While I was recently winterizing my 2021 BT5210 I had noticed my water pump outlet hose resting on top of the metal wheel well cover. While the pump was running I could sense that hose pulsating and the noise amplified by the metal cover.
I placed a 14" length of split foam pipe insulation around the hose at the contact point.
Now much quieter to the point of almost not noticeable.
