OSC

OSC is listed for radiators, condensers, and heater cores — three heat exchangers that get lumped together as “the radiator” when they are not. A heater core that steams the windshield is not a condenser that sits in front of the A/C radiator.

GPD is the A/C brand also on our list. Tell us which unit leaked. Call (408) 327-1000. The San Jose counter will look it up before you drive over from Sunnyvale or Fremont.
