Replacing Impeller - Getting ready for the Lake!

[TulsaTime]

Hello,
I need to replace the impeller this weekend but have a question.
Engine: 2006 Volvo 3.0L GLP-D with the impeller on the front of the engine.
It appears there are three bolts that hold the impeller housing onto the pulley.
Do I remove these three bolts to access the impeller or do I remove the pulley too?
Reason for asking, I can not find any information on "how to replace"
The parts link and diagrams here on iboats are usually pretty good about defining but I can't make heads or tails of those diagrams.
Also, what is up with that bracket that hooks up to the impeller housing?

Thanks in advance for your comments!

That would be called an OEM service manual. not a parts lookup. There are also 4 screws, not 3 holding the cover on.
Here is a link to the service manual, it may not say D on the cover, but it is the part number of the manual Volvo says to use.

Not sure I know how to answer that, or even what the question is ?????????????

Don is right, there are 4 screws. One is hidden behind the bracket. If it's the same as mine, then you will also have to remove the bracket. There are two 1/2" bolts holding it to the engine.

Thanks for the information.
The installation went well thanks to the service manual that Don S. graciously provided link information on.
I do have one more question. When I unbolted the impeller housing, I guess I failed to really look closely at the position of the attaching plate.
When I bolted it back on, it seems there is a sliver of a hole in the attaching plate on the top side. I didn't notice this when I removed the impeller housing.
Is this normal? I actually took it all apart again and tried to line up the 4 attaching bolts so the sliver of a hole was on the bottom, however, the bolt pattern would not allow me to rotate the attaching plate but one way....thus making it somewhat idiot proof.
Won't know if it's really idiot proof until I fire it up and run with the muffs on.
Thanks again for all the information.
