2002 Boxster S squeal

How does Minnesota not do auto inspection, did they become part of Canada?
Your car may not have any issue. An ODBII reader can tell you what monitors have completed.
I use a Bluetooth ODBII sender and Android apps to read those outputs
For the SAI monitor, it is set by a serious of drive cycles typically from Cold start to normal operating temps and other monitors having completed
The bummer for the rest of us in the US of A, it can be expensive and time consuming to get these monitors working, but they typically don't effect how the car runs, just handle emissions

My car doesn't seem to have an issue as far as the emissions are concerned. I don't have a check engine light on. In my opinion the fan motor does seem noisy but I don't have another car to compare it to. It could be normal but I think I'll try to lube the bearings just as a preventative maintenance thing.
I got my first oil change out of the way. I also plan to change the grease in the trans and flush the brake fluid. I'm busy at the moment doing a top end on my BMW R100/7.
Cheers. Ernie

Water pumps squeal before they go as well. I highly recommend giving that a check. Loosen the belt and see if the pulley has ANY play. play=replace. The M96 will do terrible expensive things if it gets too hot.

I pulled the secondary injection pump on Saturday. I bench tested it with a 12 volt battery and some test leads to listen to how loud it was. I removed the rear cover and cleaned the foam filter with some light air pressure. I'm sure higher pressure would blow it to pieces. I was able to part the two section by removing the spring clips. There are two stacked fan blades which come off pretty easy. That's where the fun ended. I was not able to take it apart any farther. I was hoping to get access to the shaft and bearings but it seems to be a sealed unit at that point. I put it back together and bench tested it again. it sounded much better. Maybe cleaning the restricted filter helped. I put it back it the car and will see how it sounds in the spring. If it still bugs me I'll pickup a new one or hunt down a used one. It's a pretty easy swap. It took longer to get to it than it would to do the R&R.

Thanks for the help guys.
