Oil cooler

Got this oil cooler, second hand from ebay. Seems to only have surface rust and at £5 + P&P was a lot cheaper than they sell in the shops!


As you can see in the picture above, I soaked internal chamber in white spirit for a couple of days. Then agitated it and found the left over rubber washer to the right of the holes.


When I took it apart, I placed newspaper in the corresponding holes on the engine block.
