I replaced the radiator because I was certain that the top seal was bad because that’s where the steam was coming from. Yesterday, I started the car and let it sit for about 20 minutes. I revved up the engine a few times and it was at normal operating temperature. No issues. I drove the car for about 30 minutes then stopped to check for leaks and it appears as if I still have the same problem but it’s not blowing steam at the radiator. Could the water pump be gradually going out? There isn’t any roaring noise coming from the engine. I’m stumped.

Hello,

The best way to check for leaks would be to pressurize the cooling system and then visually check where the coolant is leaking from.

How to pressurize the cooling system:
