To help others help you, it looks like you have an 07 Magna (Correct that if I'm wrong
!).
On our 04 Allure, our Water Pump is in the water bay, behind an access panel. Ours was just replaced via this access panel. If needed, removal of some screws and careful sliding of a few electrical switches, allows removal of the full water bay large panel (Full access, vs mini access thru the smaller access panel
!).
They have screens on them, perhaps a good cleaning is needed of the screen?
And hope those with Magna's will update for your specific model, where it vary's from mine.
Best of luck to you,
