Guest Anonymous Posted February 24, 2002 Share Posted February 24, 2002 I was having trouble figuring out the intake heating system What does the hoses do???? check out my link. I have earlier carbs on my 73 ]http://home.attbi.com/~suntadz/engine_trouble.htm] let me know. Quote Link to comment Share on other sites More sharing options...
Bob_H Posted February 24, 2002 Share Posted February 24, 2002 The url is no good. The purpose of the intake heating hose is to warm the carbs/intake air and prevent carb icing/help emissions stuff. It will be no problem if you disconnect them. -Bob Quote Link to comment Share on other sites More sharing options...
RB30-ZED Posted February 24, 2002 Share Posted February 24, 2002 The water flow through the intake manifold is a very misunderstood subject. Firstly it provides the bypass system to ciurculat coolant through the block and head durring warm up. As the thermostat at the front of the cyclinder head is in the closed position the water pump draws water from the back of the inlet manifold through a small normally open thermostat ( most peaple dont even know its there ,just looks like a connecter for the hose )and also from the rear of the block at the heater hose outlet. This system firstly provides a even warm up of the block and head, preventing localised hot spots around the combustion chambers and exhaust ports, until the main thermostat starts to open. The second function is the small thermostst in the water outlet from the back of the manifold, as this is normally open, water can flow through the manifold warming it up as fast as possible the prevent fuel condencing in the cold manifold, allowing you to put the choke in faster and giving you a more constant idle temp. Now as the motor gets to operating temperature this secondary thermostat closes, as the block and manifold contain enough heat to stop fuel condencing in the manifold.

RB30-ZED Posted February 24, 2002 Share Posted February 24, 2002 Just got your URL to work ( you left the bracket on the end ), and had a look, on my Australian 73 i had one only hose from the thermostat housing to the front of the manifold, it then flows through the base of both manifolds and out through the small thermostat around the back of the head and joins in to the heater hose back to the inlet of the radiator bottom hose fitting on the timing case.
