does not have one. coolant is added through the recovery tank. if draining and refilling, just fill the recovery tank full of coolant. watch as you start car it may go down so add some more with car running. dont forget to bleed the system. turn heater and fan on full blast. locate the bleeder, it is on front on top v6. open bleeder till no air is coming out. then close it. you should now have good heat. good-day !
