Chris,

The hot water is brought in throught he lower raditor hose and sent back to the engine by passing through the upper radiator hose. If I am remembering right, which I may not be, the coolant temp sensor is right there by the thermostate housing, and this would give a fairly accurate reading.

If I'm off on the schematic I'm seeing in my head, then of course you're right about blocking off the radiator.

This is just the way the shop I worked for at one time preferred to do it, and I got good results.

Thanks,

Josh <><
