Re: Air Block in Coling System

I don't know about the vent screws - I've only ever had to remove the thermostat to radiator hose & bleed from there, but I'm attaching an exploded diagram which may help you locate the pump & throttle body.
Let me know if you need more detail & I'll see what I can find.

Re: Air Block in Coling System

Throttle body is around number 8 but you'll not be able to get to the water pump without removing the camcover.

To be honest you shouldn't have to do either....simply turn the heater to full hot, start the car and fill, squeezing hoses as you go. Get it to operating temperature and the fans should kick in. Keep an eye on the temp guage and make sure it doesn't go above about 95 degrees (fan at circa 92).

Check the level over the next few days as it may drop.
