I recently bought a 1992 Ford E-150 Conversion van. I replaced the serpentine belt and the air pump and gave it a tune-up. The van was overheating so I also replaced the thermostat, hoses, and radiator. Right after replacing the radiator, the temperature gauge on the instrument panel stopped working. I can't tell if the van is running hot and I am not sure why it stopped working? Can anyone help with my next move?

1992 Ford E-150 Question: Temperature gauge on instrument panel no longer works after replacing radiator?

Often after replacing the radiator the new radiator works so much more efficiently that the temperature gauge reads lower but it should read. Could the temperature gauge sender unit wire have got knocked off during radiator installation? The sensor has a red/white wire attached to it.
