    Have a small coolant leak coming from the the water pump. Looks like its the seal between the pump and the motor. Is there a gasket that goes in there? or just an silicone type?
    also, 1.2m klm on the truck so if Im taking out the pump to fix the gasket anyway would it probably be worth replacing the pump as well?Would hate to have to do it twice.

    You might want to look at that real close and make sure it is not coming from the weep hole

    What is the weep hole? I can see it dripping from around the bottom bolt.

    The weep hole is a small hole in the bottom of the water pump. You have got to look closely to see if it is coming out of that hole . If it is coolant is probably is.

    And if it is coming out the weep hole, is that normal? Only seems to do it when cooled down and parked, and only occasionally. Not all the time.

    If it is coming out the weep hole that's your signal that the water pump is fixing to start pouring soon.
