About Coolant Temperature Sensors
Part of the car's cooling system, the BMW coolant temperature sensor plays an important role in enabling the engine to function as efficiently as possible and to perform at its best. The main function of the cooling system is to keep the engine cool and stop it from overheating. The cooling system does its job by allowing liquid coolant to move through the engine. The liquid absorbs the heat from the engine which in turn cools the engine down.
The BMW coolant temperature sensor's job is to measure the temperature of the liquid coolant. This information is sent to the car's ECU, which uses it to manage the operation of fuel injection, ignition timing, transmission changing and variable valve timing. Essentially, the coolant temperature sensor warns the car's ECU if the engine is overheating. In some vehicles the coolant temperature sensor also functions to activate the electric cooling fan and can supply information to the coolant temperature gauge which provides readouts to the driver.
The coolant temperature sensor is usually located in one of the engine's coolant passages, normally close to the thermostat.
If there is a problem with the car's cooling system and the coolant temperature sensor has malfunctioned, the warning light is triggered on the dashboard. Coolant temperature sensors can malfunction due to faulty electrical connections and corrosion. A faulty coolant temperature sensor can affect the fuel injection, ignition, and transmission systems and should be addressed as soon as possible to avoid damage to the engine and mechanical parts. Signs of a broken coolant temperature sensor are the engine overheating, higher fuel consumption, and black smoke billowing out of the exhaust. There are many problems that can arise with your car's cooling system so it is advisable to consult with your mechanic to establish the exact cause of the fault. Specifically designed for the make and model of your vehicle, the BMW coolant temperature sensor is the ideal choice when you need to replace this part.
- It might not be the accessory that everyone needs, but for BMW drivers in South Africa who were worried about carjackers, the 'Blaster' was a flamethrower that shot huge flames from either side of the car. Not currently available in the UK…
- Everyone knows what the BMW logo looks like, but do you know what it represents? Most people think it's inspired by propellers (because of BMW's aviation history), but it's really just the same colour scheme as the Bavarian flag and was designed to showcase Bavaria.
- The BMW 3.0CSL was sold in the 70s and had the unusual addition of a spoiler that was kept in the boot. The owner could install it if they wanted to, but BMW couldn't sell the car with the spoiler attached because of road laws!
- The BMW company was founded way back in 1916 and originally manufactured engines for planes. High demand for plane engines during WWI was good news for BMW, but they carried on making plane engines right up until 1945.
- The main headquarters for BMW in Munich is designed and shaped to look like car parts. There was a whole new 'four-cylinder' building added on in 1973, and there's definitely the look of an engine about the architecture.
