Thermostat Replacement and Repair

A car's thermostat is a modest and often overlooked component. It does, however, serve a crucial purpose by regulating the temperature of the engine coolant valve. As a result, when it quits working, the vehicle engine might overheat and stop working. As a result, as soon as this thermostat begins to fail, it should be changed as soon as possible.

The Role of the Thermostat

When you start the engine, the thermostat is in the closed position to assist it attain operating temperature. It starts to open when the temperature of the coolant rises. While the water pump pumps lower-temperature coolant from the radiator into the engine, the opening enables hot coolant from the engine to flow into the radiator. The expanding fluid begins to contract when the lower-temperature coolant reaches the thermostat container, closing the thermostat's valve.

The radiator thermostat, however, never entirely closes or fully opens during engine running, but progressively approaches either state to manage coolant flow, depending on engine operating circumstances. This enables the engine to run at its optimal temperature. This optimal engine operating temperature achieves a number of objectives: It aids in the proper lubrication of engine oil as well as the removal of hazardous deposits. It helps to improve engine performance while lowering pollutants and gas consumption. As a result, the thermostat has an influence on the health and durability of your engine.

Housings and Gaskets for Thermostats

Internal combustion engines work best at specified operating temperatures and being too hot or cold might compromise a vehicle's dependability. Our wide selection of high-quality thermostat housings and gaskets will keep your vehicle running at its best temperature.

A thermostat, which must be protected from the heat of the engine, monitors and maintains engine temperature. A tiny pellet of wax is used in automotive thermostats, which melts and expands at a specified temperature, opening a cooling valve when the ideal temperature is surpassed. Because of the high sensitivity of this design, a good thermostat housing is required, as even the tiniest break can cause serious engine damage. Old and worn thermostat gaskets can also create temperature difficulties within your engine, and they're sometimes more difficult to identify. Gaskets of high quality are essential for safely and securely sealing your thermostat and it’s housing together. To guarantee that you get the appropriate fit for your car, we chose high-quality thermostat housing and gaskets.

Is it safe to drive with a faulty thermostat in the engine cooling system?

No. If a thermostat problem has been identified, it should be addressed as soon as possible. Failure to do so might result in serious and costly engine damage.

Keep this in mind when changing the engine cooling system thermostat

Overheating caused by factors other than a broken thermostat will harm the thermostat. If the engine overheats, always replace the thermostat, even if the thermostat was not the cause of the overheating.

Whenever you have extensive maintenance done on the coolant system, the thermostat should be replaced. It is convenient and inexpensive during such repairs and preventative maintenance.

The finest thermostats to use are OEM thermostats, and you may ask your technician to install only OEM thermostats. OEM thermostats from the dealer are occasionally more expensive, but they are usually of superior quality and are designed particularly for your vehicle.

In a vehicle, where is the thermostat located?

The thermostat is a tiny mechanism that lies between the engine and the radiator in each liquid-cooled vehicle engine. In most vehicles, the thermostat is roughly 2 inches (5 cm) in diameter. Its duty is to prevent coolant from flowing to the radiator until the engine has reached operating temperature.

What are the signs and symptoms of a thermostat that is stuck?

A jammed open thermostat causes the heater to take longer to achieve normal operating temperature and only blast warm air. Engine overheating and radiator boil-over are signs of a jammed closed thermostat. Yes, they have the ability to stick open or closed.

What are the signs that your thermostat is stuck open?

When the heater is switched on, time how long it takes the engine to warm up sufficiently to provide heat. If the heater takes more than five minutes to heat up, the thermostat is likely jammed open, allowing all of the coolant to flow all of the time.

What is the purpose of a thermostat housing?

A thermostat housing's primary function is to house the engine thermostat and provide a coolant outlet to the radiator. Each radiator hose may be linked to a similar-looking housing, with one functioning as a coolant intake and the other as a coolant exit in some situations.

How do mechanics replace the thermostat in the engine cooling system?

When the engine is absolutely cold, unscrew the radiator cap and drain enough coolant from the radiator to bring the coolant level below the thermostat housing.The thermostat and gasket are withdrawn from the thermostat housing. It's worth noting that some automobiles have two cooling system thermostats, one of which may need to be replaced. Old gasket material is removed from all attachment surfaces on the thermostat housing. A new gasket is replaced, and the thermostat is reinstalled in the proper configuration, with the temperature detecting cylinder facing the engine. A calibrated inch-pound torque wrench is used to tighten the thermostat housing bolts to original equipment manufacturer (OEM) requirements. The cooling system is completely drained of all air and replaced with the proper coolant type.

The vehicle engine is run until the usual operating temperature is attained, and the coolant level is rechecked while ensuring there is flow through the radiator either visually or with an infrared temperature gun, taking precautions with the hot coolant. This will verify that the thermostat is turned on. Last but not least, the engine is inspected for leakage.

Free Collection and Delivery with Thermostat Replacement

Having to bring your vehicle to the garage if radiator thermostat not working is sometimes the toughest part of getting it fixed. As a result, we are pleased to provide a free collection and delivery service to our clients. If you schedule a collection, we will pick up your vehicle from your home or place of business, drive it to our facility, do any required work (after consulting with you), and return it to you at the end of the day.

For a modest cost, we can tow, jump start, or repair your car if it is having troubles or has broken down. If we are unable to start your car, we may arrange for a local recovery company to collect it at a very reasonable cost. Don't want to ruin your day off? You don't have enough time to get your vehicle serviced or repaired? Do you have trouble getting to and from your garage? With our Free Collection and Delivery Service, we can collect from either your place of work or your home location, and we feel we provide a valued product at Car Service and Repair.
