1998 502mpi. Disconnected feed to oil cooler and found zebra mussel remnants which I cleaned out. Question is are the cool fuel cooler and power steering coolers similar to the oil cooler in that they can catch debris? or are they straight through?

I think cool fuel is straight through design. Power steering cooler has the capillaries like oil cooler.

Thanks. I found some pics of oil cooler and realized that oil cooler is straight through. I'll check my power steering cooler this weekend.
