2007 Miata overflowing but not overheating
Bought a 2007 Mazda Miata for my daughter in the spring. I noticed the overflow Reservoir boiling over, but not overheating. I read all the online threads that pointed to either the stat, the cab, or the entire Reservoir. I change Reservoir cap, and thermostat. Ultimately also changed the radiator. Still overflowing through the Overflow hose but not overheating. I understand the system is pressurized, so not sure what is left to swap out in order to get this thing to maintain coolant level.
