Yep, and coolant filter discharge to the right. If you can see the hole at the top right just inside the gasket groove that is the bypass output, Just below where the thermostat sits is the intake for the bypass this is why we MUST USE A LONG STEM THERMOSTAT. As the thermostat opens it has to shut the bypass intake or uncooled fluid will circulate to the block.
