The temp sensor is at the thermostat housing. I have been busy with work, but did make a fan shroud and seems to be much better air flow. While I was at it, checked the coolant flow. Moved well through the main rad when the thermostat opened. Still need to take it for a test drive.
There is a bypass hose.
The old rad was very thick, but couldn't see inside to count cores. It is a 3 ton truck.
Was going to reinstall the crank fan, but not enough room to remove the bolts with the rad in.
