Hello,
I am new to Rx-7s and have been working on getting the car registered and road worthy. Recently the add coolant light has come on the dash. I have the 50/50 mixture that is recommended to use but do not know where to actually put it. Does it go into the radiator or in a specific coolant tank in the car. I have included pictures of the engine bay. Any help would be greatly appreciated and very helpful.

 

Welcome ..

If you are just topping up the rad, then you can add your 50/50 mix directly into the rad through the radiator cap. You should also check your rad overflow bottle (not visible in your photos).

Just follow the black rubber hose from the rad cap to the Front Right Side (Passenger Side) of the vehicle and you should find the rad overflow bottle.

If you recently purchased your RX7 and haven't done much in the way of maintenance, you should start with a complete flush and rinse of the entire cooling system in your new RX7 (or any new to you car with unknown maintenance history).
