Where is the thermostat located on a 1998 Honda Civic EX?

The thermostat should be located in a metal tube that runs behind the cylinder block. Follow the bottom radiator hose to the metal tube. It should be near the distributor, but lower and in the back more, but just follow the radiator tube and you'll find it. Drain your coolant and take off your radiator tube. Where the radiator tube connects to, look at it, it should have three to two small 10mm bolt that holds it on the metal tube. Take that it off and the thermostat should be in there....
