Howdy Tino! (hey, lose the caps lock huh?)


You have the same engine I have probably. The failed impeller remnants will be congregating in your oil cooler. (that's where I found mine!!)

The oil cooler has 1/8-1/4" holes in it so not very much gets past it. Depending on where your power steering cooler(s) is(are) there might be some there too....but only if your raw water goes to the PS cooler prior to the oil cooler.


Cheers,


Rick
