Hope this helps
Let me know if you need to know what the numbers stand for
Thanks again Tyler,
Here is a supplementary question (correct me please if my assumptions are flawed).
Cold water enters the pump through hose 6, circulates through the block and comes out hot from the head's side port flowing in hose 5 towards the upper opening of the radiator.
Now on my rig I will have no heater and the oil cooler will be of the air type. What am I going to do with ports 9 and 7 on the water pump? Can I plug the expansion tank directly to the rad as I have seen on other cars?
Thanks.
Philippe.
