Ok,

So I am slowly getting my '71 240Z together. I bought it with the intake and carbs sitting in the hatch. I havent seen one of these cars together in person and I cant wait to get this running to drive it. I have a little question about the cooling circuit. On the drivers side there is a heater hose that splits into two parallel lines. One goes through the intake manifold and one kinda bypasses it. My question is, on the line the goes through the manifold, should there by some sort of a thermostat valve there? I dont think I want hot coolant going through there all the time. If there is a valve does anyone know the part number and where I could get one?

Thanks,

Adam

Originally there was a thermostat , 150 degree, that screwed into the outlet from the intake at the firewall end , then there is a length of hose connected to a tubing that wraps around the rear of the block to the passenger side . The water going through the intake will help with the cold blooded nature of the Z at start up and help to cool it from the heat of the exhaust manifold . I believe the thermostat is NLA . I run the water but without it . :rambo: Gary
