Select Your VehicleKia car, truck, or SUV enthusiasts have come to expect a certain level of best-in-class value when driving their Optima around town. While it may not be difficult to locate replacement parts for Kia vehicles, these days only the absolute best are required to repair your car or truck. When your Kia Optima rolled off the assembly line, it was destined for a driver who prioritizes economical pricing in their automobile. It's not every day that you discover you need a replacement Thermostats to repair your vehicle.

The function and purpose of Thermostats.

Your car or truck has a water-cooled motor, and its thermostat keeps the coolant flowing in the right direction so that your engine can maintain a constant and ideal operating temperature. On start-up, the thermostat remains closed; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches an ideal temperature, your Kia Optima thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Kia Optima engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

Why put it off... make your purchase while supplies last.
