LS Radiator with Dual Fans for 1970-1981 Pontiac Firebird
When installing an LS engine into a 1970-1981 Firebird with automatic transmission, controlling coolant heat is critical and this 1970-1981 Firebird Radiator (Auto Trans) with Fans meets that need with precise design and powerful airflow. It combines a TIG welded aluminum core and tanks that resist corrosion and seal out leaks while dual fans engage at preset temperatures to keep coolant moving even in heavy traffic or spirited driving. Mounting to F Body frame rails with factory brackets ensures a secure direct bolt in fit that aligns with original hose ports for a smooth installation process that maintains chassis integrity.
Precision TIG Welded Aluminum Construction
The radiator core and tanks are assembled with TIG welding to create seamless joints that keep coolant contained under high heat. This technique produces uniform weld beads that resist cracks and microscopic leaks, ensuring reliable performance when an LS engine is under load. Aluminum's excellent thermal conductivity speeds heat transfer out of the system, maintaining stable temperatures in both traffic and spirited driving. The careful welding process also contributes to structural integrity without adding extra weight, enhancing handling by reducing front end mass. As a result, the unit delivers lasting durability and confidence on every drive.
Adaptive Dual Fan Cooling System
Two powerful electric fans are mounted to match the size of the core and engage at preset coolant temperatures, preventing local hotspots. By drawing only the current needed, they balance strong airflow with minimal strain on your electrical system. This adaptive control maintains steady coolant circulation in slow moving traffic or during heavy throttle events on track. Quiet during highway cruising, the fans ramp up as demands rise, protecting the LS powerplant without requiring driver adjustments. The result is consistent heat rejection in varied driving conditions.
Coating Options for Corrosion Protection
Choose between the natural finish of bare aluminum or a durable black epoxy layer to guard against moisture and road chemicals. The bare surface develops a thin oxide film that inhibits corrosion while keeping weight to a minimum. The epoxy coat adds an extra barrier, resisting abrasion from debris and extending intervals between service checks. Both finishes preserve aluminum strength and contribute to fast heat rejection. This flexibility lets you match restoration color schemes or maintain a stealth look under the hood.
Direct Bolt in Fitment to Firebird F Body
Engineered for 1970-1981 Pontiac Firebird frames with automatic transmissions, this radiator installs using original brackets for a straightforward fit. Inlet and outlet ports align with standard LS hoses and clamps, eliminating the need for special adapters. It sits flush within the engine bay, preserving clearance for shrouds, wiring harnesses, and accessories. By reusing factory mounting points, installation time is reduced and chassis integrity remains intact. This design delivers a professional appearance and dependable cooling without modification headaches.
