Can you run a 1996 Honda accord without a thermostat?

Answer 1

Can? Yes, but should you? No. The thermostat is an integral part of the cooling & emissions system. The thermostat allows the engine to reach optimum operating temperature very quickly which is a good thing. Without a thermostat the engine will take much too long to reach this temperature and in fact it may never reach it's correct operating temperature. Engines run poorly when cold. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions. The engine will get better mileage and last much longer. Install the correct thermostat and forget about leaving it out. There is no good reason to run an engine without a thermostat.
