How to replace a thermostat in a cooling system on 2000-2011 Ford Ranger?

Before you assume the problem in your cooling system is the thermostat, check other things including checking the coolant level, drive belt tension, and temperature gauge operation. You must not run your vehicle without a thermostat so that your computer can work well and it will not have any negative effects on emissions or fuel economy. Disconnect the negative battery cable to replace the thermostat. Remove air cleaner air ducts and drain cooling systems. Look for an upper or lower radiator hose to locate thermostat housing. If there are any electrical connectors present disconnect them. In some engines, both housing and thermostat are serviced as one piece. Free hose from fitting, also cut off old or deteriorated ones when necessary and replace them with new hoses if possible.
