coolany system??

[thegosson]

On the coolant outlet from the block to the top of the rad there is a bleed screw. Open this when filling the system so any air will be pushed out. When the system is full, start the engine and slowly remove the bleed screw so any air left is pushed out by the pump pressure.

The rad top pipe isn't the highest point in the system so squeezing that won't remove all the trapped air.

hence jacking the front of the car in the air. i know someone who rung the threads where that bleed screw is, and so from then on iv tented to leave that lil fellow alone. to be sure to be sure........

Either the person you know or a previous owner must have somehow butchered the screw so, I've never seen one damaged before and they aren't easy to damage either.
