07 2.0 Thermostat With or Without the Sensor??

I have 2007 base model S the with 2.0 around 182k on it. CEL came on pulled the code and itís a P0128. Coolant thermostat. Coolant temp below thermostat regulation temperature. Is what my scanner told me.
Iíve noticed that in the past week or so the heat is definitely not hot anymore luke warm at best. I am assuming that I should replace the thermostat but when looking it up there are 2 different options. One with or without the sensor. I donít have the time to take the old one off to see if it has the sensor or not. I went onto fords website and put in my vin thinking that would narrow it down for me but both parts came up with and without a sensor. Anyone have any input on this? Iím thinking I might just have to order both and return the one that I donít need.
The coolant is clean did a full flush around 20k ago.

Thanks!

I have repeatedly asked & challenged FF members to show me a (2000-2007) Focus with a T-stat that has a sensor. No one has come forward with any info to prove this animal exists.

I have never seen a Focus "with sensor" or a Focus that has wiring provisions for the sensor. (2000-2007)

Coolant system temps are (extrapolated) calculated based on CHT sensor readings.

Gd Luck

If yours has the sensor you should be able to easily see the sensor/connector under the large water outlet port:





Without the sensor (no connector)

Yes it's the one with a sensor

Well I am pretty sure I do have the one with the sensor. I took a look and there is an electrical connector hooked up to it.

You might have a t-stat with sensor, but I can not see this in the pictures you posted. That bugger is hidden & is tucked away.

Careful, I do vaguely remember a connector in that exact area (on my car) but that connector does not connect to the t-stat. IIRC it is a floating harness connector which connects to nothing except the mating harness. I think that is what is shown in your pictures. Go look again.

PLEASE post back once you get absolute confirmation. Thanks!

To OP: i had the exact same problem. Garage wanted CAN 500$ to replace.

I took the plundge. I just finished replacing the T-STAT on my 2005 Focus. I dont know your skills, but here is what i did to EASILY replace the t-stat. The keywords are easily and t-stat. Because, its no easy job to replace a t-stat in that cramped space.

0) empty radiator using the cork driver side on the radiator

1) Remove/loose/replace serpentine belt
- remove serpertine belt protector case (from bottom)
- release tension using the tensionner bolt
- take off/replace serpertine belt

2) remove coolant reservoir
- unbolt coolant reservoir (1 bolt onto fender)
- slide it up (pin is toward windshield)
- put it aside

3) slide out p/s pump
- unbolt the 3 easiest bolts (you can see them)
- the fourth one is a bummer.... the p/s pressure sensor line is in the way
- using a 10mm ratchet/open wrench (buy/rent one youll need it), unscrew while pulling away the pump from its base
- slide p/s pump on the left

4) remove passenger side headlamp (it creates way more space to work on t-stat)
- remove two upper bolts
- one in the fender
- unplug connectors
- put it away

5) finally the t-stat
- detach the bottom end of the big hose going from t-stat to bottom of radiator
- leave the t-stat end of that big hose on the t-stat
- compress the clamp and remove the smallest hose from the t-stat
- you will now have easy access to the three bolts
- remove the t-stat as a whole with the big hose

6) putting it together
- rest the t-stat on a flat surface
- mark/scribe the relative position of the big hose onto the defective t-stat
- unclamp the big hose
- using the scribed marks, fit the hose on the new t-stat at the same position you marked it, making sure the clamp is a the exact same position it was

7) back to engine
- lube the t-stat gasket with coolant
- reposition the t-stat on the engine
- screw partially the the lowest bolt
- then the two upper ones
- check fitting of the hoses
- torque the t-stat bolts (89lbs)
- clamp the smallest hose
- clamp the bigger hose at the bottom of radiator

8) p/s pump reinstall
- this is the bummer
- you have to begin with the lowest passenger side bolt
- the space between the head of that bolt and the p/s pressure line is minimal, so you have to pull the pump toward the front of the engine while screwing mm by mm the bolt. Again, an 10mm open ratchet wrench is your friend. I did not have one, so i has to torque that bolt 1/8 of turn at a time.....

- - -

Again, this is not the shortest (time related) way to do the job, but its the easiest way to have full access to that delicate part - the t-stat.

i finally have heat!

And I used to b-tch about removing 2 bolts on GM ones to remove stats.............I was young and stupid................when you practically need a college education just to yank a freakin' stat, well, it's gettin' close to time for me to retire it seems.

I have to yank the intake manifold to change plugs on my Nissan....................(smoke coming from ears)
