What do I torque the water pump bolts to?
I searched, and found confusing stuff about 6+2, some other values, I'm confused.
What do I torque it to? In English? Version for dummies?
Thanks

the default when not specified is 6 plus 2 Nm or about 6 ft lbs for the 6 mm bolts , they really are not very tight . But when you have 13 bolts holding the pump to the engine they do not need to be very tight .

Test your torque wrench before tightening waterpump bolts. I had previously used mine to tighten the head bolts and although I changed the setting it decided not to click. Hence I overtightened all the waterpump bolts and then broke one of them. Luckily Jon928se came to the rescue again and managed to remove the broken bolt remains without using an extractor.
Now I test my torque wrench to make sure it clicks before tightening any critical bolts.

Sorry for the dumb question but, doesn't 6+2=8? Am I correct in assuming that 6 + 2 nm means 6.2? Or?

So, first torque to 4 ft/lbs, then to 6 ft/lbs

Interesting , the default spec for a 6mm bolt in Nm was 6 plus 2 for early cars , 6 plus 2 for 80-84 BUT the 85 >89 tech spec book (as Heinrich so gleefully pointed out 
) reads 8 plus 2 nm and 90 > is 8 plus 2 nm ........ to convert to Ft lbs multiply by .75 (close enough) . It probably makes sense , especially for older 928s , to use new bolts when you are going to properly torque them with a torque wrench because you never know how "experienced " they are .
