          Comments about Stant Superstat Premium Thermostat, 195 Degrees Fahrenheit:

          This is a high quality thermostat that you would expect from stant. The only negative I would comment on is that it doesn't come with an air bleed hole to help fill you cooling system to prevent air pockets which can cause overheating. I always drill a 3/32 hole in all of my thermostats if they don't have one an fill the system with the upper radiator hose off to make sure that the new antifreeze comes in contact with the thermostat. This way you know the thermostat will open because it needs contact with hot antifreeze to function correctly. I worked on cars for over 20 years as a mechanic and taking the time to do this step saves a lot of heartache.

          Chose this thermostat because it is the highest priced Advance offered for my car. The thermostat did not come with a replacement gasket (was able to reuse the old rubber gasket). Also the thermostat does not include an air bleed off, so I had to drill a small hole in the thermostat housing to allow air to bleed out of the system.

            I paid extra for the lifetime warrantee but no gasket in the box! Luckily the old thermostat's was fine plus I used the blue sealant just in case. No leaks.

            Heats up much faster than the 185F thermostat and engine temp tops out at the same on the gauge (right in the middle). Should save gas!

            • Q:

              Will it keep a steady temp for the in cab heater and is it made to burp air out of the cooling system?

                Hi Mechanrex, I'm glad to assist you. This Stant Superstat Premium Thermostat, 195 Degrees Fahrenheit (Part No. 45399) has a patented V-notch, non linear design that reduces cycling by precisely metering the amount of coolant needed. The V-notch provides a small initial flow. As the engine heats up, the V-notch gradually open wider, metering coolant released into the system until the desired engine temperature is reached. The benefits of proper engine temperature control are as follows: efficient engine operation, prolonged engine life, reduced oil consumption, improved fuel economy and improved emissions. The thermostat uses a high flow venturi for maximum cooling capacity during high temperature high load operations, and employs a patented Weir Valve, for precision flow metering during cold weather light load operation, to ensure stable temperature control under all conditions.

            • Q:

              Does this come with the O-ring also? If not, what is the best P/n O-ring for this thermostat (2000 4.6L Lincoln Town Car)
              Thank you

                A:

                I'm happy to help, Kevin! This Stant Superstat Super Premium 195 Degrees Fahrenheit Thermostat (Part No. 45399) does not include an o-ring. On the 2000 Lincoln Town Car 4.6L V8 you may be able to reuse the o-ring that is on your current thermostat. If you need to replace it, the Fel-Pro Water Outlet Gasket (Part No. 35489) is a great choice.

                You may also need some coolant to top off the radiator or coolant reservoir. If your vehicle uses green coolant, Peak still has the classic Peak Conventional Green Antifreeze/Coolant (Part No. PKA0G3/12016). If your vehicle uses the orange coolant, you'll want a coolant that meets Ford Specification WSS-M97B44-D which is typically labelled as Dex-Cool, such as Prestone Dex-Cool Prediluted 50/50 Extended Life Antifreeze/Coolant (Part No. AF850).
