I have a V6 that I want to drain the coolant and replace with new coolant.I
looked under the radiator and did not find anything that looked like the
American type drain petcock.What I see is a red plug that has a cross that I
assume you can loosen with a large screw driver.Is that the point where you
drain the radiator?Please advise me or suggest.Thanks everyone!

And having drained and replaced the coolant, how does one go about
bleeding the air from the system?

It bleeds pretty easily. Fill the radiator with your 50-50 mix and start
the car. Wait for the fans to cycle on. Top off again and add to the
reservoir as necessary.

If your car begins to overheat, turn it off and let it cool. Add more
coolant as possible, and restart and wait yet again for the fans to cycle.

If you must add a lot more coolant, it's a good idea to let the fans cycle
again.
These problems almost never happen unless the water pump is removed.

Thanks. That's better than the Aerostar I just got rid of. For the Ford,
the way that you burp the system is to tilt the vehicle nose-upward. I
swear that I didn't make this up!

Unfortunately, I know you didn't make it up. My father owns an Aerostar.
