LS Swap Radiator with Fans for 1970-1981 Pontiac Firebird Auto Trans
Swapping an LS engine into a Pontiac Firebird from 1970 through 1981 with an automatic transmission demands reliable coolant control and this radiator and fan package keeps temperatures in check on both road and track. Built from lightweight aluminum with TIG welded tanks and a core that resists corrosion the assembly channels heat away more effectively than stock radiators. Two electric fans are installed at the factory and activate automatically in slow traffic or under high load without any custom brackets or trimming.
Precision TIG Welded Aluminum for LS Cooling Reliability
The radiator core and tanks are joined by TIG welding, creating seamless joints that resist cracking and leakage under the higher thermal loads of an LS swap. Aluminum's low mass and rapid heat transfer properties help the engine shed excess heat more effectively than factory units. This fabrication method also minimizes stress concentrations along weld seams and delivers robust resistance to corrosion. Drivers benefit from consistent performance whether cruising city streets or pushing the powerplant on the track.
Dual Electric Fans for Consistent LS Engine Temperatures
Two high capacity electric fans arrive fully installed and calibrated to engage automatically when coolant demand rises in stop and go traffic or under heavy throttle. Their placement ensures uniform airflow across the entire core surface, preventing hot spots that can compromise engine health. Quiet operation and efficient power draw preserve electrical capacity for other LS swap components. Together they maintain steady coolant levels to protect your motor in all driving scenarios.
Bare Aluminum or Black Epoxy Finish for Corrosion Protection
Choose the natural aluminum look for a classic aesthetic or opt for the black epoxy coating to guard against road salt and moisture. Both finishes seal microscopic pores in the metal and block contaminants that can lead to oxidation and pitting. The epoxy alternative adds an extra barrier that resists chipping and abrasion in harsh environments. Each surface option extends the radiator's service life and keeps maintenance to a minimum.
Straightforward LS Swap Installation on 1970 1981 Firebird
This unit is designed to drop into Pontiac Firebirds from 1970 through 1981 with automatic transmissions, matching factory mounting points for a true bolt in application. No cutting, trimming, or custom brackets are required, and original hardware can be reused for a clean fit. Pre plumbed fan connectors and coolant hose locations align precisely with LS engine layouts, speeding up your swap project. Enjoy a hassle free installation and get back on the road with optimal cooling performance.
