• Coolant temperature instability during stop-and-go driving
• Transmission fluid heat management concerns in equipped vehicles
• Leaks or corrosion in an aging factory radiator
• Poor cooling performance from a damaged or clogged radiator assembly

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet placement, and transmission cooler connections before installation. Flush the cooling system, inspect hoses and clamps, and confirm the cooling fan, thermostat, and coolant condition are in good working order. Proper bleeding of the cooling system after installation helps prevent air pockets and temperature fluctuations.
