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 ...

Q: My 1999 Pontiac Sunfire coupe is doing something something I can't easily explain. The car has 240,000 km on it and it has the stock engine, although I think I bought it with a K filter charger.

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 ...

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 ...

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

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 ...

Internal combustion engines — including those that run on diesel fuel — rely on various systems, accessories, and electronics to keep the pistons moving and your wheels turning. Of those systems and ...

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 ...

In the classic air-cooled VW boxer engines—and even current motorcycle, ATV, and aircraft configurations—engine cooling is achieved through airflow alone. Cast cooling fins, surrounding cylinder ...
