Sup H-T. I got an 98 civic coupe with a jdm b16 in it and my problem is that my temp gauge has not moved in 2 days its been above the C under the line. Is my car really running that cold? I changed the sensors but did nothing. Before it use to take forever to warm up no it doesnt even move. I went on a 2hr drive and it didnt move a cm. Im thinking its the thermostat but it should of atleast warm up or move. I also have a fluidyne half size radiator. I can pop vtec and everthing when it says its running cold. Can someone plz help me out. Thanks

I would start with the thermostat.

Well my first question is do you have interior heat when you turn it on? If so then you might have a guage problem. The fact that your vtec works tells me that your engine is up to operating temp. If you have no heat then I would look at the Tstat being bad

Ok so i did the first test where i ground that wire and to see if my temp gets hot, but the needle didnt move. So that means my gauge is messed up right? and i look at the wire n seems fine.
