if anyone can help please reply: Iam having an overheating problem on my 2000 ford focus ztec black top. While driving the temp goes all the way to the red area on the temp guage. I changed the thermostat housig but cant seem to find the coolant temp sensor. Others are saying this car dose not have a temp sensor,that it has a cylinder head sensor which is the same as the temp sensor. Does anyone know if this could be the problem and where this sensor could be located. I cant seem to solve this problem. I also check for proper circulation and it seems to be fine,added bran new coolant,maybe its the water pump,some oneplz help me. thanks neil.
