Original Equipment Thermostat

THERMOSTATS

The thermostat in your car does much more than meets the eye. Its two most important jobs are to help your car’s engine warm up faster and to regulate the temperature that the engine operates at. But a thermostat that is high-quality, like Stant thermostats, can also help to do other things.

It can help your engine last longer: precise engine temperature control means more efficient engine operation and longer engine life. It can give you better mileage: the engine operates at more stable temperatures, which results in improved fuel economy, reduced oil consumption, and fewer emissions. It precisely controls the amount of coolant that passes through the system. Stant thermostats are built tough of durable stainless steel for long life and maximum performance.

Stant thermostats have technology that has proven strong and reliable in millions of vehicles for billions of miles.

Once again, Stant’s experience as an OE (original equipment) supplier speaks for their innovation in design and technology. A large percentage of OEM (original equipment manufacturers) count on Stant thermostats.

Stant thermostats are tested extensively in-house to meet stringent OEM requirements including: life cycle durability, vibration, leakage, corrosion/erosion, extreme temperatures, and more. Stant thermostats are the thermostat of choice of OEM’s, installers, and consumers.

Stant thermostats are powered by a temperature-sensitive heat motor. Heat causes a wax pellet to expand, forcing the piston outward, which opens the valve of the thermostat. The heat motor “senses” temperature changes and opens and closes the valve to control coolant temperature and flow.

The thermostat allows proper warm-up of the engine when starting. Slow warm-up causes moisture condensation, which finds its way into the crankcase, causing sludge. Stant thermostats keep coolant temperatures above a designated minimum required for efficient engine and emission control performance. It also prevents the metal around engine hot spots from overheating during warm-up by allowing coolant to circulate internally through a “bypass” before it opens.

Stant thermostats start to open at a specified temperature, which is normally 3 to 4 degrees above or below its temperature rating. Thermostats must fully open at about 20 degrees above the “start to open” temperature. They must permit a specified amount of coolant to flow when fully open and leak no more than a specified amount when fully closed.

Most thermostats today feature either a “bleed notch’ or a “jiggle pin” These devices are designed to let trapped air in the system pass through the thermostat after refilling to eliminate engine “hot spots” during warm up. Only a specified amount of coolant is allowed to leak through the bleed notch or jiggle pin.

Since 1971, most domestic car manufacturers have used 192 F or 195 F thermostats as original equipment. This permits the engine to operate at a higher temperature, which allows the cooling system to operate most efficiently and better control emissions. When replacing the thermostat, be sure to use the same temperature thermostat as was used for original equipment. The thermostat should always be checked when performing routine cooling system maintenance.
