Coolant flush question

[truck7575]

I am going to perform guzzles coolant flush procedure and refill with delo ELC coolant. My question is, I want to go ahead and install a new water pump and 203 theromostat while I am at it. Should I install the pump then do the procedure or do the procedure then replace the pump right before the final Distilled water flushes and final fill? Any recommendations would be much appreciated.

Personally I would flush first then replace the parts... That way when you seal it all up you will know you are circulating clean fluids through the system... I just went through all of this and that is the way I did it. It worked for me.

So you would stop at the point where you are ready to start flushing with DI water change the pump then flush with the DI water and then add the coolant?

Yeah I flushed with chemicals then tap water then tore it down and the flushed with di'd water...

Flush, replace the pump, flush with distilled, replace the fluid.

Can anyone post a pic of where I have to open the coolant system up to COMPLETELY flush it. I have to flush mine there's oil in it after I replace the oil cooler.
