Hi, I just noticed that I don't have the part "101" listed on this image. It's completely missing from my car.

It's also not described on the page http://detali.ru/cat/oem_mb2.asp?TP=1&F=140134&M=603.971&GA=722.367&CT=M&cat=503&SID=20&SGR=015&SGN=01

Is it for some kind of balancing?

Never seen one. Have no idea what it is. What car is it on?

This will help. That is an epc exploded diagram, not everything there is on every car.

I think he's talking about the '92, he said he replaced the water pump.
