Bleeding the air,out of,the coolant

Asked by Wirenutguy Mar 08, 2017 at 09:51 PM about the 2001 Volkswagen Cabrio 2 Dr GL Convertible

Question type: Maintenance & Repair

How do,you bleed the air out of the coolant hoses and radiator. I've installed a
new water pump timing belt all the hoses the radiator and the thermostat.
And it's still running a little over the half way mark on the temp hand. And the
heats not getting hot just a little warm

maybe the heater core is clogged . if there's two hoses going into the fire wall and if you can feel the both of them they should both be nice and warm with the heat on and at normal operating temp. if one is cooler the it may be plugged up . Just over half may be normal operating temp. Yes?

Air in the line can cause the same thing. Simply open the lid on the ball and it’ll burp out. Best to fill straight into upper radiator hose as well when refilling. If it’s not air in the line, check to make sure temp sensor is connected and wire isn’t bad.
