Anyone know how to bleed the system? does it have to be done after a coolant change? I have the maintenance manual and in the instructions on coolant change it makes no mention of bleeding.

Also cant find how to bleed in manual.

 

What I do is ensure the front of the vehicle is lifted (either on a sloped drive way, on ramps, jacked up etc...)

Open the rad cap, turn on car and set to full heat (highest heat possible...I'd turn off the A/C manually).

Let it run until the engine reaches operating temps, and the fan kicks in. If you don't see any bubbles from the top of the rad, stop the vehicle, top up coolant and close her up.
