Car repairs and car servicing in Milton Keynes

Automobile repair for any problem usually goes through five stages:

The technician verifies the complaint. Don't ever skip this step. Here's what can happen. The driver says, "Something is wrong with the brakes. It makes a big clunk when I stop." The technician inspects the brakes, and they are fine. But the real problem is a bad upper ball joint which clunks when the brakes are applied. So the problem is not brakes, like the driver thought, but something which happens when the brakes are applied. Two different things. VERIFY THE COMPLAINT!

Diagnose the problem. The symptoms of the problem have been noticed and verified, so now we need find the cause of the problem. This is the field of Automobile Diagnostics. At our web page, AutomobileDiagnostics.net, we explain how symptoms are the results of "Abnormal Events," caused by "Abnormal States" within the systems of the car car. The task of Automobile Diagnostics is to identify the abnormal states, so they can then be restored to normal. Any problem in the car is actually an abnormal state within the car; and the purpose of all automobile repair is to correct abnormal states and restore the car to its normal state of operation. You can get more information about Diagnosis from the Factory Manual, the Chilton Total Car Care Manual and the ALLDATA "Do-It-Yourself" online service. You can find information about automobile diagnostic tools in the miltonkeynes information directory.

Do whatever it takes to eliminate the Abnormal States which were causing the symptoms. You can get more information about performing the repairs from the Factory Manual, the Chilton Total Car Care Manual and the ALLDATA "Do-It-Yourself" online service. You can find information about automobile repair tools at our website, Tools4Cars.com. It is usually a good idea to correct all abnormal states you may find in the car, even if they don't appear to be related to the problem at hand. If a wire is loose, tighten it; if something is very dirty, clean it off; if something is leaking, fix the leak. It frequently happens that problems simply go away, without ever really being diagnosed, if you fix everything in sight that seems to be abnormal! Then, after everything is working okay, you realize the connection between what you did and the problem which went away!

Make sure that the repairs you have done have solved the problem and eliminated the symptoms.

A General Strategy For Maintaining Your Car

Where I used to work, before retirement, we routinely get 350,000 miles out of the cars in our fleet on the original engines. This is not done by magic, but by good, systematic maintenance and repair. You may not be able to get quite that many miles out of your cars, but you can come pretty close if you follow these rules we observe:

1. Change the oil every four thousand miles, religiously. Use regular oil, not synthetic; buy the highest quality regular oil you can find; 10W30 is fine for most applications in most cars. Whenever you change the oil, always change the oil filter, too. Funny things can happen inside of oil filters, and it's best not to push them too far.

2. Keep all dirt OUT OF THE ENGINE! This means change air filters and fuel filters regularly; avoid driving on dusty roads. Make sure the air intake system has no leaks which could allow unfiltered air to enter.

3. Never ever let the car overheat. If it even comes close to overheating, stop it immediately and get it fixed. Overheating means premature death to all kinds of hoses, seals, and gaskets in your car.

4. Do not hot-rod the car. Drive it normally, exerting normal stresses on the various parts.

5. Set up a regular maintenance schedule with one shop which knows and loves your car. Schedule the maintenance around your 4,000-mile oil changes. That is, while your car is in for its 4,000-mile oil change, do whatever else is scheduled at that time.

Make sure that one of the top technicians inspects your car during the oil change. You want him to take a look at everything and let you know of any abnormalities. A low-skilled oil-change guy is a very bad idea. A wheel could be falling off, and he might not notice it. You want some sharp-eyed technician who can quickly spot anything which seems to be going wrong.

6. It's okay to do some work on your own car, but be realistic about your abilities. Don't get in too far over your head.

7. It's okay to go outside your regular shop for some things which are done more efficiently outside. Most dealers and independent garages are not as efficient with tires, for instance, as a Sears or a Goodyear store might be.

8. In general, replace parts, don't try to repair them. Replacement parts are made in factories, with the efficiencies of mass production. Parts repair is usually done by one person, working at an inflated hourly rate, with very low efficiency.

9. In general, use high-quality remanufactured parts where available, except for engines, where you should go with used engines, where possible. It's very hard to remanufacture an engine properly. The original manufacturer did a better job than the remanufacturer can usually do. Transmissions are a different story, however: we use Ford rebuilt transmissions which come in a box from the factory.

10. Avoid cheap tires and batteries. They are more trouble than they are worth. (Avoid cheap parts in general, for the same reason.) Buy all-season tires and maintenance-free batteries. Keep the terminals clean and dry on your maintenance-free battery. Since no battery acid should be able to reach your terminals, there is no need for any kind of grease or corrosion inhibitor. If you see corrosion, replace the battery: there is a leak.

11. The only real advantage to tire rotation is that it makes all of your tires wear out at the same time. We replace our tires one-at-a-time, as needed. If you find unusual tire wear, fix the underlying problem, which is usually worn front-end parts resulting in bad alignment.

12. Do not let anything squeak for very long. Squeaking means that improper friction is happening somewhere in your car. Find it and fix it.

13. Do not let anything grind for very long. A low-frequency grinding noise means that actual destruction is going on in your car! Find it and fix it.

14. Develop your sense of smell for automotive smells. Gasoline is one smell; exhaust fumes another; burning oil is another; transmission fluid is one smell, motor oil is another; coolant is a sickly sweet smell; brake fluid is another smell; battery acid is another; brakes overheating is one smell; rubber burning is another. These are the main ones. Try to learn them, and pay attention if you suddenly start to smell any of them.

15. Do not drive when a red warning light comes on. The red ones are serious and must not be ignored. Better to stop the car and catch a cab home than to destroy an engine for lack of oil, for instance.

16. The yellow warning lights are not as serious. They do demand your attention, but you don't usually need to interrupt your trip to fix them immediately.

17. Get to know your car and love it. Be aware when anything seems to change for the worse. Pay attention and be aware of your car just as you are aware of your own body. Be able to express your observations in words, so you can accurately tell your shop what you have noticed.

Automobile Diagnostics

automobile diagnostics - the entire field of investigation and testing to determine the presence or absence of problems in an automobile, and if there are problems, to determine their causes and possible solutions.

many successful auto technicians have never actually sat back and thought very much about diagnosis. they have been so busy diagnosing the cars and fixing the problems that they saw no need to spend much time thinking about it. even so, if you spend a little time and get familiar with a few major concepts, i believe you will find that it was time well spent. you will be well rewarded by understanding the "big picture" of automobile diagnostics in a way you may have never thought about before. you will then be able to tackle any kind of diagnostic job with extra confidence. these concepts are nothing more than mental devices we use to understand things. they do not need to conform perfectly with physical reality or with all the possible philosophical niceties. it is good enough for our purposes if they work for us to help us solve our problems. here are the most important of these concepts, as i see them:

1. normal and abnormal states - everything about the car is either in a "normal" state or an "abnormal" state. either the brakes are acting normally or they are not. either the car is starting normally or it is not. either the engine is running normally or it is not. either the oxygen sensor is performing normally or it is not. either the speedometer is working normally or it is not. either the tires are in a normal state or they are not. used in this way, "normal" means acceptable, they way they are supposed to be, okay. "abnormal" means not acceptable, not the way they are supposed to be, not okay. every thing about the car, even down to the tiniest little bolt, can be categorized as either "normal" or "abnormal."the purpose of all automobile repair is to correct abnormal states and restore the car to its normal state of operation.

2. normal and abnormal events - an "event" is when something happens: a spark plug fires, the brakes are applied, a fuel injector opens, a relay closes, the brake caliper squeezes. an event is a change of state, from one condition to another. a "normal event" occurs when something happens just as it is supposed to happen: the headlights come on when the switch is turned on, the engine valves open and close at their proper times. an "abnormal event" is when something happens that is not supposed to happen: the engine quits unexpectedly, the car fails to stop when the brakes are applied, the alternator makes a funny noise. all automotive complaints can be described and understood in terms of abnormal events: some things are happening which are not supposed to happen, and the driver has noticed them. if all the states are normal, all the events will then be normal, and there will be no complaints. problems solved!

3. upstream and downstream - any automotive process can be understood as a sequence of related events and states happening over time within a context. the context is all of the other events and states which exist at that moment in time. the earlier events and states in a process are considered to be "upstream" from the later events and states, which are considered to be "downstream." any abnormal event or state downstream must have been caused by abnormal event(s) or state(s) upstream from it.

4. the normal processes - a normal process is one in which all events and states are normal. it is necessary to understand the normal processes in a car in order to recognize and understand the abnormal events and states which may occur and need to be corrected.

5. levels of abstraction - processes can be understood and described in different levels of abstraction. a high level of abstraction is one in which the process is summarized, with very few details. here is a process description in a very high level of abstraction: "you push on the brake pedal and the car slows down and stops." here is another one: "you turn the key to the right, and the engine starts." a low-level description of the very same processes might take five thousand words, providing much detail about the operation of the various parts of the automotive systems.

6. causation - in automotive diagnostics, we are looking for the causes of abnormal automotive events, in order to correct them and bring all processes back to normal operation. so we do not need to address the entire philosophical question of "causation," but only those parts of it which we need in order to understand the causes of abnormal automotive events. and this is the main thing we need to know: abnormal states cause abnormal events. if we correct the abnormal states which are causing our abnormal events, we have solved the problems.
