Flushing Supercharger
 
I read the Techinfo on flushing the supercharger, but I just wanna recap to make sure I understand what I'm thinking here.

Tilt the car to flow the oil to the nose side and use large siringes to suck out the oil through a 1/4" hose. Then start the car up for a short period of time and continue pulling out the rest of the oil. Once empty put new oil in through the hose with other siringe and fill until oil is up to the cap threads.

Right?

Yep, thats how I do it.

I would not run the S/C unless it was full of oil. I don't believe the Techinfo is directing you to run the S/C when low on oil.

Oh yea, i missed that part. Dont run the car with no il in the sc. If you want to take of the sc belt you can rotate the SC by the pulley.

Turning the SC won't do any good. The way I wrote it is to drain it as well as you can, then refill it. LIGHTLY install the plug, and run it for about 5 minutes. Shut down, remove the plug, and quickly suck out the oil again before the particles have time to settle. Then fill it to the bottom of the threads and install the plug for the last time. The plug has an o-ring. No need to over-tighten, and don't forget that the nosedrive casing is aluminum ;)

Thats what I did about 50K miles ago. Time for another SC flush I think.

Dont run the engine with no or low SC oil.

Also, don't over-fill the SC, because if you do, the internal pressure in the nose might be higher than normal because of the reduced air space. This could cause it to leak.

I changed my SC oil per Will's instructions and it worked great. I didn't flush it, just changed it. Also, I measured the amount of oil I removed and only put that much back in. (It was up to the bottom of the threads)

good tip.

I just bought my 2 bottles of SC oil this morning - Time for the weekend flush out. Phew, that stuff stinks.... Did you know that oil has fatty acids and phosphoric acid in it? Not good stuff to touch or drink.... ;)

Cheers,
