Will this bolt directly into my car without modifications?

Yes—it's designed to use factory mounting points and connection ports on the CT4 and CT5 platform. Install following your vehicle's service manual to verify torque specs and coolant capacity.

Does this come with hoses and clamps?

The assembly includes the radiator core and tanks. Hoses and clamps are not included—reuse your existing hoses or source replacements rated for your engine's coolant type and pressure.

What coolant should I use after installation?

Use the coolant type specified in your vehicle's owner's manual—typically a modern long-life formula for GM turbocharged engines. Flush the system per manufacturer guidance before refill.
