Thermostat Replacement: Dorman 902-812 or 902-5188 will both work or only 5188?

ok,my bad,but I don't know because you failed to state in your question if your engine is 1.6L Turbo or 1.6L Non Turbo.I don't see either one of those part numbers listed for your vehicle,although I do see part number 921-221 listed for the 1.6L Turbo N18 engine and a couple more from different manufactures like the one listed below. this is why I suggested to look at rockauto.com.
