LP gas is a camper's best friend. It provides us with warmth on a chilly day, hot water to shower with, cold food in the fridge and the capability to cook on the road the same way you do when you're at home. When we need it it's there, instantly providing us with all of the amenities and creature comforts we are accustomed to. We don't really even think about it, it's taken for granted that when you push that button, almost like magic it responds to your demands.

But what is LP gas? Should we be afraid of it, or just continue to take it for granted? Liquid propane, more commonly known as LP gas gets its name because it is stored in a liquid state. When LP gas is manufactured it is compressed and stored under pressure, which causes it to liquefy. When the pressure is released the liquid turns back into a vapor. LP gas is odorless, colorless and tasteless. To assist you in detecting a leak an odorant is added to it when it is manufactured. If you are not familiar with the odor of LP gas, the next time you go to a qualified fill station ask the attendant to let you smell it. Most people describe the smell as being similar to rotten eggs, or as having a garlic odor.

We'll get back to more characteristics of LP gas in a minute, but first let's address the second question. Should you be afraid of it? You should respect LP gas, because all gases have dangerous characteristics. If you check for gas leaks using an open flame you are certain to be in danger. I guess what I am trying to say is that LP gas is one of the safest of petroleum products if it is handled properly. More times than not, when there is an accident involving LP gas it is due to negligence or improper handling.

LP gas is portable, safe when handled properly and it's very efficient, so it only makes sense that it is used in RVs. I mentioned a moment ago that LP gas is compressed in a liquid state and stored in containers. Because of the amount of pressure involved the containers are manufactured under very stringent codes. There are two basic types of containers, Department of Transportation (DOT), and American Society of Mechanical Engineers (ASME). The DOT containers, more commonly called cylinders are the upright type that you see on Pop Up's, travel trailers, or your BBQ grill. The ASME cylinders are referred to as tanks and are mounted horizontally like the type you would see on a motor home.

Regardless of the type, all LP gas containers are only filled to 80 percent of their capacity to allow for expansion when the temperature around the container rises. LP gas cylinders are equipped with Overfill Protection Devices or OPD valves to prevent them from being overfilled.

LP gas can be measured in weight or in gallons. You may have heard somebody say that the gas cylinders on their travel trailer are 30 lb. cylinders, or they may say their cylinders hold 7 gallons apiece. One gallon of LP gas weighs 4.26 pounds. The typical BBQ grill uses a 20 lb. cylinder, so at 80 percent full it would hold 3.75 gallons of LP gas.

When you open the valve to the gas cylinder the liquid gas turns back into a vapor and goes into a two stage regulator. In the first stage the pressure coming out of the cylinder is reduced significantly close to the proper burning range for the LP gas appliances. The second stage reduces it to the required 11 inches of water column needed to run the appliances properly.

There is also an LP gas leak detector inside the RV that will set off an alarm to alert you if there is a gas leak. It's normally located close to floor level because LP gas is heavier than air and it will settle towards the floor. If you ever smell LP gas when you're camping, or if the LP gas leak detector goes off you could have a leak somewhere in the system. If this happens you should:

*Extinguish any open flames, pilot lights and do not smoke, or touch electrical switches.

*Evacuate the RV and turn off the main gas supply valve.

Leave the door open and do not return to the area until the odor clears.

*Have the system checked out by a qualified technician before using it again.

*False alarms can be caused by hair spray, perfume, cleaning solvents and low battery voltage.

Let's take a moment and discuss some dos and don'ts concerning LP gas.

*Do remember to turn the main gas supply on when you're ready to use a gas appliance.

*Do have the system checked if you suspect a leak, disturb the gas system, or at least once annually.

*Do take the proper steps to safely transport, store and use LP gas cylinders.

*Do review all cautions and warnings on the LP gas system and appliances in your owner's manual.

*Do not use an open flame to check for leaks.

*Do not use the range burners or oven as a source of heat; it is not vented outside and depleted oxygen can cause asphyxiation.

*Do not go to a gas station to refuel unless you extinguish any open flames and, or pilot lights and turn LP gas appliances off.

*Do not transport LP gas cylinders inside a vehicle.

*Do not be afraid of LP gas, but do respect it and handle it properly.

Happy Camping!

Jobs Available with an Automotive School Degree

Many who are interested in getting an education from an automotive school are unsure about the job security an automotive career can offer. There are a wide variety of jobs available to graduates of automotive school programs. Because car ownership and usage has only expanded in the past few decades, and continues to increase dramatically by the year, anyone with an automotive background is virtually assured a job.

Oil and lube technicians
Cars require a lot of regular maintenance, such as oil changes, a service that each car owner will need done every three months or less. As a result, there are many oil and lube shops that provide these services. The tight time schedule many of these shops adhere to ensures plenty of jobs for technicians who have the knowledge and experience to perform these tasks quickly and easily. Any graduate of an automotive school will be able to easily defeat the competition for these positions.

Automotive technicians
Automotive technicians are often hired by shops that provide more services than oil changes, air filter replacements, and other simple maintenance. Automotive technicians may be hired to mount and dismount tires, balance wheels, change brake pads, and perform tune ups, in addition to changing the fluids and filters in cars.

Mechanics
Mechanics tend to have more responsibilities than technicians, therefore requiring more education and experience. Mechanics may do all of the jobs often assigned to automotive technicians, but they also perform more complex repairs. Important components, such as shocks and struts, drive shafts, alternators, starters, etc. are usually replaced by mechanics. Additionally, more complex or critical maintenance tasks, such as readjusting the valve clearance in an engine, replacing the timing belt, and performing other engine work, are done by mechanics. Any good automotive school will provide the education and hands-on training necessary to perform maintenance of this caliber.

Master mechanics
The title of master mechanic is one any automotive school graduate would be proud to hold. Many schools include more advanced degree programs, providing the education and hands-on training necessary to be a master mechanic. Master mechanics can find jobs at almost any high quality automotive shop, garage, or dealership maintenance department. Naturally, the pay for a master mechanic position is considerably higher than that of an automotive technician or mechanic.

Auto body and paint specialists
Most have noticed the increased number of accidents you see on the road today. Someone has to repair all of that damage. Auto body and paint specialists are therefore in quite high demand. Auto body technicians are responsible for replacing exterior body parts and repairing the damage caused in accidents. Paint technicians paint the car once the damage has been repaired and the necessary parts replaced.

Parts sales people
There are, of course, the brave car owners who attempt to keep up on their cars' maintenance and repairs on their own. Therefore, there are also many parts stores and dealership parts departments to keep up with this demand. Graduates of automotive school programs make great additions to parts sales teams, because they have the ability to do more than just look up a part number and grab the part off the shelf: they can discuss problems with the customers, try to help diagnose, and tackle the problems that occur when parts catalogues are wrong and computers fail. Most part sales departments like to have at least one very knowledgeable person on their team.

Automotive sales people
Just as with parts sales, there isn't a better person to sell a car than someone who knows a lot about them. If you have an education from a good automotive school and you have a knack for selling just about anything, you will always be guaranteed a job at any car dealership. Dealerships love to have knowledgeable, smooth-talking salespeople on their team. A person to represent the dealership's interests and also knows cars inside and out.

Automotive manufacturing
There are more and more cars on the road every year. Although there are many unskilled positions in automotive manufacturing, there are also many openings for people who know a lot about cars. An automotive degree will give you the knowledge and experience necessary to quickly climb the ladders in automotive manufacturing.

Automotive design and engineering
Cars change more than their looks each year. Technology is constantly making them better, faster, and more reliable. One of the most prestigious jobs in the automotive world is to be one of the concept designers or engineers who make those new cars possible. Designers and engineers must have a solid understanding of automotive theory, as well as engineering practices. This advanced education begins at a good automotive school.

These are only a few of the many jobs available to automotive school graduates. The automotive industry is a demanding field that includes many different positions, from the creation and sales of brand new cars, to the upkeep and repair of cars that are currently in use. An automotive degree will ensure that you always have a place in this exciting and constantly expanding industry.

96 Dodge Neon-DodgeMan plz reply?

Ok my 96 Neon is at it again the left front (driver) Caliper is hanging once again now here is a list of what i replaced.
(If there was two they both got replaced)
Master Cylinder
Calipers
Brake lines (Rubber)
Proportioning Valves
Rotors (Front)
Brakes (all around)
Caliper slide pins
Everything was cleaned as well.
Tonight the left front started to drag or hangup again its around 23 degrees so im not in the mood to pull the wheel and look at things nor do i have the time atm.

let me ask you this, did you flush the lines out real good because dirty fluid or a kink in the line will cause it not to release the pressure as it should,and another thing i have found that causes that too happen is if you use synthetic brake fluid in them, some of the cars wont accept this for some reason,and a lot of shops are recommending that you use ,but my results with it have been pretty negative especially in colder weather conditions,but what it sounds like that's happening is its not releasing the pressure on the caliper,try loosening the bleeder when you get a chance and see if this releases the caliper on it if it does you may have to go over it and re-bleed the system again,good luck,let me know how it turns out and i,ll help you with it,
