Klingon caught in your serpentine belt!
Kreon is the only known element that will cause alien beings to release their deathlike grip on mechanical objects. It is the element Ripley sprayed on the alien in her escape pod to get it to come out and be blasted into space.

I think Quickurts theory seems the most plausible. Now where to get some Ripley...

I don't think it's the air pump since it only happens sometimes and it's definitely a whining sound. The people at the dealership heard it and the first thing they thought was the Freon.

Even if it's only for a few seconds on startup? I thought if the bearings were worn, then that sound would eminate throughout the drive.

Just your DVD drive starting up...

But that goes double for ANY component lacking lubrication. It is not going to get better, the longer it runs. If it is low on oil in the AC system, I don't see it quieting down after 20 seconds. That sounds more to me like something getting pressure engine oil, but even then 20 seconds is a long time for oil to "reach" it.
They have so many different types of pre-lubed, sealed bearings in different components, it's hard to say.
