Coolant Flushing - Ford Dealer Service

Take a garden hose and rag to the upper hose and and flush it yourself. Watch the "purists" here cringe over that one....

I've never had a problem doing this. Flush it ever couple of years and you won't have a corrosion problem ever.

Mark opined in news: snipped-for-privacy@4ax.com:

What upper hose?

The radiator hose? What good would that do unless you took out the Thermostat first?

IMO, just drain all you can... fill with water, (distilled would be best)

Run warm for 20 or so minutes... drain again. Fill with 60/40 premix (again buy concentrate and use distilled) which would come out to about 50/50 with water remaining in.

If you have that "yellow" stuff in there... get it all out you can and use the green stuff.

Take off both heater hoses and backflush heater, before the final refill.

Yes, DIY was my first option, I have two gals of Ford Premium, but wow I have a dealer coupon (and time is short).

So if I HAVE to take it to the dealer... any opinions on their service offerings?

I've heard the stuff they use can actually CAUSE corrosion.

Thanks, Matt
