I've got an mx5000 that's about 10 years old. I want to drain the radiator. Where is the drain plug??
1st drain in 10 yrs?just detach lower radiator hose for the change. the radiator drain plug should be somewhere on the bottom of radiator, but would just drain via the lower hose itself. maybe a flush if it's been that long..... good luck.
