Oil Cooler: cleaning the oil cooler

The above photos are of the 'doghouse' type 1 oil cooler from the engine.

After unbolting it, I noticed that it has bits of rust inside it. Whenever I shook it, particles of rust kept falling out of the holes like pepper.

I repeatedly tried to shake out all the dust but that prooved futile so i poured vegetable oil (didnt have any motor oil) and let it stand in it overnight and then drained the oil out the next day.

I repeated this about 3 times and the rust soon dissapeared.

The next thing to do was clean off the paint.

I purchased a tub oil paint remover and gently applied it on until most of the paint literally dissolved off. After i did this, I gave the oil cooler a good clean with sand paper, and a wire brush. The wire brush proved to be most effective.

After most if the paint was off, particles were still trapped between the vanes of the cooler so I gave it a good clean with an air hose from an air compressor. I also sparayed pressurized air into the holes of the oil and this removed tiny particles trapped inside and ensured me that the oil cooler was not punctured/damaged in any way.

The last thing I did was heat briefly with a gas torch to remove any final particles and to ensure the thing was clean.

The above photos show the oil cooler after it has had a good clean. Next thing I'm gonna do is spray in blue, it's ready for use now :)

Next post is about the cleaning/removing of piant of the ignition coil.
