Renault Clio
Smoother-running 16-valve successor to the D7F, but skipping valve clearance checks every 60,000 km invites trouble. Belt snap equals bent valves — no exceptions on timing belt intervals. Past 100,000 km, expect rising oil consumption and the occasional ignition coil failure.
Solid City Car
75 hp in the light Clio II is sufficient for flowing traffic. No sports car, but pleasant to drive.
Engine Weaknesses 5
The D4F is an interference engine with a timing belt. If the belt snaps, valves bend immediately. Especially the 16V variant is affected — the belt change is involved and crankshaft impulse must be precisely secured.
Symptoms: Sudden engine stop without warning, will not restart
In predominantly short-trip use with extended oil change intervals, condensation water accumulates in the oil. The resulting loss of lubrication film can lead to premature crankshaft bearing wear.
Symptoms: Knocking from engine, loss of oil pressure, engine damage
The D4F requires regular valve clearance inspection and adjustment, which is often neglected by workshops. Insufficient clearance causes harsh running and accelerated wear on cams and rocker arms.
Symptoms: Ticking from valvetrain, rough idle, misfires
The electronically controlled throttle body on the D4F tends to foul up from crankcase ventilation oil. Symptoms are hunting idle and occasional stalling. Cleaning or replacement of the throttle body is the usual fix.
Symptoms: Rough idle, engine stalls, fluctuating engine speed
Like all Renault K/D-engines of this generation, the D4F suffers from early failure of the original Sagem ignition coils. The coils are particularly prone to insulation breakdown in humid and hot conditions.
Symptoms: Cylinder misfires, rough running, engine warning light, poor cold start
Vehicle Weaknesses 6
Rust spots on connectors, weak batteries and loose contacts cause electronics problems. More than half of all Clio IIs fail their first vehicle inspection.
Suspension components and wheel bearings wear prematurely. Tie rod ends and control arms are regularly replaced parts, especially at higher mileages.
Rust on the exhaust system is a classic Renault problem. In addition, brake lines and the underbody corrode significantly on older examples.
The rear drum brakes tend to seize after extended periods of inactivity. Brake pads and brake lines also wear faster than average at higher mileages.
Sagem brand ignition coils in the Clio II are systemically weak. Multiple coils fail in quick succession. Known on 1.4 and 1.6-16V engines, typically from 80,000 km.
Water penetrates under the tailgate and into the door frames; the bodywork rusts from the inside. Faulty door seals and the seal under the tailgate encourage moisture ingress.
