Hi guys

I've recently been given a 93 Ford Fiesta Cayman , its drinking lots of fuel and was told it could be the coolant temputure sensor..... how do I know if it's got one? And where is it located? Please

It's a 1.3 endura engine I think , I've already done a service a changed thermostat, so was gonna change temp sensor if it's got one?

Any help would be great
