the other day the thermostat housing froze and busted on my vehicle and i replaced the housing and the sensors now the heat gauge doesn't work when the vehicle is in operation but when you cut it off it shows the proper temp. note: it was working properly before the housing busted.

it sounds like the new sensor may be wrong.double check the part number and location for the temp sensor.

you may very well have a faulty cluster.that would require some very specific testing and equipment to determine.
