Gromit Posted May 25, 2008 Share Posted May 25, 2008 Am installing a heat exchanger for my veg oil conversion. Which way does the coolant flow through the metal pipe along the side of the cylinder head? I take it that this is the return, so it flows forward from the heater to the thermostat. Is this correct?
