This is where I get confused:

 

said previously,

-ideal water temp =3D 160*~180*F

-ideal oil temp =3D 160*F

 

If we are cooling oil with water that is at best hotter than the ideal temp of = the oil, then are we not adding heat to it rather than removing it? =

 

If we are trying to cool oil, why would we feed the highest temp water to the oil/water cooler rather than the coolest temp water by tapping into the = pump housing where it enters the block?

 

Based on feedback, the water entering the block may be as low as 150*~160*F, = would this be cool enough to do an adequate job of cooling the = oil?

 

Also, which model of Mocal is being used?

 

...Chrissi
