Check the water pump seal weep hole. The water pump seal design requires a coolant film for lubrication and cooling. Therefore, it is normal to observe a minor chemical buildup or streaking at the weep hole.

NOTE: A streak or chemical buildup at the weep hole is not justification for water pump replacement.

Use the following guidelines to determine if water pump replacement is necessary: Make sure the weep hole is open.

NOTE: A suitable tool can be used to remove any debris.

If no leakage is observed from the weep hole under operating conditions, do not replace the water pump.
