Question 126 - Is there an auxiliary water pump?

103 engine manual shows an aux pump next to coolant expansion tank. The expansion tank shown in the manual is for a 124 car, so it appears that M103 equipped 124 cars have this aux pump.

My W126 has a 103 motor, but does not have the aux pump next to the coolant expansion tank as the 124 cars appear to.

Do the 88-91 300SELs(103 motor) have an aux pump and if so, where is it?
