Tearing down my 04 xj8 4.2 no supercharger. To change water pump.auxuliary coolant flow pump has 1 bolt in.pictures in workshop manual. In this section show 2 bolts. Other pictures in another section show 1. So what's right 1 or 2. Thanks

 

Changed mine out 2 weeks ago and it only had one. It is possible to get your hand down to the pump and feel the bolt head(s).

 

Only one bolt.. there is a plastic pin built into the radiator assembly to guide the aux pump in place..

 

Thank u very much
