Thermostats and accessories for trucks

The function of the thermostat in your engine

The thermostat regulates the temperature of the coolant in your engine. It ensures that the engine warms up quickly and prevents it from overheating. This keeps your engine at the correct operating temperature for optimal performance and a longer service life.

How the thermostat works

The thermostat functions as a valve that regulates the flow of coolant. When the engine is cold, it remains closed so that the engine can warm up quickly. Once the engine reaches its ideal temperature, the valve opens and the coolant can flow through the radiator to cool down. This process prevents your engine from becoming too hot or too cold.

When to replace the thermostat

If your engine regularly overheats or remains too cold, the thermostat may be defective. An irregularly responding temperature gauge or a heater that does not produce warm air can also indicate that replacement is necessary.

Steps for replacing the thermostat

Replacing a thermostat generally involves the following steps:

• Allow the engine to cool down and disconnect the battery.
• Remove the mounting bolts from the old thermostat.
• Install the new thermostat correctly.
• Refill the cooling system with the correct coolant.
• Bleed the system to remove any air bubbles.
• Start the engine and check that everything is working properly.

Not sure? Have the thermostat replaced by a specialist.

Maintenance tips for your cooling system

By regularly checking your coolant and replacing it on time, you can help prevent thermostat problems. Proper maintenance of the water pump and radiator also helps extend the service life of your cooling system.
