The pros of drop in bed liners include the ease with which they may be installed and removed. A drop in bed liner will typically come with a rigid and thick body that will give a decent amount of protection to your truck’s bed, reducing the risk of dents and bumps and scratches. They will last a long time and won’t take too much trouble to clean. Additionally, you can mount them underneath the bedrail, or if you choose, above it, to provide more protection. There are also some drop in bed liners made from more flexible materials; physically hold and manipulate a drop in bed liner before buying it if you can.

Cons of drop in bed liners are that some do not fit as well as they should, making them prone to shift about in the bed of your truck. In contrast, a more rigid bed liner may scuff paint on your truck bed. Additionally, they can let in dirt and sand, increasing the likelihood of scratches. Finally, it is possible to gouge or break a drop in bed liner.

The pros of sprayed on bed liners include the fact that they will not shift on your truck bed, as they are designed to stick to the body panels of your truck. As they are considerably thinner than drop in bed liners, they do not offer the same levels of protection, but they do reduce the risks of tiny dents. Additionally, you can apply sprays to any body panel on the truck, which includes floor and interior panels. Furthermore, you can easily clean a sprayed on bed liner and you can also find them in many colors, which is a bonus if your bed liner is primarily designed to be aesthetic. They are typically considered to be sleeker, visually speaking, than drop in bed liners.

The biggest con of a sprayed on bed liner is that you cannot remove it. Additionally, the lack of protection they offer compared to a drop in bed liner is considerable. Furthermore, you may not be able to remove stains such as spilled paint from your sprayed on liner. Additionally, they are typically more difficult to correctly install and have look professional unless you actually have a professional bed liner install one.

The bottom line is that today’s pickup truck bed liner market is saturated with a host of models to choose from. To help you when next you decide to purchase a bed liner, consider questions related to your needs. How do you typically use your pickup truck? How much protection will you require from your bed liner? Enough to protect the truck from a constant barrage of heavy objects in the bed? Or perhaps you only plan to haul the occasional chair or mattress. Or perhaps you aren’t hauling anything, and the bed liner is purely for aesthetics? Shop around, whether online or in person, and keep asking questions. It’s the best way to ensure you get the best bed liner for your pickup truck.

Before we can go over the most common reasons that head gaskets fail, we need to know what a head gasket is and what role it plays in the proper operation of your vehicle. In an internal combustion engine, the head gasket is a gasket that sits between the engine block and the cylinder head. Its primary role is to seal the cylinders from oil or coolant leaking into the cylinders, and to make sure that the engine maintains proper compression. Therefore, its role in you car’s engine is critical to the proper combustion of gasoline. Now that we know what a head gasket does, we can now explore the reasons that they fail. There are numerous reasons for the failure of the head gasket, but some reasons are more prevalent than others.

Poor Installation of the Head Gasket

A likely culprit for the failure of the head gasket is poor installation. The head gasket is held securely to the engine block by its head bolts. If these bolt are not tightened down correctly, then the head gasket will not have the seal that it needs to operate properly. Another thing that should be considered is that the gasket may have been installed with the wrong type of sealant applied to it. It is quite possible that the wrong type of sealant can cause a chemical reaction to occur on the gasket, thus speeding up its deterioration. This is especially true when the head gasket is composed of a composite material such as graphite.

Spark Knocking or Spark Plug Misfires

The functioning of your engine can have a dramatic impact on the head gasket. A primary cause for head gasket failure is a spark plug knock. This is caused when the fuel in the cylinder is ignited too soon by the spark plug. This makes the engine sound like it has a bunch of loose marbles banging on its interior. A spark plug knock is usually caused by a malfunctioning EGR valve, but other factors such as a fuel/air mixture that is too lean can cause this problem as well.

A spark plug misfire, also caused a detonation, occurs when the gasoline in the cylinder is ignited by something other then the spark plug. This condition can occur if there are hot-spots in the chamber that ignite the fuel before the spark plug has a chance to do its job. Usually this condition can be caused by an engine that has too high of a compression, but there are other culprits as well. It can be caused by using cheap gasoline or gasoline that is the wrong octane, by using the wrong type of spark plugs, or the failure of the EGR valve.

Overheating of the Engine

The main reason that a head gasket fails is overheating of the engine. When an engine is allowed to overheat, then the engine block and the head gasket expands. While both the head gasket and the engine is designed to resist some increases in temperature, a rapid increase in temperature can cause the head gasket to fail. This is usually caused by the failure of a thermostat or one of the radiator hoses. Failure to replace one of these inexpensive parts can lead to a repair that cost thousands of dollars.

Timing belts tend to begin breaking down at around 60,000 miles. You will notice the power to your vehicle begin to slow down, the fuel efficiency of your vehicle can be affected as well as your vehicle showing signs of working harder.

How To Change A Timing Belt or Timing Chain
Different vehicles have different patterns for changing a timing belt or timing chain. The best thing to do when you want to change the timing belt is to look over your owner’s manual that is specific for your make and model vehicle. You can also purchase an automobile repair manual that is designed specifically for the needs of your automobile at any automotive repair shop in your local area.

The basics to changing a timing belt on the vehicle however are pretty much uniform. The steps to do this are as follows:

Step 1. Before you can replace the timing belt on any vehicle it is a good idea to let the vehicle sit overnight so that the engine is completely cool and there is a reduced chance of experiencing serious burns from the engine.

Step 2. As it is with most vehicle repairs you must first disconnect any power supply to the vehicle. This means that the battery cables must be removed from the battery terminal and tied back so that there is no risk of them touching the posts or other parts of the vehicle while working.

Step 3. Place blocks in front and behind the wheels of your vehicle so that there is not chance of the vehicle rolling and accidentally causing injuries to you or others who may be around.

You will now need to remove any obstructions that may be in the way of getting to your timing belt. This includes:

Step 4. Make sure that the air intake assembly to your vehicle is completely removed.

Step 5. Locate the pulley that powers the supply to your water pump if this is in the way on your vehicle. You will need to loosen the bolt holding this pulley in place.

Step 6. For some vehicles it may be necessary to do the same for other equipment such as the power steering pump. This will require you to loosen the bolt and remove the belt that is around the pulley. You can then unbolt the power steering pump and move it out of your way.

Step 7. Line up the mark on your crankshaft pulley to the O that is on the timing scale with a large wrench. You can find the timing scale molded on your vehicle engine block.

Step 8. Using the right sized socket you will have to removed the bolts that are holding the timing belt cover on. When you have the bolts removed you can then pull off the timing belt cover.

Step 9. Inspect the timing belt tensioned bearings for any looseness or noise. If these problems exist you will need to replace the timing belt tensioned bearings as well.

Step 10. Locate your camshaft and check to makes sure there are no leaks in the crankshaft or camshaft seals. If you do notice leaking this could be an early sign that there will be premature failure for your new timing belt. It is best to replace these seals now instead of waiting for bigger problems and the chance of having to do all of this work again.

Step 11. For most vehicle makes and models you should now be able to locate the timing belt. Make sure that all timing marks on your belt are properly lined up. Loosen the timing belt tensioned and you will then be able to remove the timing belt very easily. Make sure that the camshaft and crankshaft for your vehicle’s engine are secured and that they do not move while your timing belt is off of your vehicle.

Step 12. Place your new timing belt on the same way that you removed it. Make any tension adjustments to the timing belt as necessary. Inspect the new belt to make sure that it is fitting over the teeth for the timing sprockets correctly. Makes sure that you do not over tighten the belt.

Step 13. When replacing the timing belt cover install a new gasket to seal the cover correctly. Do not use an old gasket as this will not seal properly.

Step 14. If you had to remove any pumps at the beginning of this project you will now have to hook them back up again. This includes the water pump, power steering pump as well as any other accessories that may have gotten in the way at the beginning of this project.

Step 15. Visually inspect all timing marks to make sure that they are still aligned correctly.

Step 16. Reinstall your vehicle’s air intake assembly that was removed in the beginning.

Step 17. Reconnect your vehicle’s battery. Make sure that there is no corrosion around the posts or the battery cables while you are at this step.

Step 18. Turn on your vehicle and look for any problem areas such as leaks that there may be prior to driving your vehicle. Do not hesitate or postpone any repairs that may be needed.

It is not hard to pay attention to these considerations when auto detailers are plying their trade on their own premises. But at a customer’s home or office, such conveniences as effective drainage and high water pressure are typically not easily or readily available. Residential areas are typically not prepared to handle a significant amount of water which is commonly used in auto detailing. In fact, such huge amounts of water drainage may even lead to fines assessed for causing flooding. Water is becoming scarcer and less readily available, so it is better not to overuse more water than is reasonably necessary.

To answer these concerns, machines which possess low flowing capabilities for water streaming are available. In fact there are quite a few of these specially designed portable machines for washing cars. Using these machines eliminates the possibility of overusing precious water resources, or of having far too much water run off. This permits the mobile detailers to finish the job much faster, as well. This is possible because carpet cleaning machines using restricted water flows will permit the vehicle’s interior to dry in only a couple of hours, as contrasted against more traditional vacuum cleaning machines that need as many as twenty-four hours for the car’s interior to dry completely. The car’s upholstery will dry more thoroughly since a smaller quantity of water has been utilized. On top of this, pressure washers which utilize a lower water flow translate to auto detailers not needing to be concerned with significant water run off while they are cleaning the vehicle. A final benefit to these machines lies in the fact that since there will not be an overly powerful water stream emitted, there will not be any extra water output which is capable of harming the surfaces of the vehicles.

Mobile car washing outfits which employ a lesser quantity of water do not necessarily provide a lesser quality cleaning of the vehicles. Such machines depend on different means of eliminating debris and dirt. As an example, carpet cleaners that use lower water flows similarly rely on potent extraction means for loosening up and taking off deep stains. This proves to be a significant advantage over traditional carpet cleaning machines, that employ enormous quantities of water and still leave a significantly wet upholstery when the cleaning is completed. With the resulting interior wet for a longer amount of time, mold is able to occasionally take hold in the wet upholstery. Similarly, pressure washing machines utilize ideal levels of pressure as well as elevated temperatures of steam to blast away dirt while not hurting the surface of the vehicle. Like this, resistant dirt, such as grease or even hardened mud, may be taken off without having to rely too heavily on water.

It is true that a mobile car washing business ought to be extremely convenient for clients. This means that it should not make any problems for them, as well. The utilization of detailing machines which prove to be efficient with the water turns out to be a significant method for providing superior results without wasting any unnecessary amounts of water.

Here is what to look for when shopping for used car extended warranties:

• Time, miles, or both – Just like new car warranties, used car extended warranties expire based on time, mileage, or a combination of the two. In most cases, it is a matter of whichever condition is reached first. Often used card extended warranties come with the promise of coverage for years or months, but an unreasonably low number of miles. Using automobile leases and insurance estimates as a guideline, it would seem reasonable to suggest that the average car owner drives approximately 30 to 35 miles per day on average. Thus, a 1 year used car extended warranty should last between 11,000 and 13,000 miles unless your specific driving needs exceed that of the average car owner.

• What is covered and how much – Just because a used car extended warranty says that it is good for 1 year or 10,000 miles does not mean that everything is covered for 1 year and/or 10,000 miles. In fact, most warranties, including new car warranties, take their nomenclature from the longest portion of their warranty. So a 10 year/100,000 mile warranty does not typically mean that bumper to bumper coverage is available for 10 years and/or 100,000 miles. Instead, it generally means that only one component of the coverage lasts the titular duration, and other coverage ends well before this point. Even items that are covered are not necessarily covered in full. Again, read the fine print on any extended warranty for used cars.

• Deductibles – A deductible is the amount of money that has to be paid by the vehicle owner whenever the vehicle needs covered repairs. Used car extended warranties come with several different types of deductibles, just like new car warranties. There is a major difference in how the deductibles can be calculated with used car warranties, unlike new car warranties. Used car warranties may have deductibles based on either the repair or the visit. This means that if 10 items need repairs in a single visit, an end user might need to pay ten deductibles or one deductible.

• Transfers – Not all used car extended warranties are transferable, and those that are transferable may have certain limitations. For example, some extended used car warranties can only be transferred to a spouse or immediate relative, while others cannot be transferred under any condition. This might play a significant role in the decision making process if the vehicle is likely to be resold before the expiration of the used car extended warranty.

• How is coverage handled? In many cases, used car extended warranties will require owners to spend money out of their own pocket only to be reimbursed later. This can be a serious problem for those who are looking for used car warranties that are meant to be a form of financial risk management. If the owner has to pay the premium for the warranty and the out of pocket expenses, they may be biting off more than they can chew in the financial sense. This could result in a broken vehicle that waits to be repaired, while a job is lost and the children cannot get to school.

• Who is offering the warranty? Try to determine who is offering the used car extended warranty, and understand that they are a business. Budget warranties from no-name companies are probably worth far less than their associated price tag. Bigger name firms that appear on the Standard & Poor’s list tend to be more expensive, but it is easy to determine the quality of the company behind the warranty.
