Maintaining Present Vehicle May Make Financial Sense

Although you may want to get rid of your present vehicle in favor of a new car, taking better care of your current set of wheels may make much more sense in the long run-helping you achieve a goal of financial freedom.

"We advise our clients that if they want a 10 percent increase on their investments every year, they need to cut down on their expenses," said Terry Mulcahy, vice president of investments for R.W. Baird.

"A new automobile is, for most people, their second biggest investment next to a home, so a great way to save money and increase financial assets is to hang onto their current vehicle rather than buy a new one every few years. Budgeting for and doing preventative maintenance on your car is one of the best ways to cut your costs and keep your car."

The Car Care Council estimates that more than $60 billion in vehicle maintenance and repair is not performed every year, evidence that there is considerably more that consumers should be doing to protect their automotive investments.

"Whether it's an oil change, replacing brakes or new belts and hoses, that periodic repair bill is a drop in the bucket compared to monthly payments on a new car," said Rich White, executive director of the Car Care Council. "The bottom line is that a properly maintained vehicle is safe, more dependable, more fuel efficient, less polluting and more valuable. The smartest way to get a solid return on investment is to keep your car through what we call the 'Cinderella Era.' It's that period of time after the payoff when your car is still in great shape and needs only modest repairs."

Figures from Runzheimer International, a management consulting firm that measures travel and living costs, confirms the Council's claims. Recent figures from a Runzheimer study show that trading a vehicle every eight years instead of every four can save more than $2,481.75 a year after the payoff. That includes repairs and maintenance, license, registration, taxes and insurance.

Fluid Leaks: Unsafe and Expensive

Strange Liquids Can Mean Pricey Repairs

 

Posted: 2009-06-04 0:0:0

I own a 2004 Chrysler Pacifica with 87,000 miles. There is a green liquid on the floor of my garage and I think it might be anti freeze. Can I add that stop leak stuff to it? Will it work? What happens if I don't fix the leak?

 

 

Based on the color of the fluid it is probably anti freeze leaking from the cooling system. Do NOT put stop leak in the cooling system! Get the vehicle into a shop and have the cooling system pressure-tested for leaks and repair if needed. If you ignore the problem, you could face major engine damage down the road.

 

Questions and concerns about fluid leaks are quite common. It's a topic worthy of more in-depth consideration, since some leaks can result in major damage and costly repairs if they go unattended and/or the solution to the problem is shortsighted.

Sharon's Chrysler Pacifica comes from the factory with a coolant called ethylene glycol, which is green in color. Some carmakers use a long-lasting antifreeze that is orange in color. If your car uses this coolant and you see an orange fluid on the ground, it could be engine coolant, which is also orange.

Can I add that stop leak stuff? Will it work?

Engine coolant stop leak can and does stop small leaks, but it is a shortsighted solution. As the leak grows the stop leak becomes ineffective. Stop leak typically clogs small coolant passageways in heater cores and radiator tubes. I have seen so much stop leak installed in engines that it actually stopped up water jackets (the water passageways around the cylinder walls). Stay away from this product because it can and does cause more trouble than it fixes.

What happens if I don't fix the leak?

Cooling system leaks only get worse with time. The more coolant lost the hotter the engine gets; the hotter the engine gets, the more likely major engine damage will occur. So, fix it: it's cheaper down the road.

Fluid Colors To Watch Out For:

Red Usually power steering or transmission fluid
Carmel Engine oil
Clear A/C condensation
Clear translucent Brake fluid
Black Gear oil

If I see these various fluids leaking on the ground, should I simply add more?

Adding more fluid is okay. The proper level of whatever fluid is leaking should be maintained because a low fluid level typically results in failure of the system if ignored. However, you need to find the cause of the leak and repair it before serious damage is done and you have to face costly repairs or safety issues. For example, if brake fluid is leaking and the system is allowed to drain, then the brakes will not work, putting you at risk of an accident. If the transmission fluid is too low, friction increases which can cause internal failure and permanent damage to the transmission.

If I see a leak, how to I do I find the source?

Typically, a novice cannot track down and repair a vehicular leak. Systems are difficult to get at and present quite a challenge for the DIY'er.

How do professional techs track down fluid leaks?

Pressure testing: During this procedure air is injected into the vehicle's closed cooling system in an effort to force a coolant leak at the weakest point in the system. When a leak springs, you have found its source and can then repair it.

Dye testing: During this procedure the tech adds a small vial of fluorescent dye to the system he/she is testing. For instance, if the engine or transmission is leaking oil, and the leak continues to avoid detection, the dye is installed in the part that is leaking. The part is then cleaned of all leakage and the vehicle is driven for a few days. At this point the tech will shine an ultraviolet light on the part. A bright yellow color will appear in the area where the fluid is leaking. This is a very effective test for tracking down stubborn leaks.

   

Importance of the pH Value in Engine's Coolant

All types of internal combustion engines requires the use of antifreeze, anti-boil or simply a coolant to remove heat from the combustion area.

Whether it is called antifreeze in the colder parts of the world or anti-boil in the tropical regions, the coolant's function is to lower the freezing point for winter operation or raise the boiling point in warm climate.

The most popular choice of coolant worldwide has always been a mixture of ethylene glycol and water, with the ethylene glycol containing selected and specific inhibitors. While coolant is needed to remove heat in all internal combustion engines regardless of the type of fuel used, a regular control of the coolant solution is required to prevent the engine from severe damage.

Frequent engine repair and failure can be traced to improper or non existent engine cooling water treatment. Rust, scale, mineral deposit and deterioration of seals are the result of improper or no treatment in the cooling system.

From the time the coolant is introduced into any type of engine it starts a gradual degradation process into corrosive acids. This degradation is a function of time, temperature and the types of metals used in the engine and components construction. Once the coolant turns acidic all engine metals start to dissolve. The results are leaking water pumps, heater cores and radiators.

With the increasing number of aluminum engines and components the corrosive process is accelerated since the coolant degrades much faster in contact with aluminum than in typical cast iron engines. During the preventive maintenance of any engine, in addition to the freezing point, the pH value of the cooling system should be checked.

Most automotive manufacturers provide in the vehicle manual information about the suggested mileage or time to change the coolant. However it is important, because of the different climate and operative conditions, to measure the pH of the coolant every time the vehicle is at a scheduled service.

Extensive testing has shown that a coolant pH below 8.3 pH is not acceptable for use in engines due to its corrosive nature. The correct pH value should be maintained between 9.5 - 10.0 pH. Below 9.0 pH it is advisable to flush the cooling system and refill with a new coolant solution.

WARNING: Take proper precautions when removing radiator cap and DO NOT remove when the engine is hot. Accurate pH measurement is achieved when the coolant temperature is below 50 oC.

Ask Mike: Recently you recommended that I have the brake fluid flushed in my car. Why would I do this when it seems to brake just fine?

Good question, brake fluid, both DOT 3 and DOT 4 are glycol based and absorb moisture over time. Moisture contamination causes the fluid boiling point to drop (which could lead to fluid boil and brake fade during hard use).

Moisture contamination also contributes to internal corrosion in the calipers, wheel cylinders, and steel brake lines. The reason for replacing fluid periodically is to get rid of contaminated fluid and restore fluid heat and corrosion resistance. Moisture seeps in through microscopic pores in rubber seals and hoses. It also enters every time someone opens the master cylinder reservoir to check the fluid level. Most fluid reservoirs are transparent so level can be checked without having to open the lid.

Brake fluid is so hygroscopic (attracts water) that leaving the lid off a can of fresh brake fluid can ruin it overnight. It will absorb so much moisture from the air that it becomes too badly contaminated to use.

How often should the fluid be replaced? By the time a new car is only 12 months old, its brake fluid contains about 2% water. After 18 months, the water content is approaching 3%, which is enough to lower the boiling temperature by 25%. After several years of service, it is not unusual to find brake fluid containing seven to eight percent water. For this reason, many experts recommend replacing the fluid as a preventative maintenance service every two years or 24,000 miles. At the very least, it should be replaced when brakes are relined or when cylinders or calipers are replaced.

As always, preventative maintenance can lead to lower repairs costs in the future.
