Remove any mounting brackets or bolts securing the radiator.
Disconnect the transmission cooler lines if applicable.
Carefully lift the radiator out of the engine bay.

4. Inspect and Repair

Examine the radiator for signs of damage or corrosion.
If a small leak is present, use a radiator sealant as a temporary fix.
For larger leaks or damage, replace the radiator with a new one.

5. Install the New or Repaired Radiator

Place the new or repaired radiator into position in the engine bay.
Reconnect the transmission cooler lines (if applicable).
Secure the radiator with mounting brackets and bolts.
Reattach the upper and lower radiator hoses, ensuring they are firmly clamped.
