Coolant temperature sensor (ECT) and engine temperature sensor location

Well I'll send you a picture of the boxing. I don't know if that will help but there's numbers on it too. Since you say that it say It is a head cylinder temperature sensor. Can you send me the info on its location and if this is something requires to have this cooling system drained to replace I want to know so I can think about doing it now, so I'm and don't end up unit later. If I'm having overheating problems do you think it's a good idea for to change this it's same time? Also, I want to say I apologize I read my messages back the voice to text is not worth a darn sometimes I know I understand some of the messages might have been hard to understand. I wanted to apologize.

Okay, um. What I want to know is a is this a sensor that when replacing does cooling system in to be drained and I have a overheating problems then is it probably good idea that I change it?

Okay, I just in your last message I did not see that before I sent my last one. I guess that someone for my cooling fans then I guess it's my cooling fans are working then and this can go on him just keep it around if it ever goes out I have one to replace it. Thanks

Let me Try that message again. I guess if my cooling fans are working I can save it for another day.

How do I check it?

Okay, I think I'm getting a little confused just when I think I understand then I get unsure. So which on is bypass? Because I'm and had go ahead flushed with water before but my coolant back in.

I'm asking which hose is bypass hose to flush and fill entire cooling system?

You are incorrect in your answer because I have two upper hoses I have one lower hose. I have 4.6 engines v8 and 1998 Lincoln Continental. My lower radiator hose that go from my radiator to up to the housing of the thermostat housing and there is another hose that Connect to the top of that thermostat housing there to the engine block and then I have another hose to go from the and engine block into the radiator.

This is my problem: it's overheating because I did not completely fill up the system the 1st time because I only filled it through the overflow container. Now I need it fill it also through the hose to fill. Its a complete system but I need to a flush the system because it's got rusty from all this time I take it to work on it and I need to flush the rust out before a put my coolant back in. So can you instruct me on how to do that?
