Benefits and disadvantages of the H4Dt engine
Benefits
- Economy: Low fuel consumption (only 3.8 liters on the highway for Renault Clio with MKPP) makes this engine attractive for urban and suburban driving.
- Reliability: Simple construction and the use of antifriction coatings on rubbing surfaces increase engine life.
- Power and traction: Despite its small displacement, the engine is able to generate sufficient thrust thanks to the turbocharger and 160 Nm of torque.
Disadvantages and problems
- Drag failures: In the first year of operation, owners complained of traction failures, but the problem was fixed after the ECU firmware update in 2019.
- Valve cover leaks: Early versions of the engine often had oil leaks from under the valve covers.
- A modest life of the timing chain: The timing chain has a life of 100-150 thousand kilometers, after which it requires replacement. In parallel with this may occur cracking of the phase adjuster on the intake shaft.
- Valve adjustment: The absence of hydrocompensators means the need for manual adjustment of valve clearances every 60,000 km.
- Oil consumption: Some owners have reported increased oil consumption after 50,000 km, although these are few and may be due to a failure to follow engine recommendations.
Reliability and maintainability
Reliability
The H4Dt engine is considered reliable, if you follow the service regulations. According to experts and owners, with quality maintenance, the engine is able to work up to 350,000 km without serious breakdowns. The use of modern technologies, such as antifriction coating of rubbing parts, helps to increase the engine life.
Remountability
Despite the complexity of modern engines, the H4Dt has a lined cylinder block, which makes it easy to repair. Major problems, such as worn timing chain or phasoregulators, are solved by standard component replacement. Otherwise, the engine is quite repairable and can be restored to running condition if necessary.
How good is the H4Dt 1.0 engine?
The Renault H4Dt 1.0 TCe 100 engine is a modern turbo engine that is well suited to compact cars and crossovers.
