Remember when you put them back on the torque is 10Nm or 7 ft/lbs

Do you know a torque spec for the Water Pump bolts as well? And how about the thermostat? I was guessing at them all.

Water Pump
Body - 10 Nm (7.4 ft-lbs, 89 in-lbs)
Pulley - 10 Nm (7 ft-lbs)

Thermostat
3 Identical Bolts - 9.9 Nm (7.3 ft-lbs)
Housing bolt right M8X30 - 24 Nm (17.7 ft-lbs)

Might be time for an electric fan conversion.

Plus one. Bookmarked. Even though I can usually find the particular torque values I need, having my motor's torque numbers in one place is great. Not too much different on the different chassis

You should be able to get those out with an ez out. You won't have to re tap the holes that way. Drill the center of the broken bolts, put the ez out in and turn to loosen. The tool is designed to run itself in tighter when you turn in the normal direction to loosen a bolt. I've had to use one several times. Most recently when one of the bolts for the rear diff snapped. By the way, don't lift the rear of your truck by jacking under the diff.

I think I would replace the water pump

:iagree:

I see this done regularly on all kinds of vehicles. Why not?

Because BMW says not to. And because I did (repeatedly) and I ended up with a broken bolt that holds the differential to the subframe, I suspect there's a reason they say not to.
