Coolant flow noise

[namrebo]

My 2021 2.0 you can hear the coolant flow, just periodically. I’ve always assumed it was due to thermostat opening or some valve opening allowing the flow to go elsewhere. I didn’t notice it before I had the water pump TSB done, however, my coolant temps always look normal and I always run good at 195 Deg F.

Anyone else have this? I’ll post a video next time I remember on a cold start.

Should have put in there, it only does it during a cold start.
Start, will run maybe 20-30seconds you’ll hear it. Then In another 20-30 seconds again,noise, RPM drops to normal idle. then again for the last time, the noise. Then it’s gone. Until the next cold start. Like I said, don’t seem to be an issue. Literally been doing it for awhile, like 5-7k I bet ya. New to the forum, just figured i would throw it out there
