I finally got around to doing the fluid change thispast weekend. I couldn't find the napa fluid but went with the Royal Purple fluid. Bill instructions are very calculated and guides you thru word for word. I did have to go out and buy a 3/8 inch swivel but the rest was a piece of cake. I had just under 300 ml of fluid in my unit and did my best to angle the car to get everything out. With the car flat I pumped in 400 ml... One thing I did not expect was that the valve did not create a complete block for the cluid once the tube was removed. Fluid continued to leak out but very slowly. I just gave the car and extra pump of fluid. Took the elbow off with two turns and placed the drain plug in. Has anyone else experienced this? Just curios. I email Bill but have not heard back from him. But all in all I couldn't have done it without this kit!
