? Do you have to back flush the s2k. Before changing radiator hoses? When flushing radiator?

Not sure what you mean. Why are you needing to change hoses so soon? Or the coolant for that matter. According to my Helm manual, the '01 coolant is good for 120,000 miles or 10 years. The '00 is the only model that needs early attention paid to the coolant.
Here's my coolant change "How To" thread in case it will answer some questions for you:

Xviper: I am not aware of any coolant that can last that long. I would not go more than 3 years - it is cheap insurance.

 

10 years !!!!!
I try for once every year or two....... if you *do* get rust, after 10 years, it's too late.......

 

I know what you guys mean about the 10 YEARS!!!! But, that's what the Helm manual states for '01's. This is one of the few things that the manual makes NO distinction between "normal" and "severe" schedules. After the first 10 years, they say every 5 years thereafter. They must really have confidence in their Type II fluid.
Go figure!

 

I am buying colored vanity hoses. Do I need to have a special pressurized radiator machine drain the fluid before change the hoses? Or can gravity do its job with out damaging the s2k cooling system.

 

(Do all this when engine is cold.) Clean off the rad drain plug area with a garden hose. Have a clean pan to collect the coolant. Open the rad drain plug and let it pour out. Remove the rad cap to allow for more efficient drainage. You can almost immediately begin with the top hose as the coolant will be gone from the upper areas of the system. By the time you are done changing that hose, the coolant should have stopped. Now you can do the bottom hose. You will still lose some fluid but not a lot. When you're done with the hoses, pour the coolant back into the radiator. There are two bleeder valves - one near the top front of the engine and one along the metal line that runs along the top of the firewall. Start with the first one by loosening it. Keep pouring coolant in till it comes out that bleeder, close it off. Top up the rad, put the cap on the rad, loosen the back bleeder (clamp and rubber plug). Start the car (with interior heater to HOT) and slowly remove the plug till fluid comes out. It may take a couple of driving cycles to burp all the air out. Just keep adding the fluid to the reservoir. It'll suck it in as it needs it.
