Case followed in Goiânia shows how a 2020/2021 Renault Kwid, with 127 thousand kilometers, went from persistent failures, injection light on, and previous repair attempts to a complete engine replacement that cost R$ 16,420.

R$ 16,420 was the final cost of corrective maintenance for a 2020/2021 Renault Kwid with 127 thousand kilometers, a case where carbon fiber weighed nothing against severe engine failures.

In the record of the Canal Carros with Tiago, the car arrived at the workshop with irregular operation, difficulty starting, injection light on, and a history of visits to other repairers, after changing the probe and fuel pump.

Diagnosis exposed problem beyond the replaced parts

The disassembly showed that the defect was in the engine assembly, not just the peripheral components. The cylinder head was part of the initial investigation, but the opening revealed a broader scenario of wear, dirt, and compromised maintenance.

Carbon fiber does not solve lack of basic maintenance

The opening of the valve cover revealed dark sludge in the engine. The evaluation associated the internal state with overdue oil changes, incorrect lubricant use, or idle periods, although the case shown involved high mileage.

The oil pump strainer was quite clogged. In the oil pan, the amount of sludge was notable. Corrosion in the cylinder was also indicated, leading to the conclusion that reboring would not be worthwhile.

The absence of the thermostat valve and the use of glue on components reinforced that the car had already undergone previous interventions. In this context, the replacement of isolated parts was not enough to restore regular operation.

New engine raised the Kwid’s bill

The customer bought a new engine at the dealership for R$ 11,500. The assembly came with valves, spark plugs, knock sensor, oil sensor, water pump, flywheel, thermostat valve bracket, and oil filter.

The new clutch, original mount, correctly specified oil, additive, original probe, throttle body cleaning, additional parts, and labor completed the service. The workshop reported an additional R$ 4,920, bringing the total bill to R$ 16,420.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.
