How does fail-safe thermostat work?
When overheating is caused by a deteriorating cooling system part, the fail-safe has a secondary stroke that activates a precision engineered piston. This automatically locks the valve into a wide open position to allow coolant to circulate freely.

What is the jiggle pin on a thermostat?
The thermostat jiggle pin is a pin that is located in the small hole in the plate valve of the thermostat and which should always be in 12 o’clock position during installation. It helps bleed the cooling system of trapped air by allowing air to pass into the radiator, after which it can be released from the system.
Are thermostats designed to fail open?
Fail-safe thermostats are designed to stay open when they fail. This is not a perfect solution since the system will still run hot. Since the coolant cannot stay in the radiator long enough to cool enough, it will still allow the system to heat up and eventually overheat, but you will get a lot more miles out of it.
Is MotoRad a good brand?
The MotoRad name is synonymous with quality, reliability, comprehensive coverage of vehicle models and exceptional customer service.
Why do thermostats fail open?
Heat up a pot of water to the stamped temperature on the thermostat and use a pair of pliers to hold it under. You should see it open at the specified temperature, otherwise you know it’s bad. Thermostat failure can be caused by contaminated fluid or simply an old thermostat with weakened springs.
Why is there a small hole in some thermostats?
The little hole allows the air to escape. Some aftermarket stats come with it predrilled. The small hole will insure that you will not have an air pocket, and it will cause your engine to take a bit longer to reach its normal operating temperature.
What happens if you put a thermostat in upside down?
The water pump flow will push the thermostat open and cause it to take a long time to heat up. The stat will take longer to heat up if it is in dead zone and the thermostat is in correct orientation.
What causes thermostat to fail?
Thermostats fail because they become weak, stuck open or stuck closed. When a thermostat is stuck open, coolant constantly circulates and the engine takes longer to reach operating temperature.
Is MotoRad made by Stant?

Does drilling a hole in the thermostat help?
One is to let trapped air out of the engine and the other is to allow some water flow to let warm/hot water get to the thermostat motor before the engine overheats trying to open the thermostat. After the thermostat opens and starts regulating the engine temp the hole serves no useful purpose.
Is it good to drill hole in thermostat?
It makes it easier to burp the air out of the cooling system – the little hole keeps air from getting trapped under the thermostat.
What are the signs of a failing thermostat?
The temperature gauge reads high and the engine overheats.
Is it safe to run vehicle with a bad thermostat?
If it is failed in a closed position then you cannot really drive it with the thermostat broken, as the engine would overheat. This however will not generally have any impact on the ability to drive the car, at least if you let it warm up before you start driving. Similarly, it is asked, what are the symptoms of a bad thermostat?
Are failsafe thermostats any good?
Limited lifetime warranty.
How often do home thermostats fail?
How often should you replace home thermostat? The lifespan of most home thermostats is 10 years. However, you may need to replace yours sooner as newer, more efficient thermostats enter the market. You may, for instance, want to replace a non-programmable thermostat with a programmable option. Can you drive with a faulty thermostat?
