can you over fill your coolant?

[RON WOODGEARD]

Dubie,

I'm sure there are as many ways to clean or wash out a block as there is guys on this board..
One of my many step Dads worked as a Certified, Cadillac Mech. They would bring in a Caddy that had internal problems. ( not broken stuff of course) They would run diesel fuel, ( stove oil) Through the engine from top to bottom with the pan on and plug in place, run a gallon or so through it, let it set a couple of hours to break up any Gum ( albiet there shouldn't be any in a new engine) Drain this. Then changing the Oil Filter and replacing with new oil, AND 1 QT. of tranny fluid..(replacing one qt. of the oil) TRANNY FLUID IS A DETERGENT IE: A cleaner.. run the engine for ten minutes or so, then drain the oil again, change the filter and go.. to be safe I would change oil again in 100 or so miles (I would) You'll know when the water has been displaced, there will be No Foam... I have had engines with sticky valves and ran 1 qt. of tranny fluid in them running down the road and the cleansing properties of the tranny fluid will clean the sticky valve..(Also a Caddy Mech. trick)
Over the 35+ years I've been turning a wrench I have NEVER had problems doing this.
