A water running noise

[Dynamo]

Hi guys,

I just did the coolant flush/fill over the weekend and now hearing the same water noise. Would this product solve the problem?

thanks!

No need to buy anything. Here's how I got rid of the noise after a coolant swap:

1. When engine is cold, fill coolant overfill tank to "max" level.
2. Warm engine up and change the cabin temperature setting to cold, warm, hot (a couple of minutes on each temp setting) a couple of times.

Repeat until the coolant overfill tank level does not go down anymore when the engine cools off. Should only take 2 or 3 times. I did it over the course of 3 days where in the morning I would check the overfill tank level and add coolant as necessary and do the cabin temp settings while on the way to work. Then I'd repeat it the next day. No more running water noise.

Actually, I use this product on my all my cars. They are great for getting rid of the air bubbles and work quite well. You don't have to use this to get rid of the air. It'll eventually go away after awhile. You just have to monitor your reservoir. Just fill it to max until the level stabilizes.
