Hello Brains trust. thought i will chuck this one out there for clarity.
heater pluming, from aluminum manifold over the carbs that has the thermostat at the other end, thought a vacuum actuated valve, into heater core. out of heater core down in to metal pipe and forward and into the water pump. that is what it looks like to me after thinking and looking at the parts manual. can any one confirm.
the confusion comes about because i have a bypass vacuum valve fitted. unlike the manual. or is there a configuration i am missing??
