Does the thermostat have to go in a certain direction to make it work correctly?




First, if your waterpump blew up, backflush each part of the system. Pieces of the old impeller can clog the water passages.

Second, the wax pellet end of the thermostat must be upstream so that it senses the heat of the engine. This end is usually flat. The bleed hole should be at the highest point.
