Location of coolant sensor 2000 ford tarus station wagon 3.0 liter v-6

Not sure I follow you.
The engine temp sensor sends a signal to the engine computer and the computer decides when to activate the fan relays. So if you have power to the fans you would also have power to the high or low speed relay the temp sensor is probably working. There is a third relay for the ground circuit.

I have a Mercedes Benz s430 2004. I have replaced the radiator fan 2x so far and its broken and not working again. All of my spark fuses are good since I just had a tune-up. What could be the underlying...

Check cooling fan relay. Check your owners manual for location and discription. This might have been you problem to start with or when your first fan failed it may have damaged the relay. If you dont have an Obd II scanner. Try resetting your cars computer by removing negative battery terminal for 60 secs. then replace terminal. See if this works for you. Try to reset computer first then check relay. Good luck. Battery may be in the trunk.

We have benz s500 2006. looking for coolan fan relay .how we do fit coolant fan relay.and where it is lookated in fuse box.

First of all, I don't mean to be a pain, but why are you wanting to "fit" the relay? If you don't know where it is, you could not possibly have tested it. If you have not tested it, then you cannot know with any certainty that replacing the relay will fix whatever problem you are trying to repair. There are a lot of other possible causes if you are trying to fix a cooling fan that won't work.

Please take a few moments to read this article: What Else Could Be Wrong?

With all that said, The relay that controlls your fan motor is the "Circuit 15 Relay". It is located in the Driver's Side SAM Module. It is marked "N" in the picture below.

I have a 1994 s320 after switching of the engine the two similer looking fans in the hood continue to spin and dont stop unless i remove a battrey terminal

You first need to scan the computer for any stored codes, these codes will help in pin pointing the problem, if there are no codes then i would take a look at the fan relays and then coolant fan sensor and coolant temp sensor, this sounds like the cooling fan sensor is bad, also one more thing is that the relay is like a module and they do good bad often, hope this helps.

I need to find the coolant fan sensor on a 2000 chevrolet malibu.

It doesnt have a fan sensor per say. It uses a coolant temp sensor which is located in the lower intake manifold which relays temp to computer which controls relay circuit to fans.
