LS and LT Radiator with Fans for 1970-1981 Camaro and 1978-1988 G-Body Vehicles
For enthusiasts installing an LS and LT engine into a 1970 through 1981 Camaro or a 1978 through 1988 G Body with an automatic transmission this radiator addresses the combined heat output of both motor and torque converter in stop and go traffic and under performance driving. Its thick aluminum core and matched pair of electric fans pull air evenly across the face of the core at idle and under sustained load to help maintain target coolant temperatures. Precision TIG welding on both tanks and core provides durable leak resistance through repeated thermal cycles. Installation follows factory bracket locations for 4L60E and 4L80E applications so there is no need to modify supports or frame rails during fit up.
Aluminum Core Engineering for Efficient Heat Transfer
The radiator uses a premium aluminum core and tanks that balance structural strength with reduced mass to aid vehicle dynamics. Aluminum's superior thermal conductivity allows the engine coolant to release heat rapidly into the airflow, ensuring swift temperature drop even under heavy demand. Opting for a natural bare surface or a black epoxy layer adds a protective barrier against corrosion without compromising cooling speed. The lightweight assembly not only improves handling response but also resists warping and fatigue through repeated temperature swings.
Precision TIG Welds for Durable Leak Resistance
Each seam in the core and side tanks is crafted using precision TIG welding, resulting in consistent fusion with minimal filler material. This meticulous process forms smooth, stress free joints that eliminate potential leak sites, even under intense thermal expansion. Weld integrity holds up against the repeated heating and cooling cycles common in LS and LT engine operations, including the added load from an automatic transmission torque converter. Consistent weld quality translates into maintenance free performance and confidence on both street and track.
Integrated Dual Fan Design for Stable Coolant Temperatures
A matched pair of electric fans is preinstalled to draw air uniformly across the full surface of the core during idle, traffic, and spirited driving. By operating independently of engine speed, this fan arrangement activates precisely when heat rises, preventing hotspots and preserving optimal coolant levels. Carefully shaped shrouds guide airflow toward the core while dampening noise and vibration, delivering quiet yet powerful circulation. Combined with the core's capacity, the dual fan system ensures reliable thermal control under a wide range of driving scenarios.
Factory Style Fitment for Streamlined Installation
The radiator aligns precisely with original bracket locations for 4L60E and 4L80E automatic transmissions, requiring no modifications to mounts or frame rails. Coolant hoses follow the factory routing along the F Body chassis to preserve structural integrity and avoid cutting or welding tasks. This direct fit approach can cut installation time down to just a few hours, allowing builders to focus on tuning rather than fabrication. With broad compatibility across Camaro and G Body platforms, the design offers a true drop in solution for LS and LT conversions.
