Detailed Description

The OSC Premium New Automotive Condenser 3612 is built for vehicles that need an OE-style A/C condenser with the correct fit and thermal performance. Its parallel-flow aluminum core, extruded tubes, and brazed fin construction are engineered to move heat efficiently, helping the air conditioning system maintain proper refrigerant cooling. This condenser is a practical replacement choice for Chevrolet C10, C20, C30, K10, K20, K30, K5 Blazer, and GMC C1500, C2500, C3500, Jimmy, K1500, K2500, and K3500 applications from 1975-1980.

This part cross-references APDI 7013612 and Spectra Premium 7-3612 for the same application. The 3612 condenser is built around O-ring inlet and outlet connections and is engineered for multi-fit without changing the look or fit of the original system.

What This Part Helps Address

• Weak A/C cooling caused by a restricted or aging condenser
• Heat transfer loss from corroded or damaged condenser fins and tubes
• Refrigerant leakage at worn condenser connections
• Poor system performance after condenser impact or road damage
• Fitment issues when replacing an original-style condenser on classic GM trucks

Installation Notes and Tips

Verify core dimensions, inlet and outlet style, and mounting points before installation. This condenser uses O-ring fittings and does not include a drier or oil cooler. For best results, inspect the rest of the A/C system for contamination, leaks, and worn seals before charging the system.
