1992 Q45 waterpump replacement

Hi everyone, I am new to this group...I have a 1992 Q45. Been a great
car...the only major issue was the transmission. Replaced it with a
JDM...works fine now. My waterpump is leaking...not bad...but it will
only get worse from here.

How long of a job is it to replace this? Anyone have any feedback?

Replacing the water pump isn't too tedious, especially if you compare it to replacing 1 on a FWD Infiniti.

(Details c/o natsoundup on NICO)

1. Unbolt underbelly plastic pan

2. Take plastic radiator fan off.. (plastic screws)

3. Unbolt fan shrowd.. I think 4 bolts

4. Remove shrowd

5. Take off plastic cover in front of plenum (I think 3 bolts)

6. Take off 4 nuts from fan blade, remove blade.

7. Undo abuot 5 or 6 water pumps bolts

8. Loosen fan belt

9 Tap water pump with a rubber mallet or a 2 by 4. Water pump should dislodge.

10. Remove pump, scrape off old rtv.

11 New rtv on new water pump...

12 Start reversing.

13 Flush out radiator, etc.

It took me about an hour for everything,might take you a bit longer or a bit less.
