How To Drain Oil Cooler

[RICK LAKE]

SuperHart B&G has a engine flush system that washes out all the oil in the motor and cooler lines. Dealerships have them. They work but I don't believe in washing a motor down with something that looks and smells like kerosene. The best way is to remove the lines and cooler and let the drain by hanging up. Run some brake kleen through the lines and cooler and let drain. Blow this out with LOW PRESSURE AIR. 20-40 psi. Reassemble and fill the system with new oil. I wouldn't worry about this UNLESS you have had a motor blowup and have metal in the oil pan. Add a magnetic half cup to the oil filter. This will catch alot of any metal particles. I would leave the rest alone. You have learn the line of letting sleeping dogs lay. Rick Lake

Rick, ya got me. What is a magnetic half cup, one of those magnetic whatchamacallits that clamps around the oil filter? Personally, I like the idea about breaking the AN lines at the sandwich adapter and blowing out the cooler with compressed air. I think maybe 100-150 lbs. of pressure oughtta do it (kidding).

I don't like the idea of running Brake Kleen through the oil cooler, though. If I needed to clean the unit that thoroughly I would just as soon remove the cooler and clean it on the bench.

Just about any marine supply store has the vacuum oil extractors, pull one of the lines and suck the oil out.

This thing also works great for lawn mower oil changes.

Yeah, I think that is what he means, I got one on my mustang.
I thought the only concern of this thread was to do a complete oil change and not leave a quart of contaminated oil in the system. I think all the flushes/brakeleen ideas are over the top anal, just break the lines, get the oil out, re-attach lines, fill...it's that easy!
