Does the car have to be at operating temps then bleed the screw on top?
Also do you fill the coolant up in the same spot as the radiator? By the windshield under the plastic covers-drivers side...

Thanks

If you are filling the supercharger and bleeding stock heat exchanger,
The fill tube is on the passenger side just below the wiper.

Manual states to remove cap and start engine. You should see the fluid go down after a few minutes. Add fluid.

When I was bleeding, I had someone watch the stock exchanger and when they saw fluid pop up from the bleeder, I stopped pouring and screwed the 3/8 cap back on. I then proceeded to add more fluid to the fill location just under the windshield drivers side until at proper level. Once proper, I put the fill cap on. Watch it over a few days and fill as needed.

Note. If you open when hot or bubbling, it may spew fluid or at a minimum rise up and spill, so do it very slowly.
