Can coolant get into an air filter
Prevent engine damage
There are many possible causes for engine failure. In addition to technical defects (e.g. broken injection nozzle), incorrect designs are increasingly causing costly repairs. However, out of ignorance, many motorists also do not treat the engine correctly and thus provoke expensive damage. You should absolutely avoid the following mistakes!
Error 1: Do not check fluid levels
Not only regular checks, but also regular engine oil changes are important.

When replacing a cylinder head gasket, the engine must be dismantled.
Error 2: Failure to adhere to the maintenance intervals
How long an engine lives depends above all on maintenance. Unfortunately, many car owners want to save money here and exceed the maintenance intervals. While old engines often did not cope with this so well, an excessive oil change in a modern car can lead to expensive damage. On the one hand, this is due to the maintenance intervals, which are becoming longer and longer anyway, and on the other hand, it is also due to increasingly sensitive technologythat is installed in modern engines. Incidentally, depending on the driving style, the maintenance intervals specified by the manufacturer are too long. While an oil change interval of 30,000 kilometers may be suitable for a long-distance driver, it is already too long for a short-distance driver, even with good engine oil. Fuel gets into the oil over short journeys, it gets dirty and loses its lubricity over time.
If the timing belt breaks, the pistons and valves are often severely damaged.
Mistake 3: ignoring defects and noises
A car never repairs itself - but many drivers seem to think so. Not infrequent unusual noises or warning lights come on (especially the yellow engine control light) is ignored. This is a big mistake, because warning lights rarely come on for no reason. Lights the Engine control light with the engine running, there is usually something wrong with the combustion. One of the reasons for this is that an engine misfires or is sucking in air, but sometimes there is defective lambda probe or a broken air mass meter gives a wrong signal. In any case, the error should be found as quickly as possible. Because of all these errors, the mixing ratio between air and fuel is not correct. If too much fuel is burned ("engine is running too rich"), it washes the oil film from the cylinder walls, and this leads to greater wear - at least in the case of gasoline engines. If too much air is added ("engine runs too lean"), the engine can overheat or pistons or valves burn away. The engine control lamp flashes, then there is usually somewhere fatal error before, and you should turn off the engine as soon as possible. Even if the red oil warning lamp lights up, the journey should be interrupted as soon as possible. Then something is right with that oil pressure not, and the engine would be very badly damaged after less than a kilometer.
Same goes for strange noises. Does the water pump have one audible bearing damagethat is ignored, it can eventually fail completely. If you are lucky in an accident, you will notice it in time rising temperature display and turns off the engine. With bad luck, the engine overheats, or the water pump blocks and lets the toothed belt skip. Incidentally, this can also happen when a pulley or tension pulley says goodbye. But in most cases they also loudly announce their failure.
Error 4: Do not warm up the engine
Not only do competitive athletes have to warm up slowly, the engine also needs a certain amount of time to get on the correct operating temperature get. If the engine is still cold, that is too Engine oil essential more viscous than when at operating temperature. Therefore, if possible, you should never turn off a cold engine, but instead Warm up carefully. If the oil is still viscous, there is a risk that the oil film will tear off and the engine will wear out much faster. Even after Cold start you should too do not drive off immediately: When an engine has been switched off, all the oil collects in the oil pan. As a result, an engine needs some time to build up oil pressure and to be able to properly lubricate the cylinder head. A little trick: First start the engine, then buckle up and only then drive off carefully. The short time should be enough to build up the oil pressure. On the other hand, you shouldn't let the engine warm up. If an engine is cold, more gasoline is automatically injected. This "excess" gasoline washes the oil film from the cylinder walls and thus promotes wear. That's why you should It is also better to leave the car behind for short journeys and take the bike or bus instead. This not only protects the engine, but also the environment.
Error 5: Stop the engine when it is hot
Another deadly sin that many drivers commit, especially after driving fast: they make you overheated engine immediately off. Especially after driving fast on the motorway or after driving under high load, an engine should still be left running briefly to cool down a bit. If such an engine is hot and it is switched off, the Warping cylinder headeven though there is enough cooling water. But also for one turbocharger Immediate parking after a fast stretch of the motorway is harmful. When driving at full throttle, such a turbocharger is approximately 1000 degrees Celsius heated up. If you then turn off the engine, cokes the oil and clogs the oil passages. This in turn leads to insufficient lubrication, which causes the turbocharger to wear out more. At a defective turbocharger there is also the risk that it will at some point feed the engine oil for combustion via the oil ducts. Especially with diesels it can lead to the engine running for so long uncontrollably gives full throttleuntil there is no more oil in the engine and it seizes up.
Error 6: Drive too high speeds
In order to protect the engine, it should not be turned into the red area too often if possible.
Error 7: Using the wrong fuel
Refueling the wrong way can result in major engine damage.
Error 8: water hammer
A water hammer can not only hit off-road vehicles that are currently crossing a large water hole in the field. It can be especially after heavy rain normal cars get caught on the street. Of a Water hammer you talk when an engine Sucks in water instead of air. When the water then gets into the combustion chamber, it is usually too late: unlike the fuel-air mixture, water cannot be compressed and brakes the piston abruptly. The result: mostly the connecting rods bend, Damage to the crankshaft, the cylinder head and the engine block are also not uncommon. Since many cars suck in air relatively low down, you should Avoid driving through large puddles if possibleso as not to risk expensive engine damage.
