If you use and older block, i.e. pre '02. You will have to drill a coolant bypass hole in the left (Drivers side) deck face of the block.

All MK8 blocks require the drilling of the bypass. Cast iron blocks do not require this since it was designed for a 2V. If you lay the blocks side by side you will see where the hole needs to go.
