1999 Civic DX Sedan (D16Y7)
It's getting unbearably hot now (Summer) My car has a rust/gunmetallish paint job I suppose, and a ridiculously dark tint so it doesn't help with the heat. I just took out my A/C idler pulley today, finally, and the whining is all gone and so has my Freon for a few months; I want to get the aircon running ASAP though, so here are some questions:

-Can I just buy the bearing itself and re-pack in the pulley?
-If I get a new pulley / new bearing, would the chance of my aircon not losing it's 'cool' be gone, or do I have to test for leaks? (assuming the bad bearing is the reason for loss of freon over time somehow)
-I'm ready if I can't get a bearing alone, to buy a DAYCO pulley on Rockauto for $30 shipped; anything better?
(Contacted NAPA today and it costs $50+ just for the pulley; i'd rather not buy that)


Here's a video of how it used to sound
(swapped cluster from an Auto '98 CRV and was testing the tach, whining can be heard)

Are you talking about the idler pulley or the compressor pulley?

Oops; didn't specify ... idler pulley.

Thread title edited.

Scout some local junk yards for a replacement idler pulley if money is the issue.

Thanks.
I actually did some more bit of research.... stupid of me to find this out now.
Size is (I hope): 70mm x 17mm x 20.5mm
Guess i'll just look out for that bearing new locally and pack the pulley; if not, junk yard.

Still wondering if the bearing affected my freon? Also; my car feels less held back now; there's a slight change in power unless it's just an audible illusion.

It's completely unrelated.

Give more details. How do you know the A/C system leak out all of the refrigerant?

I put refrigerant in one week; 2 weeks later it felt less cool; changed my headgasket and tried to increase work space by taking out the condenser. I ended up stupidly pulling off the lower hose and basically all of it emptied out.

Re-assemble the system with new O rings, replace the receiver dryer, and place the system under a deep vacuum and check whether the vacuum holds overnight. If not, pinpoint the leak by adding a can of refrigerant containing oil and a leak detecting dye. The leak is located where dye appears.
