You may not believe this one! One of the top bolts on my water pump fell out on the road. As you can well imagine I had a pretty sever loss of coolant as a result, (the pump was fairly loose). I tightened the remaining nut on the stud but I need to replace the missing bolt.
Anyone know, or can find out, what size bolt this is? The stud nut has a 13 mm head on it.
Thanks
