Non mustang tech: but need help

[Shiroelex]

Since his car is overheating because of the fan not coming on as it should, I would have first suggested the coolant switch. Now that you have replaced that to rule it out, you need to make sure that coolant is actually touching it. That sensor does what it's supposed to based off of coolant temperature, and if there isn't enough coolant in the system to even make it to the sensor, then it won't work right. That, or if the system hasn't been bled properly and there is too much air in there. Another possibility is the system has a pressure leak somewhere, and is not coming up to the proper psi. If the thermostat is crappy, it won't let the system pressurize. Touch all of the hoses after the car is warmed up. Are the upper and lower radiator hoses, and both heater core hoses warm? Is the upper radiator hose rock hard when it is running? Does the system pressurize when it's running, and does it hold the pressure for an hour after the car has been shut off? I wouldn't jump to rigging up the fan to the fuse box just yet, if this is going to be your daily driver. It's hot as crap out there right now, and you definitely want your cooling system to be in tip top shape, if you need this car to run reliably.

*EDIT*

The sensor you replaced had two wires, right? I know the two sensors are near eachother right by the EGR; this one should have been the lower one.

yeah the system pressurizes fine the coolant level is fine and when you pull the sensor the coolant comes out like mad from the head behind the sensor.

I replaced the right sensor because it is the one closest to the firewall and has 2 wires coming out of it the other sensor controls the temp going to the gauge in the car.

So I am really stumped on why this the coolant sensor change didnt work.

You didnt by chance buy the sensor from autozone did you?
If not what brand is it, Ive seen my fair-share of defective parts.

I bought the part from NAPA because autozone doesnt know a damn thing.

I even checked the part number i had on the box to the online parts and its the right sensor. So i dont know what the deal is

Might take it to my mechanic down the street he might be able to figure it out.

NAPA carries good parts, Echlin make good stuff...

Taking it to a shop is a good idea, good luck bro.

there is a CEL so i may see what that says and maybe i can get a better diagnosis from that

but my mustang may be leaving me tomorrow so I need to get this thing going especially with the heat
