I killed my impeller when winterizing... how do I backflush to remove blades?

[tec10]

I started winterizing, but wasn't aware hose was kinked somewhere, so overheated really quickly. Impeller is in pieces. So now I need to backflush system to remove these- before I can replace impeller and start all over again. Can I do this (flush) by inserting a garden hose to the port side inlet to the thermostate housing, and watch for debris flowing out of lower hose removed from raw water pump? I think this would flush through oil cooler and power steering cooler... Would this work, is this enough?

I think that would work. I have done it using a couple of buckets of water to wash out hose backward.
