Causes of Car Engine Overheating You Should Know

 The operating temperature of many modern cars falls within the temperature range of 195° F to 250° F. When temperature exceeds the normal range, the engine is said to be overheated. And, overheating is likely to damage the engine.

Overheating can be because of multiple causes. We discuss some of the causes here briefly.

1. Low or no coolant
The cooling system in modern cars uses liquid coolants. Water or a solution of water-coolant fluid is used as a coolant. If there is no sufficient amount of coolant or no coolant at all, the radiator fails to get rid of the excess heat. Even the wrong concentration of coolant with water causes engine to overheat.

2. Leaks in cooling system
Cooling system of a car avoids overheating of the engine. Over time, various parts of the cooling system may wear and tear, which might lead to leakage of the coolant. The leakage may happen in any part of the cooling system like hoses, the radiator, water pump, head gasket, freeze plug, the oil cooler in automatic transmission and the heater core. Such leakage may lead to insufficient circulation of the coolant and leads to accumulation of heat and overheating of engine.

3. Bad thermostat
The thermostat controls the temperature of the engine when operating. It controls the flow of coolant from the engine to the radiator. When the thermostat works, the coolant moves from the engine to the radiator. If thermostat gets stuck or if it does not work properly, the coolant will not pass through the radiator and this causes engine to overheat. This process goes on until the operating temperature reaches normal operating temperature.

4. Blockage in passageways of coolant
The coolant has to pass through multiple hoses and connecting piles while circulating across the system to create the necessary cooling effect. However, dirt, rust and sediment from different sources across the system can impair the coolant’s flow. By this, the cooling capacity of the system declines resulting in engine overheating.

5. Radiator problems
Radiator is primarily used to reduce the temperature of coolant. Issues in radiator such as inoperative fan, worn out hoses and/or clogging causes overheating.

The radiator may not work optimally if it loses the coolant because of leaks. Such leaks may happen near the top lip at the neck of the radiator. The caps near the top lip should be fixed properly to prevent leakage and to create vacuum. If the system fails to hold pressure, it will result in overheating of the engine.

In addition, the radiator of your car may become dirty and clogged up because of the accumulation of solid deposits coming from the coolant. This leads to less cooling and heat accumulation.

6. Worn hoses or belts
The hose associated with the cooling system of your car may develop cracks and holes over time. This leads to leakages and impairs the flow of coolant. This can lead to overheating.

Likewise, the belt associated with the water pump functioning optimally leads to optimal flow of the coolant through the cooling system. If the belt slackens, it fails to convey the correct amount of the coolant and it results in engine overheating.

7. Faulty water pumps
Water pump is very crucial for cooling system of car. It generates pressure and propels the coolant across the cooling system. The water pump’s impeller made of steel or aluminum may get corroded because of the suboptimal pH level in the system.

Further, if the shaft of the pump is defective, it can result in lower amount of coolant flow and it results in engine overheating.

Maintenance of a Vehicles Cooling System

Maintenance of a Vehicles Cooling SystemRegular maintenance of a vehicle’s cooling system is important to keep the vehicle running properly and to extend the life and efficiency of the engine. The cooling system includes the components: radiator, water pump, pressure cap, thermostat, fan, hoses, bypass system, heater core and reserve tank. These components optimal function is essential to protect the engine from overheating, damage andbreakdowns. Therefore, it is extremely important that all thecomponents of the cooling system are maintained and replaced when necessary.

Routine checks can help in maintaining the vehicle’s cooling system. Keeping the vehicle on a regular maintenance will ensure that the cooling system works properly. There are some inspections and tests that you can do yourself or you can take help of a mechanic to maintain your vehicle’s cooling system.

Visual inspection of overall cooling system
The first thing you should do is to check all the componentsof the cooling system. Check hoses, belts and the radiator for damage and leaks. In case you notice the engine generates heat faster, there must be something wrong with the cooling mechanism and it needs maintenance.

Check the exterior of the radiator for leaks and corrosion, damaged tubes and clogged fins. Also, inspect head gasket regularly. You can identify blown out head gasket with signs of oily deposits inside the fill neck of radiator

Radiator pressure cap test
The radiator caps are a critical part of the cooling system and are prone to fatigue and wear, and this may lead to loss of pressure control. Therefore, check the radiator pressure cap for the recommended system pressure level atregular intervals.

Check thermostat if it is properly opening and closing
The thermostat controls the amount of coolant being released into the engine. It should open and allow coolant to pass once the engine is adequately heated. Sometimes thermostats can wear and they remain closed. A thermostat that is stuck in the closed position will result in poor circulation of coolant and this leads to overheating of the engine. It is important that the thermostat opens and closes to regulate the engine coolant temperature.

Pressure test to identify external leaks
You also need to check and identify any external leaks and damages to any of the components of the cooling system that include the water pump, radiator, engine coolant passages, heater hoses and heater core. If you suspect there is a problem with any of the components, replace it.

Internal leak test
When you find an internal leak in the cooling system, do an internal leak test by using a pressure tester to check if there is any combustion gas leakage into the cooling system. It is safe to perform a leak check when the vehicle is cold and the engine is switched off.

Engine cooling fan test
The cooling fan keeps the engine away from overheating. If the cooling fan stops working, the coolant will remain hot and this causes the engine to overheat. To make sure the cooling system is operating properly, conduct an enginecooling fan test.

Renting a Car for Road Familiarization

  The advancement of technology made our lifestyle easier than usual. This advancement include: mobile phone innovation (from a huge and heavy device to a light weight hand held mobile phone), energy efficient household items (electric stoves, refrigerators, etc.), telecommunication services (from morse code to high speed internet and ultrafast fiber optics for faster data transmission ), transportation (from a rolling stock to magnetic levitation or bullet train), and now, navigation system (advanced mapping and Global Positioning System).

The emergence of the Global Positioning System (GPS) on handheld and different devices enables us to familiarize maps and easily access to a certain location but internet connection is required. There are a lot of channels now for modern navigation system.

As we grow up, familiarizing the road is a must. Our parents must not guide us to go somewhere and drive us home always. There must be a point where we can stand in our own feet driving and familiarizing the freeway. Though the complex network of highways in the Philippines is somewhat confusing, there are a lot of routes available to go to a certain location that you want to go through.

Driving is a good practice in familiarizing the road and possible route for a certain location. Using some maps on handheld devices comes handy but what if the battery of the device was drained, or the signal for data connection is weak? Or what if, you left your mobile phone? Yes, asking people about directions is a good idea. But what if, you are in a middle of an unknown highway without any houses on the way? Still, there’s a chance of losing the right track.
Thanks to the rental cars who have this pre-installed navigation system directly connected to the GPS. The layout of the city or the place was downloaded to the car’s database so that it can track the car’s exact location including the nearby places and landmarks. It can help new drivers to avoid getting lost during road trips for it has the enhanced mapping technology. The fact that people of this generation loves traveling, knowledge in navigation is an advantage.

While renting this type of car, you can actually memorize the routes available and the possible ways to go to a certain place. Also, you can explore places you never had gone before without any trouble navigating the roads. It’s not just like a virtual map but a combination of a map, a teacher, and locator. This is very ideal for a group of friends who love adventure and exploring different regions for their happiness. Most especially, the youth of this generation is very curious and at the same time, adventurous. Also ideal for families whose passion is traveling, to discover the beautiful hidden paradise. It was the best bonding a family can spend. Traveling in a new place for them to relax, enjoy and escape the stress, the metro is bombarding them every now and then.

Traveling to a place is easier today rather than before. Thanks to the new era of advanced technology and thank you for the inventors and innovators of this new technology. For this matter, traveling is as easy as 1 2 3 and A B C.

There are certain things that the past generation cannot offer today. The advancements in transportation and navigation gave us comfortable yet affordable travel. It can also help travelers to be safe by traveling on a location where it is worry-free. Of course safety is first to assure for our loved ones which includes family and friends.

Things To Check Out Before Stepping Inside an Auto Dealership

   A car might be one of the biggest ticket items you will buy in your life. It can be a nerve-wracking experience–searching for the car you want, finding a reputable dealership, getting the financing you need, negotiating with sales people, and worrying if you’ll get a good deal. Here are five things to consider before stepping onto the car lot:

1. Check Out the Market
Ask yourself what you want in a new vehicle, and list out both your must-haves and your desires. Then, narrow your search. Use popular search automotive resources like,,, and to better research and select the type of vehicle you want. You can filter by model, price, or otheravailable options. These resources will not only help you weed out models with known issues, but will also help you ask the right questions when you visit the dealership.

There is no such thing as too much knowledge when it comes to narrowing the search for your new vehicle purchase. Check Kelley Blue Book at,,,, and even Craigslist to compare prices for cars in your area. Researching the market will give you the edge you need to negotiate once you arrive at the auto dealership.

2. Check Out Your Local Dealerships
But first, you’ll want to decide which dealership will best meet your needs. Hands down, in this situation, word-of-mouth is always paramount. Call on friends and family, especially those who have recently purchased a car. Ask them to share their experiences with you. Find out what dealerships offered great deals, quality vehicles, and good customer service. Be sure to use your better judgment in making your selection. Don’t listen to the uncle, who plays golf on weekends with the dealership owner. Nor the cousin, who raves of a cute salesman but bought a car with a gremlin-sounding malfunctioning engine.

Additionally, you’ll want to check local dealer websites for several reasons. One, you want to know if the model you are looking for is actually in stock. Also, there is much that you can tell about a dealership by reading site reviews and testimonials. You might expect smart businesses to stifle a bit–but, if a dealership has been in business for 25 years or more and only two people can say something nice about the service, you may want to look elsewhere. A well-written and maintained website is another clue. Dealerships with haphazard websites are likely to carry a lackadaisical attitude towards the vehicles they sell and the service they provide.
Finally, look for company transparency. For example, contact information should be easy to find and working. Basic information about inventory should be easily accessible. CarFax history and reports should be readily available as well.

3. Consider Your Budget
Before you can initiate buying the car of your dreams, you need to know exactly what you can afford. Start with a realistic overall price you want to pay for a car. Know exactly what you can afford per month if you’re considering a car loan and how much you can afford for a down payment. Don’t forget to consider the added fees for tags, registration, title, delivery, inspection, sales tax and so on.

Additionally, remember this. You newly purchased car is not necessarily an investment– it’s an expense. So, don’t forget about the continued costs of licensing and inspections, gasoline, insurance premiums, maintenance, and repairs. Budget for everything, and then some. And, stick to your budget.

4. Check Out Financing and Loan Options
Often, car dealerships can offer you the best loan options. But first you’ll need to know what everyone else is offering. Check national interest rates, local banks, and credit unions to find out if dealership financing is the best option for you.

Know your credit score. If your credit score is less than optimal, do what needs to be done to increase your score. Otherwise, you may qualify for a loan with an 8% interest versus the 2.75% national base. Whatever you do, avoid applying for loans all over town. Every time you apply, a credit check or inquiry is run, which puts another ding in your score.

Ok. Kudos to you, if you have all the money you need to purchase your new or used car. But, you might want to keep this to yourself when it’s time to negotiate with a car dealer. If the sales person doesn’t know your limits, he or she cannot push them. Also, wait until the deal has been made before you mention any trade-in. A trade-in and purchase should be two entirely separate negotiations.

5. Check Your Confidence at the Door
So, you’ve done your homework. You know exactly what you want, where to find it, what you can spend, and what to expect in fair financing. You now have purchasing confidence, and you are ready to invest it into your shopping experience. Bringing someone with you who doesn’t have a stake in your purchase might also help. Let that person be the voice of reason and the one to drag you out of there by your ear if needed. Better yet, bring Uncle Joe, the mechanic. A little extra expertise certainly can’t hurt.

Most of all, brace yourself for the “walk-away.” No matter how perfect the car, and no matter how great the offer, prepare to walk out and go home. But, be sure to bring home all the pertinent information and that all questions were answered to your satisfaction. Now, you have time to think about this purchase and talk it over with friends and family. Chances are, if you have done your due diligence, you can walk right back into the dealership the next morning, confident and with a clear conscience, and drive away in your dream machine.
