Changing Oil - How Do You Get The Oil Out Of The Cooler?

[mikel]

Hi guys,

I have a remote oil cooler mounted in front of the radiator. The oil filter is in the standard spot but with an adaptor. There are two braided lines coming from the adaptor that come up higher than the cooler then down to poke through near the radiator to the cooler.

Because the lines loop higher than the cooler, whatever oil is in the cooler doesn't drain when I do an oil change.

There is no drain plug on the cooler, but I could disconnect the lower braided hose where it connects to the cooler (and oil would spurt all over the place as there's no way to catch the oil).

Any ideas on the easiest way to flush this oil out of the system?

Assuming I can get the oil out of the cooler, will I have any issues with an air lock in the braided lines, given they're the highest point in the system?

Should I re-route the lower braided line so that the highest point in that line is the cooler?

Thanks

For the amount of oil held up in the cooler and lines it's not worth worrying about unless you have some seriously degraded oil you are trying to get rid of (naughty, naughty). If you need to get rid of it just drop a line off.

That's what others have said...

The oil gets changed every 5000km, but as soon as the fresh stuff goes in it's dirty on the dipstick after going around the block as it mixes with the grubby stuff in the cooler.

yeah we change it very regularly in the race car but never bother with the oil cooler....unless we've just blown up a motor of course
