I believe you can only get it at a Ford Dealer.. About 30.00 per bottle
And as far a antifreeze only use Motorcraft Premium Gold VC7-B or Zerex GO5 from Nappa

Buy 2 qts VC-9 (it is pricey).
Drain (you can omit the t-stat removal but it will be more time consuming if you don't).
Refill with 2 qts VC-9 and distilled water.
Drive for 1 hour with heater on (suffer is a location dependent activity...I expect PA is still HOT).
Proceed with subsequent flushes using distilled water until it looks the same coming out as it did going in.
(with a t-stat removal you don't have to drive to op temp...just hi-idle).
Refill after final flush using Premium Gold and distilled water in appropriate 50/50 mix (PG in first to ensure you get it right).

1. Drain coolant
2. Add 2 cans of VC-9 and top off with distilled water.
3. Drive 20 to 30 miles, preferably at highway speeds.
4. Drain radiator at petcock first, then pull lower hose. Then remove block plug on driver side. Not necesary to do passenger side.
5. Remove t-stat. To do this, remove air cleaner. Then 2 nuts on t-stat housing. Pry press. sensor bracket off of studs. Tight fit but it will move. Remove 2 more nuts and pull t-stat and housing from studs.
6. Remove t-stat and put housing back on. Re-assemble everything and fill with distilled water.
7. Run at 1200 rpm's for 3 to 5 minutes and drain as described in step 4.
8. Repeat 4 to 5 times or untill water coming at is as clear as water going in.
9. Install t-stat using new O ring. I used vaseline to hold the O ring in place.
10. After everything is re-assembled fill with a 50/50 mix of Ford premium gold or Zerex GO-5.
11. Start engine and check for leaks. This is a lot easier and quicker than it sounds. If you don't remove t-stat then you have to run truck between each flush till t-stat fully opens and then let cool down to work on it.
Highly recommend installing coolant filter kit while cooling syatem is empty. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

You can find the VC-9 on the net for $17 a bottle. We have a Motorcraft parts house in our town and everything is half the price of the dealership. VC-9 there is $17 a quart. Ive never seen this parts house advertise. The only way I knew about it was dad always buying from them since 1955.
