Step 1: Remove the 3 bracing bar running diagonally across your engine area.
These bolts are 13mm in size, so use the wrench or socket to remove them.
Step 2: Remove the coolant line.
Step 3: Using a pair of pliers, remove the two clamps that secure the upper radiator hose in place.
NOTE: While you are performing this task, it may be a good time to drain and replace the coolant in the vehicle. If you have recently done so, simply use a "catch pan" to capture the leaking coolant, and replace it once the task is finished.
Step 4: Remove the hose.
This may take a bit of pulling, as the hose is under immense pressure and heat throughout the daily use of the vehicle.
Step 5: Clean the connection ends with a dry towel and wire brush.
This helps to remove the particulates that accumulate over time.
Step 6: Using the pliers, put the two clamps on the hose itself, and move it into place.
Step 7: Once the hose is in place, you can use the pliers to secure the hose by moving the circular clamps onto the connection areas.
Step 8: Top off your coolant reservoir with anti-freeze, and replace the coolant line.
Step 9: Replace the bracing bar.
