Block Heater Location

Does anyone know the location of the frost plug on a 2016 3 Sport GT?

Did you find out? Temro says it's the same location as previous years. The Left Hand Rear of the engine.

Yep. Its located behind the exhaust manifold. You can see a brass plug with orange thread gasket sticking out. Never ever installing a block heater ever again.

It's underneath the exhaust manifold on the driver's side. PITA to get to :)
