Flushing external oil cooler

Getting ready to reinstall my new engine. The existing oil cooler has old dirty oil in it.
I'm thinking about using a drill pump to suck up fresh oil, and pump it through the oil cooler to flush out the old oil.
Do you think this will work?

Thanks

Dave

Sure, Why not? Give it a go!

Just be careful,
run the drill at a moderate speed,
and have lots of rags close at hand.

Don't try and rush the job by using comressed air even if you bend the air hose in your hand kinking it to reduce the air pressure,
I can tell you it's not a very pretty sight and a genuine frigg'in mess!

Alan, you read my mind!

Thanks for the tip.

Mission accomplished.

Went to West Marine and bought a lower unit quart pump, used to change the gear oil in outboard motors.
www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&langId=-1&catalogId=10001&productId=91936
The pump screws on to one quart bottles of oil, and hand pumps the oil through a 3/8" plastic tube.
Also bought a 3/8" barbed fuel hose adapter - this is attached to the plastic tube coming off the pump and bolts right up to the oil line going into the oil cooler.
My oil lines were not attached to the engine, so I could watch the progress - after pumping about 3/4 of a quart, the oil coming out of the line went from black to crystal clear.

The pump cost $10.99, and the barbed adapter was $1.68.

David,

If your "Old Engine" had Bearing or Mechanical Failure you are risking damaging your New Engine.

Many Engine Builders will discard any Oil Lines & Cooler that were on an engine that suffered mechanical failure.

You can't be sure you have got all the Metal Fragements from the Oil Lines or Oil Cooler. If any Metal Debris is left over they will effect the Bearing Surface's of your New Engine.(Grinding Compound)

What with the price of a New Engine; New Oil Cooler & Lines are a small price to pay for "Piece of Mind."

Good Luck with your New Engine.

Best to have it cleaned by a pro. Consider taking it to a radiator shop.

Or buy a new one...what's your engine worth?

Me, If I had a major engine problem. would toss it and replace the cooler with a new one , cheap insurance.

Use carb cleaner ,a hose and a funnel. Push it through with 10 # of compressed air.

Will be picking up a new cooler tomorrow - thanks for the advice.
