Air Conditioning Problem.

3. Other possible parts are such as: Compressor, refrigerant, condenser, expansion valve, evaporator, receiver/dryer…etc.

Alternator recharge problem.

When you feel like your car hardly start, having low electric power, weak horn sound or weak lights, slow wiper in the morning, then your car alternator may having problem. Alternator work as a charger to recharge your car battery when the car run, if something happened to it, the recharge function will fail.

Brake Problem

Some weird sound when pressing brake or feel hardly stop the car. Most common problem is the brake pad has run out. You can simply check on the wheel, the brake pad is look like 2 thin metal (usually 8mm – 12mm depends on the quality and brand) slip inside the brake caliper.

Clutch problem (for manual transmission car)

Feeling too low for the clutch? Or feeling too hard to press the clutch? The clutch system for a common car break down to few parts, from the clutch pedal to the clutch master pump, then to the clutch plate which taped to the engine.

Drive shaft shaking or vibrating problem.

This problem seldom happens to new cars. Beware if you are looking for any impounded cars for sale. These car could be locked or parked in inappropriate place for a long time and causing the drive shaft jam or when a fork lift is use to jack these cars to container for export purpose and etc..

Engine problem.

Engine brake down to several parts. Battery, ignition, fuel system, exhaust system…etc Therefore if something happen to engine we should check according to the sequence. 1 Battery, 2 ignition, 3 fuel system…etc. Other than these easy things, you will have to leave it to professional to check it.

Exhaust smoke badly problem.


Black smoke, white smoke, or blue smoke? A little bit of black smoke is normal, too much of black smoke is abnormal. White smoke is even more unusual, it might due to piston ring problems. Blue smoke could be the burning oil problem where the gasket of the engine could be damaged, or the engine’s valve, or piston seals. Our advices is, leave this to mechanic. Do not ignore the symptom if you are not planning to keep the car for long.

Fuel system problem.

It is frequent happen that the car problem is just without gasoline in the gas tank. Gasoline price history shows the gasoline price has gone up most of the time, possible some driver just under estimate the mileage can go with the fuel in the tank when they judge according to the amount they pay, not the number of litter gasoline that they put.

Gear problem.

Regardless of manual gear, auto gear, or tip-tronics gears. Gear box isn’t an easy car part to sort out what happen to it. Again, this is hardly to diagnose a car problem online, leave it to a mechanic.

High fuel-consumption problem.

This could be due to the petrol leakage for petrol hose, do check each of the petrol host carefully. Another reason could due to engine tuning. Incorrect tuning will cause high fuel-consumption to the car.

Ignition problems.

The security lock that always make user think it is a big problem. Do checks out Car engine won’t start point no 3 to find out the steering lock solution.

Injection problem.

Most of the cars on the road nowadays is running on fuel injection instead of carburetors. The fuel injector point has to be clean up once awhile during the car maintenance or car service. If it has been left out for long, you will experience imperfect fuel mixture or unsmooth fuel to the car while driving it. Dirty injectors will cause lean misfire, hesitation, poor performance, and an increase in hydrocarbon (HC) emissions. Fuel injection cars were introduced in 1980s and most of the car such as Mercedes-Benz, BMW, Honda…etc has been completely replaced carburetors. Do take note of cars under 500 dollars, most of these cars are old car and it possible still running on carburetors system, thus no injection problem for carburetors car.

Lighting problem.

Standard lighting for a stock car is head lamp, rear lamp, signal lamp. Some cars does come with extra fog lamp and sport lights. Lighting problem usually just the bulb or fuse has burned, replace a new one will solve the problem. A more serious problem could be due to the wiring problem.

Manual car driving problem.

Mounting problem.

Engine mounting should not be a problem for all new cars, if it is, it could be due to factory mistake. For old cars, if the mounting worn, you will feel like the car is shaking or trembling while driving the car.
