    I unscrewed the plugs under each radiator. Loosened the bleeder screw near the top of the water pump. Put a hose in the reservoir & started flushing. I noticed the driver's side radiator flushing with lots of force. The passenger side had maybe a quarter of the force. Then I plugged the drivers side to see if I could create greater water pressure from the passenger's side and the water barely came out. Is this normal? Also I thought it was strange that the manual told me to run the air condition instead of the heater during the process

    I have a 348, and I noticed the same - the left rad dumped more and faster than the right rad.

    To do a thorough job you should remove the block plugs. Your thermostat stops a complete flush. There is a plug on each side. Be sure to use new radiator plugs and new copper washers on the block plugs.
