Replacing Fan M998

[missionexpert]

I'm hoping someone can give me some pointers here on replacing my fan. I had one blade break off recently and now I'm in the process of changing out the fan.

1. Can you replace the fan without having to take out the whole radiator stack?
2. If so, how can you get the hex bolt holes lined up in the fan clutch so access it?

I'm obviously already knee deep trying to take this thing off but can't see to find the hex bolts as shown in this picture...sorry I took this image from another member here, not my image! I expect that you have to remove the fan clutch to get it off and not just remove the nuts that hold the fan on.

I've already had the stack out of it back in September to change the water pump and I'd rather not have to go through that again. Any tips are appreciated.

You don’t need to remove the hex bolts. These are the nuts that hold on the fan

Thanks. I did undo the nuts on the fan but there was not enough clearance inside the fan shroud to push the fan forward enough and then on an angle to get it over the fitting of the fan clutch. In the end I removed the 4 - 8mm hex bolts by connecting my air compressor to the fan clutch line and put about 100psi to have it rotate freely.

Yup that's the best way. Hope it finished up well then?
