We replaced the radiator in our 1999 vw bug. Now I think there is air in the radiator.. How do I get the air out? Or could it be a bad water pump?

Answers from the Automotive Experts

Gail Dunn, Owner at Women's Automotive Connection Mary If there is air, it in is the line, not the radiator. You would have to flush the system to make sure the lines are clear. I am not sure why you think there is air in the system. If you had the replacement performed at a shop, take it back to them and have them check it. Unless the car is overheating, I doubt if there is a problem with the water pump. If there were, you would not get coolant to the engine and overheating would occur.

Gelina Aquilina, Service Advisor / Mechanic at You'd have to bleed the system. To check the water pump, the system needs a pressure check.

Maryann Croce, Owner at Croce’s Transmission Specialists Mary, On your 1999 VW Beetle. After a radiator is replaced there is a bleed procedure to remove any air. I would suggest having it bleed correctly first, before checking other components. Good luck.
