Getting all the oil out of a 873 oil cooled duetz

[slewpumper]

Guys I have had this bobcat for about 5 years or more...it is a 1996. I run mobile synthetic oil in it. When I change the oil you only get about 10 quarts which leaves about 8 quarts in the cooler. I have been told this is fine but I would really prefer to get all the oil out. What do you guys do that own a oil cooled bobcat? Just replace half the oil that you can drain and call it good? I am wondering if I should try and push the rest of the oil out of the cooler with air pressure or maybe there is a drain plug for the cooler that I am not aware of. Give me some advice!...thanks!

I was thinking air pressure too, but the issue is, will the oil pump loose prime if you took all the oil out?
Hopefully someone that knows will give their advise.
