I had the new head tapped and drilled for a water temp sensor and installed it (Thanks Hobo!) The head gasket also seals the coolant passages between the cylinder block and head, there is not a whole lot of pressure in this area, but sometimes engine coolant can become corrosive due to the lack of service, and at this point, the coolant can eat away at the head gasket, and eventually it will cause a leak. If it does not come up at all, leaking valves or a blown head gasket is the problem. Re: 454 Chevy temp sensor 01/18/2016 12:50 AM In the first design of the 366-427 engine, all coolant monitoring was done by water temperature sensors installed in the intake manifold in the short water runners between the thermostat housing, and the front of the cylinder head.
