So just thinking through the process to drain, remove, reinstall and fill the cooling system in an 1969 SS 350 SB.
Have not done one in 25 years or so.
Remove radiator cap, open drain peacock, or for faster evacuation unhook lower radiator hose and collect fluid contents for local environmental collection
Disconnect upper hose, then lower if not done already.
Disconnect fan shroud from radiator while system is draining.
Disconnect and remove battery so you can get to the bolts.
Unbolt radiator left, right, top from support shroud.
Sent to local shop for restoration using original tanks and tag.
Bolt radiator to shroud.
re-attach fan shroud.
Attach lower hose.
Make sure drain peacock is closed.
Remove thermostat from block.
Slowly add antifreeze/water mix until it hits neck of thermostat housing.
Replace thermostat and attach upper radiator hose.
Check and tighten all bolts on shroud.
Install battery, and connect cables.
Start and run to temp watching the fluid level and add as air exits the system.
Adjust level when engine cold to mark on radiator.
check fluid every start for the next few until system stabilizes.
Have I missed anything?
Any better tricks to evacuate air from the block then removing the t-stat?
Someone told me to remove the the water pump belt from the pulley, then and run it around the outside of a drill chuck, pulling down tight to put tension on the belt and use the drill to run the pump a few minutes. Besides being a PITA to do, maybe easier with a smaller belt, I ask would a standard drill have enough RPM's to actually move enough fluid through the pump/jacket to evacuate the air?
Thanks in advance
