Thermostat replacement

A thermostat is a valve whose function is to open and close at certain temperatures and is part of the engine cooling system. The main task of the thermoelement is to regulate the engine cooling temperature. It is this unit that allows you to gradually and quickly warm up the power unit. During cold weather, this is especially important, since rapid heating of antifreeze is carried out first in the motor and heater, without additional cooling by a fan.

When starting a cold engine, the valve is in the closed position. Antifreeze circulates inside the engine and heater using a pump. At this time, the liquid temperature is not yet sufficient to open the valve.

Gradually heating up, the antifreeze reaches the opening period at the engine operating temperature. This happens due to the thermoelement. An open valve allows antifreeze from the engine into the radiator, equalizing the temperature due to cooling by the fan and air flow.

Manufacturers equip cars with different types of temperature controllers. This is due to engine power, the internal pressure of the cooling system, and the volume of liquid.

The main types include:

Simple single-valve option. Is the most common.
Two-stage. Such thermostats are often installed on cars with high pressure inside the cooling system.
Two-valve. Can control two coolant flows.
Electronic. New, modern type of thermostats. Adjustment via on-board computer.

Malfunctions in which the driver should contact a car service for diagnostics and further repairs.

All types of thermostats experience the same problems. They are related to the operation of the valve.

The valve remains in the seat without opening when the opening threshold is reached. This occurs due to oxidation. When water gets into the antifreeze, the water oxidizes the thermostat housing due to exposure to high temperature. Jamming in the closed position leads to rapid heating, followed by boiling of the antifreeze.
The valve does not block the circulation. The cause is dirt getting into the seat or a broken valve spring. Such a malfunction leads to a long heating of the engine.

If you find problems, just contact a car repair shop for diagnostics and repairs.

The thermostat cannot be repaired and must be replaced. Professionals will quickly and efficiently complete the job of replacing the thermostat. After repair work, a complete replacement of the coolant is recommended, and it is also important to ensure that there is no air lock, which could cause the new thermostat not to work.

Engine Temperature Light

The engine temperature warning light basically says, “We’re overheating.” Commonly, the car might be running low on coolant. But it can also be an airflow clog-up, broken fans, or leaks.

Are you noticing the engine temperature warning light on your dashboard? This light is an essential indicator of something wrong with your vehicle. But don't worry; paying attention to your car's behavior and understanding how to communicate it with your local auto shop helps you assess the problem before it worsens.

In this article, we're going to focus on common causes of the engine temperature warning light. We'll also give you tips on communicating with a mechanic in case you seek professional assistance. So don't wait; read on and better understand your car's needs.

Car Overheating

An overheating car sends obvious signs of danger: steam from the hood, foul smells, and the frightening sight of your thermometer in the red zone.

Automobiles are designed with the engine's cooling system to be effective. Engines run off flammable fuel, motioning various parts at incredible speeds. As a result, they generate tremendous heat in the process and need to be cooled to run safely.

Your vehicle has indicators to warn you of an overheating engine, like the engine temperature gauge symbols on your dashboard. Still, even the indicators won't run well if your car's cooling system is working badly.

Your vehicle's systems for regulating engine temperature include fans that run through the engine, the radiator, and the air conditioning system that vents into the interior. This means that engines overheat when heating or AC systems develop an internal temperature control problem.

Several issues might lead to overheating, but they're all serious problems. First, overheating vehicles are flat-out unsafe to drive. Fortunately, there are resources at a technician's disposal to find the trouble's root cause.
