Honda CR-V pas pump very noisy when starting from cold, loud clicking noise,but quieter when warm also a grinding noise when engine turned off. The belt seems very tight, how much deflection should it have. Suggestions on cause and cure appreciated.


Try taking the belt off and checking the pump by hand, there will probably be a tensioner that you can check as well.

All components should be easy to rotate and not noisy or grinding.
