Buy a 110deg thermometer and stick it in the radiator. Cover the front of the rad & let the motor idle from cold to hot and check the gauge against the thermometer. At least you'll know what temp the gauge marks mean. Your sender may not be compatible with the gauge, or the gauge might be crook. I found the 4AGE gave incorrect (well, different to the 4K) readings on the KE70 dash, but now I know what temp the marks are at. A mate blew the head gasket in his Maxima because at boiling the gauge only read 'half'....
