Radiator for Chevrolet Traverse (2009-2017) 3.6L

Direct-Fit Replacement Radiator for 2009-2017 Chevrolet Traverse (Lambda)

What it Does: The replacement radiator restores cooling capacity and heat rejection on the 2009-2017 Chevrolet Traverse to prevent severe overheating and protect internal engine components.

The Stock Chevrolet Traverse Thermal Fatigue

Factory radiators on the GM Lambda platform suffer chronic failure at the crimped seams connecting the aluminum core to the plastic end tanks. Over repeated thermal cycles, expansion-contraction stress degrades the rubber tank-to-core seals, causing coolant weeping along the side tanks. Furthermore, aged Dex-Cool coolant accelerates polymer brittleness on the upper inlet neck, leading to sudden cracks under standard 15-psi operating pressure. A loss of cooling system pressure creates hot-spot cavitation and warps the cylinder heads on the high-output LLT 3.6L V6 engine.

The Engineering Solution

This replacement unit is engineered to match factory downflow geometry while reinforcing high-stress failure points. It features an aerospace-grade aluminum brazed core with high-density, multi-louvered cooling fins designed to maximize laminar heat dissipation across demanding driving cycles. Heavy-duty composite nylon tanks are mechanically crimped with vulcanized gaskets for leak-free durability. The assembly incorporates an internal downflow transmission oil cooler designed for GM 6T75 automatic transaxles, preventing fluid heat soak. Each radiator undergoes pneumatic decay pressure testing to ensure flawless operation matching OEM part numbers 15950813 and 20759654.
