Will this bolt straight into my truck without modifications?
Yes. This is the factory radiator — it mounts at the original points and connects to the stock coolant and transmission cooler lines. No drilling or adapter work required.
My truck has a manual transmission. Will this radiator still work?
This unit is engineered specifically for automatic transmission models. If your truck runs a manual, you'll need the manual trans version instead, as the cooling line configuration differs.
Do I need to flush my cooling system before installing this?
Flushing your system before installation is a good practice — it removes old debris and ensures clean coolant around the new radiator. Check your owner's manual for the correct coolant type and fill procedure.
