Hi,

My mechanic friend told me this; I am not sure this is a good way. I will put it before you guys to judge it.

Step 1: Put the heater control in the car to fully warm.
Step 2: Open the expansion tank cap.
Step 3: Disconnect upper and lower radiator hoses.
Step 4: Apply pressure in the Expansion tank mouth. (Optional!!; its going to take longer time otherwise)

He says this will drain all the coolant. Since there is a hole in the thermostat to assist bleeding.

What do you guys think?

Thanks
Arun
