LS Radiator with Fans for 1970-1981 Pontiac Firebird Auto Trans
If you are fitting an LS engine into a 1970 through 1981 Pontiac Firebird with automatic transmission, this dual fan radiator ensures coolant flow remains consistent under stop and go traffic or spirited track sessions. Boasting a fully TIG welded aluminum core and tanks, the assembly resists corrosion while shedding heat faster than stock units to maintain stable operating temperatures. Mounting tabs and hose connections align precisely with F Body frame rails so installation is a direct bolt in with no modifications required. Automatic fan control kicks in when coolant temperature rises, covering the core to prevent hotspots and deliver reliable protection for your LS powerplant.
Precision TIG Welded Aluminum Core for Enhanced Heat Rejection
The radiator core and tanks are joined by TIG welding with pinpoint accuracy, eliminating microscopic gaps that could evolve into coolant leaks under the intense heat of an LS engine. Uniform weld beads resist thermal fatigue during repeated temperature cycles, ensuring structural integrity over time. Aluminum's high thermal conductivity accelerates heat transfer out of the coolant, maintaining stable operating temperatures in both road and track use. Reduced mass compared to cast units also contributes to overall vehicle responsiveness and weight balance.
Optimized Dual Fan Cooling for Stop and Go Driving
Two powerful electric fans are preassembled and calibrated to engage automatically as coolant temperature climbs beyond preset thresholds. Their positioning covers the entire core surface, preventing local hotspots that can lead to boil over in congested traffic or spirited backroad runs. Low amperage draw preserves alternator capacity for ignition and lighting, while quiet operation keeps cabin noise levels down. This adaptive cooling system seamlessly shifts between city pace and highway speeds, protecting the LS powerplant under all conditions.
Durable Bare Aluminum and Black Epoxy Protection
Customers may select either the clean, natural look of bare aluminum or a robust black epoxy finish that seals micro pores against moisture and road chemicals. The epoxy coating adds a hard barrier that resists abrasion from debris, salt spray, and general wear, extending maintenance intervals. Even without coating, bare aluminum develops a stable oxide layer that slows corrosion without adding weight. Both options ensure the radiator core and tanks remain corrosion-resistant and structurally sound for years of service.
Direct Fit Integration with F-Body Firebird Chassis
This radiator is engineered specifically for Firebird models from 1970 through 1981 equipped with automatic transmission. Mounting tabs align precisely with original frame rails, delivering a no-modification bolt in installation that reuses factory hardware. Inlet and outlet fittings match standard LS plumbing, allowing seamless connection with existing hoses and clamps. By preserving OEM sheet metal interfaces and fan clearances, the assembly sits flush under the hood and provides a clean, professional appearance.
