Is there a way to completely flush the old coolant out of the block? I want to switch to a red high mileage formula and obviously I don't want to mix it with the green crap I have in there now. Thanks in advance!
You can buy the flush kits, hook it up to your garden hose and run water through the whole system. There are also 2 drain bolts on each side of hte block, in the middle just below heads you can take them out and you'll get pretty much all the coolant out you can, do that and flush it with water you should be good to go
