My recently purchased 95 Civic 1.6L registers hot once the ignition is on and my fuel gauge registers full in a similar fashion...maybe it's just coincidence. After looking into it, I noticed the fan isn't kicking on as well. So I replaced the thermostat, ECT gauge sending unit (single wire) and the ECT switch (next to the thermostat) the only one I haven't replaced the ECT sensor (two wire). After installing the new parts I topped off the radiator and started the car. Once again the gauge shot up to hot. I decided to let the car idle with the cap off. I noticed the fluid was not circulating nor was it getting hot. After a 10+ minute span...the coolant was still cold to the touch. The car isn't loosing coolant nor is it overheating. Furthermore the car idles and runs smooth with no other problems.

Along with my temp reading hot and the fuel reading full; my check engine light turns on and off at erratic times and my speedometer does the same...it even does this weird bouncing thing where it goes from 0 mph to 100 mph and everything in between. The only thing that seems to work accurately is the tachometer. Could the cluster be doing all of this?

The temperature and fuel gauge could be due to a bad ground in meter cluster or a bad cluster ciruit board.

The CEL induicating could be due to a fault with the Vehicle Speed Sensor hence the erratic speedo reading.

First thing you need tyo do is to retrieve the trouble code ti understand if it is only the VSS that is at fault.
