Re: Bleeding coolant (fe519)
Yes you need to do it.
Air in the cooling system reduces its efficiency.
There is a bleeder screw on top of the thermostat housing.
1. While the engine is cold, open the screw and coolant will flow out of the hole in the top of the screw.
2. When the coolant comes out in a steady geyser, close the screw. This should take a matter of seconds.
3. Top off the reservior.
