If its burning it up and you keep having to add to it, Then you might want to get a intake manifold gasket kit they cost like 30 bucks, in the kit are two o-rings about a inch in size. they could be leaking and if so that water is being sucked into your engine and burning up in the chambers. This happened to me years ago. Hope its your problem as well for its a easy fix. look at your manual at the engine rebuild section. you can see them on the engine blow apart graph.

1) pressure test the cooling system to be sure there is no external leaks, some leaks burn off the coolant with no trace fairly rapidly so a pressure test is more definitive.

2) if the car is pushing coolant into the engine when the engine is off, the engine will start up very rough and run on one rotor until the fouled chamber clears out after about 30 seconds of run time.

3) make sure the overflow system is not restricted and sucking coolant in but not allowing the radiator to draw coolant back out. this is usually caused by a faulty radiator cap which commonly fail in RX7s as well as junk in the line from the radiator to the overflow bottle.


if everything checks out ok but the coolant is still disappearing, pressurize the cooling system to about 15psi on a cold engine, remove the EGI fuse and crank it over for about 2 seconds then remove both leading spark plugs(lowers) and check them for wetness, a bad water seal internally will show up as coolant on one or both of the spark plugs.
