Also: Water pump / Timing cover bolts going into the water jacket, threads need to be sealed too.
Here we use the thread sealers called Aviation Sealer or High Tack. Dry out the block, apply thread sealant to bolt threads run them in and out a few times, and get the goo into the threads in the block. Then put a final application on the threads and install the bolts.
By doing it this way and with these products you can take the bolts out later on if you need to change a bracket or install a new water pump, and the bolts will still seal. Provided you drain the level of the water down below the bolt holes.
Lower Right 2 bolts, and Upper Bottom 2 bolts, go into water jacket and need to be sealed.
