Could someone send me a link to a good how to for flushing the coolant on a third gen rx-7. I thought there was an engine coolant screw that i had to remove to drain it.

to drain *most* of the fluid, undo the drain plug on the rad, then after its empty there is a 12mm, or 14mm bolt on the center iron of the engine, just above the oil pan... undo that and get ready for a mess as the coolant hits the subframe and splashes all over..

recap

drain rad
on the CENTER iron, just above the oil pan on the spark plug side of the motor...

a small bolt.. undo that to drain nearly all the fluid out...


To flush... follow the above link


cheers

thank you so much guys. Does anyone have any feedback on before and after performance of the car.

 

Performance will remain the same. You will now experience the difference between fresh coolant and old and nasty coolant. +0 HP.
