Keep a close eye on your gas gauge when driving without a thermostat, so you do not run out of gas. Your engine will use more fuel than normal.

Is it OK to run an engine without a thermostat?

A car without a thermostat would never even warm to operating temperature, much less overheat. The lack of a thermostat would create a constant flow of coolant through the engine, thus a constant cooling effect on the engine. … In this case though, the thermostat is not present, so this would not be a problem.

Is replacing a thermostat easy?

Upgrading to a thermostat that automatically changes the indoor temperature setting is fairly easy, and it can trim about $180 off your annual heating and cooling costs, according to the EPA. Simple models that only control heat are sold at home centers for around $25.
