Hi,

I have a 95 Integra (B18B engine). I notice that once I am cruising on freeway, the temperature gauge drops all the way, almost hitting 'C'. But when stoping at the traffic light for a little while, it rises back to normal. Would this be the problem on the thermostat? If yes, it is easy to replace it myself? Does anyone have similar problem? Normally, how long does the thermostat last?

Thanks
