Open drain, open cap on tank and plug on crossover and let drain.
Fill back thruogh crossover slowly.
After filling through crossover and starting and stopping the car sevsral times (Burping) when you can't get anymore in through crossover, top off tank.
Precautions, If your freindly to the enviroment, collect it and dispose properly.
Other than that, don't let anyone drink it.
You can refill through the radiator (expansion tank) opening. Fill to the cold level on the side of the tank. Then put the radiator cap on and finish the fill through the crossover tube plug opening. DO NOT OPEN THE RADIATOR CAP WITH THE CROSSOVER TUBE PLUG REMOVED OR THE COOLANT IN THE CROSSOVER TUBE WILL FLOW OUT AT THE RADIATOR CAP OPENING. Check coolant level at the crossover tube plug after normal driving and allowing the engine to cool to ambient temperature. Check coolant level in the expansion tank for proper level. Top up thru radiator cap if required.
yeah i filled thru the expansion tank, an left the coolant crossover tube opened too, big mistake,lol. I was nervous at first cause people say burping these cars are a pita. But i had no problems with it, car runs much cooler now.
Dont refill thru tank, go thru radiator let run and burp out then fill to proper level on tank. A good way to tell if you need to change your antifreeze if it has gone from that neon green to ethier a dark hunter green or starting to go darker into brown. Thats when it loses its power and will start to clog your radiator.
Precautions? keep kids away and especially animals like dogs, dogs love this stuff, only a tablespoon of this stuff will kill a good sized dog. (it taste sweet) takes i believe a cup to mess a human up bad.
