CHEVY WATER PUMP

2002 Chevrolet Cavalier

How can you tell if the water pump on a 2002 Chevy cavalier is circulating. I replaced the thermostat and it still gets hot and the hoses are cool. I loosened the plug to let the air out but nothing comes out. And hot steam comes out of the overflow tank.

That sounds like the seal is bad and the pressure cap needs to be replaced. It is not allowing the system to hold pressure in order to work.

Will when the cap is on steam comes out of the overflow line

Also the temp stays at around 195. I remember right before this started happening I had checked the fluid and I had a hard time getting the cap off the reserviour so it hadn't been checked in a long time. We just bought the car about a month ago so maybe the seal is bad on it after it being on there for a while but what would explain the steam coming out of the overflow?

Figured it out. Had a bad cap and I burped it correctly and now its running normally. I really do thank you for all your help.
