Types of Car Alarms

Two common types of car alarms are passive and active choices. The passive system is set automatically every time the key comes out of the ignition and all the doors are closed. The active system requires the driver to physically turn it on when passengers have left the vehicle. Passive systems are more securely sound in that the driver does not always have to remember to turn it on every time they leave the car. However, active systems are useful in that if the driver forgets something inside the car, they do not have to deal with the security system going off when they try to get back inside the vehicle.

Engine immobilizers, which are electronic security devices that are placed inside an automobile engine, prevent the whole machine from being hot-wired and stolen. These devices work by keeping the engine from starting unless the key is present. This prevents criminals from being able to manipulate the wires of automobiles and hinders theft.

Another common system is the audible alert, which blasts the horn and flashes the automobile’s lights when the sensors on the vehicle are set off. The sensors’ sensitivity levels can be adjusted to be very sensitive to any slight movements or to only go off when a significant movement is felt. This system is useful because of the ability to adjust the sensors depending on the environment the driver is in and because if someone attempts to break inside, the horn will go off, and the lights will flash. The commotion will attract the eyes of anyone else that is around, and the criminal will most likely be scared off.

With the many recent advancements in technology, companies have been able to develop silent car alarms, which alert the driver through their mobile phone when the ride is being tampered with. When the sensors around the automobile sense movements, the driver will receive a call that suspicious activity is occurring and that someone may be attempting to break into their vehicle. This system allows the driver to call the police when they receive an alert on their cell phone so that the criminal may be caught and arrested.


Signs of Car Radiator Failure

Coolant Leak

If you notice coolant on the ground beneath your vehicle, you have a coolant leak. Coolant leaks are caused by a leak in the radiator. Radiator fluid, known as coolant, flows through the engine and the radiator, so if it is dripping onto the ground, it is a sure sign that the radiator has a crack or opening somewhere. A professional auto repair shop can accurately locate radiator leaks with a specialized test using pressure and dyes.

Low Coolant

If you begin to notice that your coolant is always running low, or your “low coolant” light comes on, it may be due to a radiator leak. Although it can be tempting to simply refill and forget about it, it is important to put your schedule aside and have your radiator inspected by a professional mechanic. A radiator leak can be dangerous for many reasons, so it is necessary to repair them if one exists.

Discolored Coolant

Radiator fluid should be yellow, red, or green at all times. However, when the cooling system begins to go bad, the fluid can start to turn to rusty or oily colors, such as black or brown. Overtime, this oily fluid turns into sludge inside the radiator, which prevents the coolant from flowing properly. When this happens, it slows performance and reduces efficiency. Unfortunately, a radiator will need to be replaced if sludge gets inside.

Overheating Engine

Since the radiator’s job is to regulate the temperatures produced inside an engine, it is no surprise that an overheating engine is a very common sign of radiator failure. If the engine overheats just one time, it could be due to something minor like being low on coolant. But if your engine is overheating regularly, it could be a more serious repair. The more times you allow your engine to overheat, the more damage is done to your vehicle. It is important to get them repaired as soon as possible before they can get worse.
