The suspension system connects the wheels to the car body, absorbing road shock and maintaining a smooth ride. It consists of shock absorbers, struts (another name for shock absorbers), control arms, springs and ball joints, which makes it complex and laborious to repair, especially in high-end cars with advanced systems such as air suspension.

Damaged suspension affects handling, tire wear and stopping distances, with repair costs ranging from Shs 300,000 to Shs 1.2 million, depending on the type of vehicle, the damaged part and the quality or quality of parts.

Regular inspections help detect wear quickly and avoid costly replacements. To extend suspension life, Kamya advises avoiding potholes and speed bumps at high speeds.

The timing belt, or cam belt, synchronizes the camshaft and crankshaft to keep the engine’s valves and pistons in harmony. Quality timing belts cost around Sh200,000 and replacing them requires dismantling parts of the engine, often as well as (such as) the water pumps. You may need to replace other parts that work with the timing belt, such as tensioners and pulleys, which could cost you an additional Shs200,000 to Shs300,000.

Signs of a worn timing belt may include misfiring, oil leaking, engine clicking, and a check engine light. The timing belt must be replaced at the latest after 100,000 kilometers during the first replacement in order to avoid serious damage to the engine. Kamya suggests that if your car stalls, avoid starting it immediately, as this may indicate a broken belt requiring urgent mechanical attention. Attempts to start an engine with a broken timing belt can cause serious damage to expensive engine parts.

The transmission is essential for changing gears and transferring power to the wheels. Repairs, rebuilds or replacements can range from 2 million shillings to 5 million shillings due to the complexity of the components; gears, clutches, sensors and solenoids.

Advanced transmissions such as continuously variable transmissions (CVT) or dual-clutch transmissions (DCT) in luxury models are even more expensive. Warning signs of a faulty transmission include slow acceleration, whining, and unusual noises in neutral. Routine maintenance and smooth shifting can extend the life of a transmission and reduce repair costs.

Fuel injectors deliver precise amounts of fuel into the engine’s combustion chamber, essential for optimal engine performance. Fuel injectors typically cost around Sh1.2 million, with diesel or high-performance engines costing more.

Damaged or dirty fuel injectors lead to rough idling, reduced power, and increased fuel consumption. Mechanic Paul Kaganzi advises using high-quality, cleaner fuels from reputable stations. These fuels are mixed with fuel system cleaning additives, as they contain additives that prevent deposits in the injectors and ensure efficient fuel combustion and engine protection.

In manual transmission vehicles, the clutch engages and disengages the engine for smooth gear changes. Clutch replacement involves removal of the transmission and costs between Shs200,000 and Shs500,000 (Shs500,000 to Shs700,000 for a complete clutch kit replacement. Signs of a failing clutch include slipping, difficulty when changing gears, squeaks and burning smells.

Kamya recommends careful driving techniques, such as avoiding “driving” (driving with your foot on the clutch) the clutch to prolong its life and reduce the risk of costly repairs.

The catalytic converter reduces harmful emissions, helping vehicles meet environmental standards. Replacements cost between Sh500,000 and Sh700,000, partly because of the precious metals used in its construction.

Signs of a failing converter include reduced acceleration, poor fuel efficiency, and a rotten egg smell. Regular maintenance and the use of high quality parts when replacing are essential to meeting emission standards and lasting performance.

The alternator powers a vehicle’s electrical systems and recharges the battery while driving. Alternators cost around Shs500,000, depending on the vehicle model. Alternator failure can cause battery discharge and loss of electrical power, causing stalls and other problems. Keeping an eye on battery health and electrical performance can help prevent alternator failure.

The engine’s cylinders house the combustion process that powers the vehicle. Cylinder problems are among the most complex and expensive repairs due to the complex components and labor involved.

Repairs can include replacement of pistons, valves and seals or even a complete engine rebuild, especially for high-performance engines such as the Toyota 1KZ, which can cost up to Sh12 million or more. Regular engine checks and oil changes help prevent cylinder damage and extend engine life.

The radiator regulates engine temperature by dissipating excess heat. It costs around Shs200,000 to Shs500,000 depending on the size and make of the vehicle or more, depending on the vehicle. Signs of a failing radiator include rust, leaks and low coolant levels.

A faulty radiator can cause the engine to overheat, leading to serious damage like warped cylinder heads and blown gaskets. Kaganzi advises checking the coolant level regularly and monitoring the dashboard temperature gauge to avoid overheating problems.

Regular maintenance, timely attention to warning signs and conscious driving can help avoid costly repairs. Listening to your car and fixing problems as early as possible will not only save money, but will also ensure your car’s longevity and peak performance.
