The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

When I built my first serious race engine, a Honda B18C with Toda high-compression pistons and camshafts, a knife-edged crankshaft, a Supertech valvetrain, and a ported cylinder head, I threw a ...

Engineers design modern engines to run in a narrow temperature window where power, efficiency, and emissions all line up. The thermostat sits at the center of that control, opening and closing a ...

Regularly checking your car’s coolant during summer is essential to prevent engine overheating and costly mechanical damage.

So your car’s temperature gauge is acting up, or not working at all, and you want to fix it? Good for you. Your car’s engine temperature is vital to its operation, and a properly-operating gauge is a ...

In most automobiles, heat is inevitable. That's because an internal combustion engine (ICE) powers most vehicles. In an ICE, fuel burns to create power, and the process releases heat. A lot of heat.

One of the oldest Mustang gripes we can think of is engine overheating. We can write this problem off as one of the penalties of old car ownership, but classic Mustangs were cursed with overheating ...

A car’s thermostat typically requires replacement only if it fails. Symptoms of a faulty thermostat include the car’s engine not warming up enough to run properly and generate heat in the cabin, ...

The radiator is a key component of the cooling system whose main responsibility is to cool the mixture of antifreeze and water that circulates throughout the engine. Related: What Is Coolant and Is It ...

This Propylene-based engine coolant lives up to most of the company claims based on my testing so far. In my 2019 KTM 790 Adventure, the temperature ran 8 to 10 degrees Fahrenheit lower than the OEM ...

Open the drain valve (drain cock) at the bottom of the radiator and let the existing coolant flow out by gravity. Then refill ...
