Should I flush my coolant?

[Luke Duke]

The previous owner of my '03 Ex had it studded, EGR delete and a new oil cooler about 35K miles ago. It appears that he put Ford Gold back in. Currently, my ECT/EOT delta is great.

Should I run it as is until there is a problem?

OR should I replace the coolant with the good stuff? I would like to avoid the long flush process with Restore/Restore+ if possible, which I don't even think is necessary in my situation. Would this work:

Get engine up to temp so thermostat opens
Disconnect radiator inlet hose without burning myself
Dump distilled water into radiator until it runs clear out of the disconnected hose
Drain system
Refill with cat1 coolant

Get a coolant filter and change the gold crap every 50,000 and you should be good to go.
