New AC/Delco RC-27 Radiator Cap is an upgrade over the GM OE Radiator Cap!
The AC/Delco RC-27 Radiator Cap ordered from E-Bay is an exact replacement for the original GM AC/Delco RC-27 factory radiator cap that came with my 1996 Buick Century Limited Naturally-Aspirated 3.1L 4-Door Sedan. The re-designed 15 lbs radiator cap has two small dog-ears on it for easy removal versus the OE AC/Delco RC-27 Radiator Cap which was completely round and a struggle to remove. Those under-the-hood rats reading this will appreciate GM upgrading the design of this cap for ease of use.
