Whats the best way to entirely flush the coolant system?
Do you drain it from the lowest point on the radiator?

The best way is to run around with WYNN's rad flush in for a few hundred miles first, it will push all the crap into the expansion tank, I normally get half a mug full, which all has to be cleaned out, this way the whole system is cleaned out properly.

The block should have a drain on it too.

good stuff is that wynns rad flush/holts speed flush,i used it when i was servicing my last car(rover 45ixs),kept it in for 48hrs and drained the system,flushed the rad out with a hose pipe at low pressure from the top with both rad hoses off then refilled with fresh water and ran the motor to get any muck out missed by the wynns/holts flush for 15 minutes and drained and refilled the system with fresh coolant.

however the speed flush did find a big leak in the water pump but im glad it did
