hi guys,just want to make sure,
16100-39506 is the the replacement water pump for the 08 ISF?

is this an easy replacement? im from the philippines,so my F was imported (no warranty from our dealer) i was thinking to let a local shop have them replace it, im just not sure if the replacement is a very difficult task or not, what are the things i should be worried about?

do we have an online repair manual?
TIA

Yes, that is the correct part number. I did mine a few months back and was surprised at how easy it is. Once you drain the coolant everything can be done from above and there is plenty of room.The only thing I would have done differently is change the drive belt at the same time. Also, you will need almost 8L of coolant.

Thanks for the reply,so we dont need to remove the radiator for easy access?
Is there anything i should look out for? Before removing? (Like for removing timing belts,you have to put everything at 0* before removing them,and vice versa when putting them back)

8L of coolant? The F uses concentrated coolant?(pink coolant) no need to add water?

No, no need to remove the radiator at all. Just drain the coolant from the radiator drain (you'll obviously have to remove the under cover, remove half the air box, the coolant reservoir, water pump pulley and then you can easily get to all the bolts on the WP. No need to ensure any of the pulleys are at top dead centre like when doing a timing belt. And if you can do a timing belt, this is going to be a cake walk.There's a thread on the forum somewhere that actually has a pdf of the WP removal and installation, I just can't seem to find it again, but I suggest looking for it because it gives you all the proper torque specs for the bolts. Also, removing the the water pump pulley can be slightly tricky, just because it turns.

There's some good info in that thread that should help
