Where is a good location for my water temp sending unit to get the most accurate water temp reading.
Intake, water pump or thermostat housing ???

The head but you didn't list it,the water pump is the worst place.

I think the cyl. head is the best place if you cant do that go with the intake...towman

go with the intake because it gives you a true temp of the motor as the water exits

Hmmmm wonder why GM allways runs the sender in the head? Maybe all those over paid engineers should log on here....towman

Newer GM small blocks ('80's) had them in the thermostat housing. Anyway, we've never seen GM engineers do anything bass ackwards, have we?

I've always heard that the manifold was the most accurate. From the factory, the sending unit is just to tell you to shut the motor off. On our cars, its to tell you what's happening under the hood. The idiot lights just yells "THERE'S A PROBLEM, SHUT HER DOWN!", but a guage tells what's going on. That's why I think the manifold is better because its an average of the entire motor.
