An Engine Coolant Thermostat only, housing not included.
- Supports your engine's optimum operating temperature
- Helps regulate the flow of coolant between engine and radiator
- Replace when malfunctioning
Many modern cars, trucks, and SUVs depend on a fluid called antifreeze or coolant to remain at optimal temperature. Coolant circulates heat away from the engine and outside of the car. The Engine Coolant Thermostat helps regulate the flow of coolant between the engine, where heat begins, and the radiator, where said heat dispels.
Your Engine Coolant Thermostat is a small but mighty contraption that opens and shuts according to changes in engine temperature. When you first turn your INFINITI on, the Engine Coolant Thermostat stays closed, containing coolant flow until the engine heats up to optimal operating temps. Once your engine is sufficiently warm, the thermostat opens, allowing coolant to circulate, helping curb the risk of your engine overheating.
By supporting your engine's ideal temperature, a working Engine Coolant Thermostat helps prevent engine damage and decrease emissions. Unlike engine oil and brake pads, coolant thermostats don't need regular replacements. Instead, these thermostats only need to be changed if they quit performing as they should.
A few telltale signs that your thermostat is malfunctioning include: engine overheating, the engine not coming to temperature, subpar cabin heater performance, or even a check engine light, in certain vehicles. In some cases, an old Engine Coolant Thermostat may lead to erratic changes in engine coolant levels or premature coolant deterioration.
Because many symptoms of a bad Engine Coolant Thermostat resemble signs of other cooling system problems, we suggest getting your INFINITI inspected at an authorized service center. But, if you're sure that the Engine Coolant Thermostat is the source of the problem, replacing it with a reliable OEM part could help get your engine back up to speed.
Typically, replacing an Engine Coolant Thermostat is a job best left to certified INFINITI technicians. But if you're an excellent DIY mechanic, you may be able to do it yourself. Prior to starting, make sure you have the right components and tools handy: an authentic INFINITI Engine Coolant Thermostat replacement, a new gasket or sealing compound, a wire brush, bucket, protective gloves, and a socket wrench.
Whether you decide to replace your Engine Coolant Thermostat at home or pay a visit to your closest INFINITI technicians, double-check the owner's manual before doing any work on your vehicle. In addition, ensure proper fit and excellent performance by purchasing an authentic Engine Coolant Thermostat and other Cooling System parts made by INFINITI for your INFINITI model and year.
