There are lots of problems that can arise with cars today that is why there are so many help sites and books being released today with the aim of helping you discover exactly what the problem is to start with then what has to be done to rectify the problem. Below are some common problems people can have with their cars and maybe not know exactly what's causing the problem along with the cause of the problem and what needs to be done about it.

When driving my car the steering seems to shake slightly and I don't know what the problem is, what could it be?

Many people have this problem with their car but a lot of the time it can just be due to general wear and tear of the brake rotor causing it to warp, or even the fact the brake pads are that worn out its causing the metal from the pads to rub against metal on the disk brake rotor making cuts in the metal on the rotor surface.
To solve this you first need to discover which it is so if you remove the car wheel then the calliper you will be able to get a look at the brake pads if they are in ok condition then you can rule out them as the cause. However, if this is the cause then you would simply have to replace the brake pads following instructions to help you do so then take your car to a garage to have the rotor "trued", this is a process where mechanics use a piece of equipment to smooth the surface of the rotor removing any fault from it. If it is not the brake pads you would simply have to have the car taken to a garage to have the rotor surface "trued" and that should erase the problem.

My car over heats easily when I'm driving at high speeds for a period of time, what could be wrong with it?

With a situation like this you firstly need to check the levels of anti-freeze/water mixture in the radiator, when you have opened the radiator cap you should be able to actually see the level of water in the radiator, if not then there's not enough in it. Then you check for any leaks in the system such as fluid leaking onto the floor etc if you do find a leak you should then have the car taken to a garage to see where exactly it is coming from in the system. When you have ruled out a leak or lack of coolant and water as the problem then it may well be to do with the airflow and flow of coolant, for example if there is a kink in one of the radiator hoses it will restrict the flow of coolant at high speeds and due to it needing more going at high speeds it can cause the engine to over heat. In order to solve the problem either removing the radiator and having it taken apart and thoroughly cleaned or completely replacing it all together because once a radiator is blocked its hard to unblock.

Many problems that occur with cars very often have simple solutions but to prevent the problems happening in the first place simple maintenance of the vehicle usually helps. For example the problem with the radiator problem above, if it was due to a blocked radiator, if the maintenance work of ensuring its filters and water/coolant mixture was clean and they flushed the radiator out occasionally the problem may never had occurred. If you spend the time finding out maintenance methods then you are likely to face less problems when it comes to having your vehicles serviced there fore saving you money in the long run.
