Quick question

in the middle of my cap and rotor swap right now and i have a quick question. Do i have to drain the coolant from the block before i pull the WP off? I already drained the radiator and all the hoses leading to the WP. Just dont want coolant spilling all over the opti. Thanks guys!

It will also ensure that your water pump gasket sealing surface stays dry. Just remember that after you bolt your water pump back on, connect all of the hoses. Unbolt the thermostat housing, remove the thermostat, and fill up from the water pump first. Once it's full, put the thermostat in, bolt down the thermostat housing, and fill at the radiator with the bleeder screws open. Once you see coolant coming out of the bleeders, close them.
Doing this will help ensure that you have no air in the system.

There should be a little locating dowel on the rotor, should only be able to go on the correct way. Be sure to use a dab of thread locker on the rotor screws.
