ZZP Oversized Aluminum Radiator

The ZZP aluminum radiator is a factory replacement radiator made entirely of aluminum. It installs like a stock radiator with OEM style fan mounts and transmission cooler fittings.

This is the largest over sized radiator ever offered for the 3800.
the ZZP 97-03 Grand Prix radiator is 1.4" thick, and the 04+ Grand Prix core is 1.38", it's much larger than the factory 5/8" in the NA 3800, the 7/8" radiator in the L67 car, and even larger than our previous 1.25" thick ZZP over-sized radiator.

If you want to keep your 3800 cool, nothing compares to this latest offering.
With Full aluminum construction, it cleans up the engine bay with a strong appearance and durable construction.

Please check fan to radiator clearance. Leaks from physical damage or not checking clearance will not be covered under warranty.

Fits 97+ W-Body.
DOES NOT FIT GXP OR V8 MONTE/IMPALA.

Radiator petcock size is 1/4" NPT.
