Step 3: Using a 19mm socket and a large breaker bar break free the crankshaft
bolt. I have a manual transmission, so I just put the jeep in gear with the
parking brake on. It broke free rather easily.
Step 4: Drain the radiator.
Step 5: Remove the water pump, thermostat, and radiator hoses. Refer to the
water pump/thermostat replacement write-up.
Step 6: Remove the radiator by removing the 4 10mm bolts, 2 on each side. I found a deep well worked well, a regular socket with an extension would have worked as well.
Step 7: Using a 1/2 inch breaker bar insert the bar into the belt tensioner and remove the belt while levering the breaker bar to relieve tension.
