How to maintain best engine performance and prolong engine life

To maintain best engine performance and to prolong engine life
--Replace your engine water pump flexible impeller annually!

1.Use a non-petroleum based lubricant(silicon or soapy water) to help slide the impeller into the housing.
2.Install the impeller with a twistting motion onto the shaft(Never force an impeller onto the shaft)!
   The impeller must be able to move freely on the saft to properly prime and function
3.Use a small amount of non-petroleum based lubricant to help hold the O-ring when replacing the cover.

Congratulation!Everything is well done!
