Review of the Top 5 Car Sat Navs

Review of the Top 5 Car Sat Navs

Not too long ago, we all had our trusty maps with us, to show us the way to go. One wrong turn at some time in our driving lives convinced us that a map was an essential carry along, and now we have evolved to using Sat Nav’s in our cars.

The Nav Sats of today can either come as individual orders with many cars, but if you want choice, better quality, and better pricing, the best way to go is to purchase a Car Sat Nav as an after-market add-on, to include all the bells and whistles that your heart may desire.

In this article, we look at what we believe are the top 5 sold in the UK market. These are our personal choices, which you may not agree. But the review will, at least provide a summary of what some of the important factors are in making a purchase decision about which is the best Car Sat Nav for you.

Our Top Five List

Beginning at Number 5, we have chosen the Noza Tec GPS Sat Nav System. This handy unit, priced at 40.99 pounds, comes with a grand 7-inch screen and UK and EU Maps, with lifetime updates.

Short on fancy, fancy gizmos, this unit is worthy of our Number 5 position because of its reliable performance and its large screen.

Our Number 4 choice is the LUJII 5.0 Inch Touch Screen SAT NAV.

This System not only is a GPS but also is multimedia and FM friendly. It comes with maps for Europe and The UK and at a rock bottom price of 36.99 pounds, it just nudges out the Noza Tec GPS for Number 4 position.

And sitting in the middle of the pack, at Number 3, we have chosen the Tom Tom Start 25 Sat Nav System, which provide a 5 inch screen, good quality graphics and lifetime updates for its Western European map package that is included. The Tom Tom is a little short on added features, but for the price of 79 pounds, the quality, and the lifetime maps, this unit is worthy of being selected as our Number 3 choice.

This leaves us with Number 2, where we have selected the first of two Garmin Sat Navs. For second place, our pick is the Garmin nuvi 2518LT-D. This System has the same features as the 2569LT-D that is in our Number 1 position, with the exception that this unit comes only with maps for Ireland and the UK. This is reflected in the price of the unit, as well, listed as 94.95 pounds

And at the head of the class, we have selected the Garmin nuvi 2569LMT-D 5″ Sat Nav. The System checks in with a price of 129.99 pounds, but it certainly carries a punch with all its operating options. The Sat Nav comes fully loaded with UK and Western Europe Maps, with free updates for the life of the unit, as well as, it lets you know how traffic is doing with a free lifetime service, and you can keep your hands on the wheel with the Bluetooth feature.

Also, the map display at 5 inches is a great size and it can be pinched to zoom and the visual traffic delay display that shows up on the side of the screen is a real bonus.

Overall, although a little pricey, the nuvi 2569LMT-D is tops in our class.

Winter Driving Tips

Winter Driving Tips

It is absolutely terrifying for some of the people to drive vehicles during winter, especially when they live in an area with freezing temperatures which is combined with ice, snow and sleet. During winters, even one moment of inattention might put you in dangerous situation. Here are winter driving tips that you should know while driving in winter.


Winter Driving Tips

  1. Pay Attention: In bad winter weather, even the smallest lapse of focus can send us spinning off the road. You should always keep your phone switched off while driving in winter month. You should also not remove your hand from the steering wheels to change the radio station and should avoid eating or drinking behind the wheel. If you have your kids along with you in your car then you should teach them the importance of remaining quiet while driving you should teach them so that you are not distracted while driving.
  2. Maintain a Safe Speed: In winter, majority of accident occur due to excessive speed. It is very difficult to maintain the speed on icy and stormy roads. Due to excess speed, your tires will lose its grip on the road altogether.
  3. Keep your Car in Tip-Top Condition: You should get your car serviced and you should keep it in good condition always and get it checked regularly. This will prevent unexpected breakdowns and it will also allow you to drive safely on the bad roads. You will get maximum amount of traction by keeping the tires rotated and properly inflated.
  4. Know What to Do in Emergency: Do you know that what you should do in the event of skid or spin? There are different approaches that you should try depending on whether you have rear-wheel drive or front-wheel drive. You should learn how to handle your vehicle and practice your reaction so that you are ready. It is also very important for you to learn first aid skills and other such emergency response skills, including how to survive if you are stranded in snow.
  5. Pack a Safety Kit: You should always keep a stock of emergency kit in your vehicles such as fire extinguisher, first-aid kit, a tire gauge, battery-powered warning light or flares, lug wrench, jack, cables, tire sealant, battery charger, jumper cables, water, gloves, basic tools, warm blankets and energy bars.
  6. Visibility: While driving your vehicle you should make sure that you are able to see well. You should clean the inside as well as outside of the windows thoroughly. If you have old windshield wiper blades then you should replace it with the new one. You should also apply a water-shedding material on the outside of the windows.
  7. Avoid Icy Uphill Driving: You should try not to drive up hills when it is icy. If you cannot avoid it then you should go up slowly in second gear. You should steer around obstacles and should use feather braking in order to keep the momentum. You should not stop until you have cleared the top of the hill.

Car spark Plugs Explained

Car spark Plugs Explained

A car spark plug or k-plug, or a sparking plug is a device used for delivering an electric current from ignition system to a combustion chamber of any spark-ignition engine. It works by compressing air to mix with compressed fuel at the electric spark, where the combustion is under pressure in the engine.

A spark plug has an electrically isolated a metal threaded shell from central electrode through a porcelain insulator. This will always enable the car to have power needed when moving from place to another. Very heavy trucks often have central electrode that may contain resistors connected through wire that is heavily insulated right to the ignition coil terminal. The central electrode often works to the porcelain insulator to its combustion chamber to form spark gaps.

People use Spark plugs for other purposes such as direct Ignition when measuring ionization levels in the combustion cylinders. Many can also use it to replace ordinary knock sensor, misfire measurement and phase sensor function.

What are the parts of a plug that you should know?

Here are some of the parts of a plug that you should know:

  1. Terminal

Terminal is the spark plug top most part and contains a terminal that is connected to ignition system. This terminal construction often vary depending on what kind of spark plug you use. You can always choose from a wide range of options available in the market when buying.

  1. Insulator

Insulator is the main part of the engine made from a sintered alumina with very hard ceramic material of high dielectric strength. This will enable it to resist surface spark tracking. Its main function is always to offer an electrical insulation and mechanical support for its central electrode at the same time providing extended spark path for the flashover protection.

  1. Ribs

Ribs are the surfaces in between the grounded metal case and high voltage terminal of the spark plug. This physical shape often functions as way to improve electrical insulation at the same time preventing electrical energy that may leak alongside insulator surface from a terminal metal case. This makes it an important part in a car spark plug.

  1. Insulator tip

An insulator tip is the part of a combustion chamber made form aluminum oxide to enhance combustion. This part is always designed to withstand very high temperatures of 650 degrees C and 60 kV. They act as insulators to the car spark plug especially when it is moving at very high speeds. The insulator dimensions determines the metal conductor core and plug’s heat range.

. 5. Seals

Seals often prevent any loss of heat in the combustion chamber. It has to be kept tight to ensure that energy is conserved in the whole process.

  1. Metal case

The metal case of a spark plug can withstand the plug’s torque of tightening, at the same time serves by removing heat from insulator to pass it to the head of cylinder head, that sparks passes it on to the central and side electrodes.

  1. Central electrode

The central electrode is designed to reduce noise emission from the vehicle.

How to Change Your Wiper Blades in 5 Easy Steps

How to Change Your Wiper Blades in 5 Easy Steps

The windscreen wiper is one of the least thought about part of a car’s safety system. However, if the wipers are not working as they are supposed to it might be very difficult to see when it snows or on a rainy day. Faulty wiper blades can smear the windscreen and hence giving you visibility problems when driving and so it is important to make sure that they are always in good shape.

Changing a wiper blade may look like a daunting task especially if you have never tried it before. However, when you try it you will realize just how easy it can be, and so you will never have to visit a mechanic every time you have problems with wiper blades. To show you just how easy it is, here are the five easy steps you should follow to change your wiper blades.

Step 1: Inspect the blades

The first thing that you should always do is to check the blades. By checking the blades, you will be able to decide whether they need to be replaced or not. If the wipers smear or only clear a part of the windscreen, then the blades need to be changed. You can also check by running your fingers along the blade and if it is scared or feels notched then it needs to be changed.

Step 2: Lift and Swing

The next step is to remove the old wiper and to do this you will need to raise the wiper arm away from the windscreen. The wiper arm should be able to hold perpendicular to the windscreen, but you should be very careful with the positioning of the wiper. The wiper arm is fitted with a spring, and so it can snap back and crack your windscreen.

Step 3: Unhook the old blade

This step is easier than the others, but you should be careful to prevent the wiper arm from snapping back. At the joint where the blade meets the metal arm, you will see a small plastic stopper that holds the blade in place. When you press the stopper, the blade will unhook for you to remove it safely. However, it is important to know that some wipers might have a pin instead of a hook, and so you should watch out for this. During this step, one hand should be holding the wiper away from the vehicle’s windscreen.

Step 4: Attach new blade to connector

Unwrap the new blade and attach it to the connector. The blade should fit with ease provided it is the right size and design. Before attaching the connector to the blade, you should check to confirm that the connector is not damaged in any way. Even though the blade is new, you should also inspect it thoroughly before attaching it. Once the blade is attached to the connector, it will now be ready for the fifth and final step.

Step 5: Insert the new wiper

Slide the wiper into the same end of the wiper arm where you pulled out the old wiper. Gently push the connector into the hook until the wiper locks in place. Check with your hand to make sure that it is properly locked in place and then lay back the wiper to its original position. You can start the car and test the wipers to ascertain that they are working properly.

Symptoms of a Failing Car Radiator

Symptoms of a Failing Car Radiator

The car radiator is one of the most important gadgets in a vehicle. It constitutes or rather, it is a part of the cooling system. It prevents the engine from overheating a condition that could lead to permanent damage of the engine, piston or the entire cooling system. A majority of car radiators last for a long time. In the event the radiator is not functioning properly, fluctuating, symptoms such as overheating, radiator sludge, leaking coolant, drop in pressure, and rust

Overheating: This is one of the biggest problems of the radiator. When overheating occurs, the radiator does not cool the coolant before it is pumped into the engine. It is a potential trouble that results to fluctuation of temperature and can result to serious damages if not rectified. The problem of overheating can result from the failure of the fans. The dashboard’s temperature gauge rises above the normal limit when the temperature of the radiator is beyond normal. It is recommended to shut off the car if the problem is detected.

Leaking coolant: Leaking is noted by the presence of orange or green liquid under the car or even in the passengers’ compartment. Also, green or orange coloring and stains are seen on the engine, or on the radiator beneath the bonnet. Additionally, the coolant releases a certain smell when the engine is running. All these symptoms are an indication that the radiator is failing and need to be checked for repair or replacement. Most probably, the radiator is corroded and has a puncture(s).

Low coolant levels: Low coolant levels are associated with a leaking Radiator. Although the level of the coolant depletes with time, a sudden drop in the level of the same is not normal. In such a situation, the car owner should check the connections and hoses to ascertain they are tightly fixed.

Low coolant levels: The radiator may process low pressure than required if it has a lot of corrosions. At normal condition, the radiators should produce a pressure of between 10 PSI and 12PSI. If the pressure values are lower than this, the radiator has problem which need to be addressed. A pressure gauge can be suitably used to determine the pressure of the radiator.

Failure of the heater: Failure of the heater is noted when the heater starts to blow cold air. Presence of cold air is not an indication that the cooling system is functioning out properly. Normally, it is a warning that the cooling system has a problem. Lack of hot air coming from the vents, It is an indication that the coolant levels in the radiator are very low and are not circulating from the engine to the heater core.

Radiator sludge: Sludge forms when the radiator goes bad, rust or develops debris. When the fluid in the radiator is contaminated, it rust rusts. A rusty radiator is likely to cause flaking in the coolant, resulting to the formation of the sludge that does not cool the engine efficiently. The sludge never drains completely but remain in the radiator after a coolant flush. Its presence continues to inhibit cooling and needs to be replaced immediately it is detected.

The presence of any of the above signs in your vehicle, is an indication that the car radiator has a problem. If welding is required, ensure you have the correct equipment, including a good welding helmet and a welder that is suitable for the job at hand.
