      Has anyone personally installed a thermostat in their Sport?

      1. Where did you source yours?

      2. Part number please?

      3. Where on the Sport is the T-stat located? pic?

      4. Was it difficult to change?

      5. Did you have to "burp" the system when you refilled the fluid?


      Thanks, John

      3. Right under where the intake splits into a Y.
      4. Very easy, took me 5 minutes
      5. I didn't need to "burp"

      Thanks for all the answers....I really appreciate that.

      So why is a thermostat $63.00?

      I'm sure I'll bite the bullet and lay out the cash.....just seems high for that part, yet if its the best option, that's not much in the grand scheme of keeping our engines cooler.

      I can only guess because it's such a low production piece, I couldn't answer that question other than I was amazed when I bought mine awhile back.

      When they were first developed for the 03-04 SVT Cobra it was a combo of 2 actual thermostats. In order to get the right size with the proper spring rate two of them needed to be disassembled and put back together with a combo of their parts.

      I'm not sure if that is still the case. Maybe they were able to source the proper spring by itself now. But either way its a better thermostat and the only one out there that is the proper fit, so thats $$.

      Educate me please

      Why does Ford want the engine to run hotter?

      Short answer.. Better emissions.. And its not just ford.. There are quite a few modern vehicles out there that "normal" temp is > 200F.

      And just for future people reading the thread and thinking can just toss a lower temp thermostat into vehicles.. Don't..

      You need to make sure your letting the vehicle get up to temp. What is "up to temp" is determined by the ECM of modern vehicles.. As long as your Tune and you engine temp jive your ok but if you drop the temp too low the vehicle will never think it reached operating temp and can throw codes, fail emissions etc.

      Sorry for the stupid question, but what's the point of changing the thermostat?? Does it really make that much difference? I just ordered the Lund tuner btw.

      My tstat i ordered with 93 tune from livernois is 160 deg..should help prevent heat soak in combination with my tune. I am going to run a tune without the tstat until i can in stall it in a couple weeks and then will switch to the tstat tune

      Anyone run a 160* thermostat + tune ?

      Shipped a tuner to Livernois for a performance tune and they called me to ask if I had a thermostat... presumably so they could include the fan temp modification (kick on fans when tstat opens at 160 vs stock). I didn't have a thermostat so they didn't include that option. I DD my XSport and will have it for many years... in the past, vehicles I've added tstats to didn't heat up as quickly in the winter and took a long time for the HVAC to get warm. Trying to keep it as driveable as possible in the NE Ohio winters... and so my wife won't complain. :)

      Don't use such a low temperature thermostat. I have it in my 1995 van. My temperature gauge never shows that the engine is warm. Your computer is calibrated for an engine temperature of 197* F. Do a search for open & closed loop operation for more information.

      Found this thread with the "search' feature and moved yours here. There are a few others as well.

      Thanks Peter. I can always count on you to consolidate threads. ;)

      I agree I think 160 is too cold. I'll probably run a tune without thermostat for now until see how it goes.

      Tuner just arrived today! Can't wait to take a look. It's like Christmas!

      Did you need to drain any coolant?

      I'm coming from the Fox Mustang world where for a long time changing the stock thermostat out for a 160 or 180 degree aftermarket part was a universally accepted as a worthwhile modification.

      There's not many people now who would recommend going below a 180 since the consensus is that the engine isn't operating at optimal temperature as explained here:

      Low Temp Thermostats: What’s the Advantage?

      Is there something unique about the EB engines that make a 160 thermostat a good idea?

      I recently installed a 160 degree thermostat from Livernois, and my temps still range from 170 to 190 so I'm not even sure the thermostat is effective. I was also given the tune that would trigger the fans earlier so I'm not quite sure it is effective as well. That being said I haven't stood outside the Ex to see at what temperature the fans kick in to know for sure. For the temperature every once in a while it will drop to 170, and you can visually see a change in the dummy gauge on the dash. I monitor all this through Dash Command so I can get a numeric result.

      That makes sense. I'm interested in purchasing the Livernois 93 tune but I don't think I would opt for the thermostat based on your feedback.

      I've been selling custom Stant 170° thermostats for several years - mostly to the Mustang & Cobra crowd (same one fits the Explorer). For $38 shipped - the one here - they are a great bang for the buck. Stant is the OE supplier, by the way. No need to pay $60-70, especially since some of them do not fit correctly. the 170 is perfect for these engines since it will allow for a more stable temp. I use the same one in my Whipple-powered Terminator (hence the Termi-Stat name).
