Be sure the cotter pin is freer to jiggle in the bell housing hole. =

Gently !! On these little bolts. As Paul said, over tightening these =

removing the pan, dimple the holes back the other way with ball-pein =
hammer to get the surface flat again.=20

Water pumps are cheap enough, but there are different pumps for =
different engines, fans and air pumps. =20

This is a safety feature that generally shorts out the distributor =
before engine overheats from lack of coolant. John Twist has a tip =
about setting the Bowden cable so that valve is just closed, not jammed =
closed, when the knob clicks off.=20
