DEXWAL MOBIDEX timing belt (07-115) synchronises the crankshaft and camshaft with tooth-pitch accuracy measured in hundredths of a millimetre — preventing valve-to-piston contact that would destroy the engine if the belt skips or snaps. Tooth profile, pitch, and width are specified for the camshaft drive on CITROËN, DACIA, PEUGEOT engines; always replace the tensioner and idler pulleys simultaneously to prevent premature failure. OE cross-references: 00 000 829 19, 0000082919, 00 000 829 54, 0000082954 and 106 more. DEXWAL MOBIDEX timing belts are tested to OEM replacement intervals and carry a service-life certificate verifying the compound meets the manufacturer's durability specification. Timing belt replacement intervals vary by manufacturer — typically every 40,000–100,000 miles or 4–6 years, whichever comes first — and must be followed strictly because a snapped belt on an interference engine causes catastrophic valve and piston damage. There are rarely visible warning signs before a timing belt fails; some belts may exhibit surface cracking, fraying, or a glazed appearance, but many break without warning — this is why interval-based replacement is essential. Timing belt replacement is an advanced DIY job requiring careful crankshaft and camshaft alignment, a torque wrench, and engine-specific locking tools — budget 3–5 hours and consult a workshop manual for your exact engine code. When replacing the timing belt, always fit a new tensioner, idler pulley, and water pump (if belt-driven) at the same time — these components have the same service life, and a failed tensioner will destroy the new belt. Investing in a quality timing belt kit now prevents the most expensive engine failure a vehicle can suffer — a belt-related engine rebuild typically costs 10–20 times the price of the belt kit itself.
