Need some advise please. I am planning to do most maintenance on my own, but wonder about a couple of items. If I change the coolant, can I just drain the coolant, refill with distilled water, warm up engine, drain again and add proper coolant to achieve 50/50 mix? Will this do a good job without draining the block? I followed this practice on all of my other vehicles over the years, but maybe it is not the correct way.
Thanks for any help,
BD
