Draining oil with an oil cooler fitted

[kenkelso]

I am about to change to fully synthetic oil, I have a Brickwerks front mounted oil cooler, what's the best way to get as much old oil out as possible?

Thinking of disconnecting fuel cutout and cranking engine with drain plug removed.

1.6jx turbo diesel.

Possibly a question for Simon

Well, you shouldn't really do that as it is considered bad to crank the engine dry. However, it practice, draining but then cranking for say 5 seconds isn't going to damage anything given that all the moving surfaces will still be a residual coating of lubricant on them (I can here a massive GASP!) up to you of course.

Just change as you normally would - you'll have some dirty oil in there no matter what you do, and it'll be very quickly diluted by the new. Next oil change will still have a bit of dirty anyway
