Stupid question, but how do I bleed my coolant system?

 

there are two bleed screws which are loosened on top of the thermostat housing. you just need to undo them with a flat head a few to turns while the car is on until coolant starts to flow out. you might want to stuff a towel underneath to catch the overflow so it doesnt get into the opti.

 

Those bleeders do work but it is still a PAIN in the butt if you are refilling from a recent flush. Keep an eye on the temp gauge.
