350 block flush help...

[78C10BigTen]

So ive seen it done very briefly but not sure how to do it. Can anyone tell me or direct me to where i can find out how to flush my engine with a garden hose? If its even possible without flushing the radiator and heater core. Im looking for a low cost way to flush my engine and replace my coolant and maybe gain heat for winter. Sorry if this thread sounds very amateur and pointless...

You could get the Prestone Flush Kit. It flushes the whole system though.

X2 Prestone kit. Walmart TLE has them on the shelf. All the instructions are on the package, but you just tee it in to your heater outlet (I think) hose, and it comes with a garden hose adapter and a spout to stick in the radiator so it doesn’t burble out everywhere. I recommend using a small piece of hose at the end of the spout if you don’t want water, muck and coolant gushing everywhere.
