Hello dear friends,
New season new problems,
During on my V6 water pump replacement I’ve noticed bottom thread is connected to the water port but the upper one is not, something is broken or good to go??? Maybe during unscrewing that bolt something went broken?

Thanks

Maybe the casting is a bit different on your motor, I do not remember if my 4.3L engine was the same as yours.

On an unrelated note, I always thought the circulating pump bolts were kinda weird anyway, as they were asymmetric. However, compared to the Ford circulating pumps, the SBC circulating pumps were a breeze to change.


You will want to put some Permatex Aviation on the circulating pump bolts to seal them from water.
