    On the drivers side of the 6.2 by the oil filter you have 2 ports for the oil cooler, one feed and one return. I need to know which one is which?

    one way to find out..

    I dont know which is feed or return,but an easy way to find out would be to disconnect both,put them in a bucket,and crank it over for several seconds with the injector pump wire off so it wont start,and see which one squirts oil out of it..thats how I'd test them....:crazy:
