That is a lot of torque for 6mm (10mm head) bolts. I tend to question the torque specs in the Haynes manual. Some of them seem too high for small bolts being used on aluminum parts. I swear I can feel the bolt starting to yield when trying to achieve the published torque. For things like water pumps, oil pans, valve covers, and other non-life-threatening parts I use my calibrated fingers as the torque wrench. For head bolts, lower end stuff, and suspension parts I always use the published specs.
I would also recommend a light whisp of #2 Permatex on both gasket faces if you haven't already placed the pump. Those paper gaskets tend to work better like this. It fills in small imperfections or corrosion holes on the mating surfaces.
Hope this helps.
: I am replacing the water pump on my '73 tii. The Haynes manual says to torque the water pump securing bolts to 20 lb/ft. Is that 20 lb/ft for just the three 13mm bolts or is that include the four 10 mm bolts? That seems like a lot of torque for a 10mm bolt. Thought I would ask before a shear off a bolt.
: Thanks in advance.
