Product Details

This is a direct replacement radiator from CSF, designed to fit your 2014-2019 GMC Sierra 1500 with the 4.3L engine. It's built to match the original equipment manufacturer's specifications, meaning it has the same plastic tanks and aluminum core as the one that came from the factory. This ensures a straightforward installation and proper cooling performance for your truck.

CSF has been making cooling components for a long time, and this radiator is a well-built option for replacing a damaged or old unit. The plastic tanks are durable for everyday use, and the aluminum core is efficient at transferring heat away from your engine coolant. Because it's designed to be an OEM-style replacement, you can expect it to bolt into the factory mounting locations without needing any modifications, making the replacement process simpler.

When you're replacing your radiator, it's a good time to check your coolant hoses and thermostat to make sure they're in good condition as well. This CSF radiator is a solid choice to get your Sierra 1500 running cool again.
