LS Cooling Radiator for 1973-1976 Chevy Corvette Y-Body
When fitting an LS series engine and automatic transmission in a 1973 to 1976 Corvette Y-Body, maintaining stable coolant temperatures is a top priority. The 1973-1976 Corvette Radiator 26" Wide Core (Auto Trans) with Fans provides a USA made welded aluminum core in bare or black epoxy coated finishes for corrosion resistance and efficient heat transfer. Its 26 inch core increases coolant volume and surface area, while dual performance fans engage automatically at low speeds to ensure airflow in stop-and-go traffic. LS inlet and outlet ports align with factory plumbing angles for direct installation without bracket changes or hose rerouting.
Optimized Cooling for 1973–1976 Corvette
This radiator has been engineered to replace the original unit in all 1973 through 1976 Corvette models equipped with an automatic transmission. The 26-inch wide core increases coolant volume and surface area, allowing the system to shed heat more efficiently under sustained load and stop-and-go traffic. Whether you are running road tours or track days, this upgrade helps maintain stable engine temperatures, reducing the risk of heat soak and preserving peak output throughout every mile.
LS Engine Integration with MuscleRods Mounts
Designed specifically for installations using LS powerplants, this radiator package works in concert with MuscleRods mounts to secure engine position and align drivetrain angles without guesswork. By matching the dimensions of the core and shroud assembly to the original radiator support, clearance issues around control arms and cooling ducts are eliminated. MuscleRods' precise mounting system ensures the radiator stays locked in place, preventing stress on hoses and fittings and maintaining factory-style belt drive geometry.
Premium Aluminum Construction
Every component of this radiator is crafted from high quality aluminum in the USA, combining low weight with robust durability. The thick aluminum walls resist corrosion and puncture, while internal cooling passages optimize flow distribution. The extruded side tanks and reinforced mounting ears offer strength at key stress points, simplifying installation and reducing the chance of vibration-induced fatigue over years of operation. This all-metal design guarantees consistent performance from the very first start to countless seasons on the road.
Dual Fans for Rapid Response
This package includes a pair of high-performance electric fans preinstalled on a custom shroud that bolts directly to the core. The dual fan layout boosts airflow at idle and during slow speeds when natural ram air is minimal. Each fan is wired through an adjustable temperature switch, activating only when extra cooling is required and shutting off to conserve power and reduce noise once the ideal coolant temperature is reached. The result is a precise thermal management system that adapts to every driving condition.
