Does anybody know what the capacity is for the cooling system. 2000 5.3........ It's suppose to be nice this weekend here in Oklahoma so I plan on doing a coolant flush and changing the thermostat and doing the coolant bypass all at the same time. And maybe even put on my TBS if it gets here on Sat. Should be a fun weekend!!

 

about 12 quarts total,but that would include draining the block...about 8 quarts in the rad and jug
