also the engine block drain is on the right hand side of the block above the motor mount, thirteen millimeter and twelve inch extension with an elbow, and you will be able to crack it loose, make sure you do not lose the metal gasket, when you are ready to fill remove both vents, one on the radiator hose and one on the expansion tank. when fluid starts to run out of the hose vent close it and when the fluid runs out of the expansion tank close that and make sure you have heat.
p.s. make sure you use pentison blue coolant. have fun!
