How do you bleed the coolant for a 1998 Mazda Millenia?

Answer 1

is this a 2.5 or a 2.3 supercharged engine. On most 2.5 there is a bleeder that is near the base of the thermostate housing. Similar for the 2.3. I am basing this that there werent many changes from the 96 model. before adding coolant , open the bleeder screw. it looks like that of a bleeder screw on brake calipers. Begin to fill the radiator/engine with coolant.you may hear an air fizzle noise that's the air escaping the engine as you put coolant in. No worries. When you start seeing coolant dribble a bit out of the bleeder screw close it and continue to fill the radiator until full. put on the radiator cap. Fill the coolant resevior jug about an inch past the full line. Start the car and run it to operating temperatures, ../until the radiator fans come on, monitor the coolant temp gauge inside the car. after this is done stop the car and let sit for 5to 10 minutes, If there is any air left it will escape to the coolant resevior jug and it will pull in what little needed coolant in in place of the air. Check the resevior level. if it has gone down a little no need to open the cap to check.

HUH???

did you make this up? the radiator for BOTH 2.5 and 2.3 is the same. the drain is on the passenger side, there is an access port in the lower splash shield, small hole about 15mm. using a Phillips with a large head, unscrew the drain plug. if you cannot find this drain, then you can remove the front splash shield, and then you will slap yourself in the head because now you can see it was there all the time, and you just spent a lot of time and effort that you didnt have to. if you drain it from the tstat hsg, you will leave a lot of coolant in there
