I followed my Bentley Manual VG92 for Draining and Filling Coolant. (*4:7*)
However, I first added coolant to the block via the radiator hose connection on the head.....just to be sure that there was fluid going through the water pump on start-up. Then I filled the expansion tank and followed the procedure in the manual.
How can I be sure that the system has the required amount of fluid? If I run the engine and make sure the fill bottle is full, will that mean that the engine has the requred amount of coolant??
What about trapped air? Does the system self-bleed??
