Crucial Racing Thermostat(Brand New)
I have a couple of thermostats for sale. Was 65 shipped. Want to get what I paid for but hit me up with an offer. Added bonus crucial sticker lol.
Here is a write up from Crucial Themselves:
Subaru's turbocharged vehicles place a lot of stress on the cars' coolant sytems. Not only does the coolant have to do the normal job of keeping the engine itself at proper operating temperature, but Subaru has given it the additional duties of cooling the turbocharger and the engine oil! Cooler coolant plays a huge role in the safety and performance of your Subaru on multiple levels.
The Crucial Racing Systems Coolsafe 160 degree thermostat forces your cooling system to react quickly to manage and reduce coolant temperature overshoot under high loads - which is critical to protecting your engine from heat-induced detonation. Before-and-after data logging on a very hot California afternoon showed max coolant temps under full throttle load of 195* F pre-thermostat, and 174* F after the install of the Coolsafe thermostat. Ignition timing is affected by coolant temps, as is the car's oil temperature. The simple addition of a Crucial thermostat will increase power output, especially on a hot day where you will notice less of a performance loss due to the outdoor temperature.
A high performance radiator will lower the coolant temperature at the exit of the radiator as it is a larger heat sink and can dissipate more heat. The stock thermostat, which opens at 172 degrees, is located at the entry of the engine block immediately after the coolant exits the radiator. When installing a more efficient radiator before the stock thermostat, the stock thermostat is actually slower to open than normal because the coolant passing through the bleed hole is colder than normal. If you suddenly go to high boost, the thermostat will not react until the coolant flow and temperatures get high enough at the radiator discharge to open the thermostat allowing for significant coolant flow. As Subaru engine coolant temperature sensors are located on the top of the engine block, coolant temperature is measured as it leaves the engine, not at the thermostat, so coolant exiting the engine under high load could be 40 - 60 degrees warmer than the 172 degree stock thermostat temperature and heat-induced detonation can occur. When your Engine management system senses detonation, ignition timing is retarded and your engine loses power.
The benefit of installing a Crucial Racing Systems Coolsafe Thermostat is definitely not limited to cars with high performance radiators! Automobiles with stock radiators will see the same benefit of lower coolant temperatures, lower oil temperatures (high oil temps are a common problem among cars that see occassional track use), less coolant temp overrun, increased detonation protection, and more power.
Under normal conditions, the Coolsafe Thermostat will operate like any other thermostat. But, unlike standard thermostats, our Coolsafe thermostat automatically locks into an open position should an overheating or failure condition occur, protecting the engine from serious damage. Any other thermostat will lock in the closed position; a sure way to serious engine failure! Although a thermostat cannot completely prevent cooling system failure, it can greatly improve operating reliability in emergency situations. It is a wonderful safety feature for your Subaru, and the added performance is a welcome plus.
Every Coolsafe thermostat is individually tested for proper function, quality, and comes with a Limited Lifetime Warranty.
Fitment - Every Subaru automobile manufactured since 1992 and the Saab 9-2x.
