The FLUIDYNE PERFORMANCE Radiator Double 29x18 with Oil Filler Neck for GM applications is a high-capacity aluminum cooling solution engineered for vehicles requiring superior heat rejection and flow capacity. Designed with a dual-pass internal configuration, this radiator delivers efficient coolant circulation to maintain optimal engine temperatures during sustained driving, towing, or performance applications where OEM cooling capacity falls short.
The unit measures 25 inches in width and 34.5 inches in height, with a compact 7.5-inch depth that fits within standard engine bay dimensions on compatible GM platforms. Featuring passenger-side inlet and outlet ports, the radiator accommodates existing hose configurations without requiring complex rerouting. The integrated oil filler neck simplifies installation by consolidating cooling system connections at a single component, reducing potential leak points and improving underhood organization. Constructed from lightweight aluminum with natural finish, the radiator weighs 16.3 pounds and resists corrosion while maintaining excellent thermal conductivity for efficient heat transfer.
This radiator suits owners of fuel-injected and naturally aspirated GM engines experiencing cooling inadequacy—whether from increased horsepower modifications, extended towing loads, or operation in high-ambient conditions. The dual-pass design ensures consistent water flow distribution across the full core, preventing hot spots that compromise reliability. Restoration specialists and performance builders working with GM chassis appreciate FLUIDYNE's precision engineering and drop-in compatibility, eliminating the need for custom fabrication or adapter fittings.
The aluminum core and tank design provide longevity in demanding applications while the standard configuration works with existing thermostat housings and bypass circuits on GM vehicles. Whether upgrading for reliability, tackling hot-weather performance driving, or managing aftermarket engine modifications, this FLUIDYNE radiator addresses the core cooling requirement with straightforward installation and proven thermal performance.
