Need some advise on coolant flow on a 250 Alloy Head Crossflow.
I have installed a Cain Inlet Manifold on a 250. This manifold does not have a coolant jacket so I have blocked off the fitting on the head that supplies coolant to the standard manifold. With the standard manifold this coolant exits the head via a hose to the inlet manifold, then exits rear of manifold and connects with a `T' piece to the heater return hose leading to the water pump. My workshop mannual states that this plumbing supplies the water pump with coolant when the thermostat is closed.
Will this cause any problems now that this is not connected, I assume this plumbing helps coolant flow before thermostat opens. Any advice would be greatly appreciated.
