Where do you add coolant to Mazda rx-8?

you add it in the expansion tank located at the front left when facing the opened hood - its the white / clear plastic tank with a metal cap on the top of it. only open the cap when the engine is cold or it will boil the coolant and cause it to spurt boiling coolant (water) all over you and you car's engine.

How do you get air out of rad on Isuzu trooper?

Add coolant to the coolant reservoir tank (a rubber tube runs from the top of the radiator to the coolant tank). The system is designed to automatically purge itself from air and replace it with coolant from the coolant tank. Watch the level of fluid in the tank and make sure you keep it filled to the "full" mark. If there is air in the system, you will notice the coolant level in the tank drop over time as the radiator draws in coolant and purges itself and the rest of the cooling system of air. Expect this to occur over several driving sessions. The cooling system is a sealed system; you can add coolant directly to the radiator when your vehicle is cold (if there is room), but NEVER when it is hot. It's best, however, to be patient by adding coolant to the reservoir tank and letting the system take care of itself.
