Hyundai Service History

Timing chain

No scheduled replacement

Chain-driven camshafts, no scheduled replacement. Two tests applied. (1) CONTROL, inside Hyundai's own documents: the Hyundai UK service cards and the European owner's-manual schedules DO carry explicit timing-belt lines - 'Replace oil pump and timing belts (1.6 U3 only)' and 'Timing belt (2.2R - Product Enhanced TM model only)' on the UK diesel card, and 'Timing belt system (Timing belt, Oil pump belt, Tensioner, Idler)' for the Smartstream D1.6 in the Kona, Tucson and i40 manuals. No timing-belt item of any kind appears against this engine in any of them. (2) Parts catalogues list a timing chain / chain kit against the engine code and no cam-belt kit. Derived from the absence of a scheduled belt rather than from a positive Hyundai statement, so recorded as reported.

Separately, the 48V MHEV cars carry a MILD-HYBRID BELT that IS a service item: first inspection at 15,000 km (10,000 miles) or 12 months, then replace every 105,000 km (Hyundai prints '65,200 miles') or 84 months (S2). It is not a timing drive - do not confuse the two.

CAVEAT on the control test: buycarparts.co.uk serves a 'timing belt kit' page for the same i30 GD 1.6 CRDi vehicle id as its timing-chain page (S20), which is a catalogue mis-mapping - Hyundai's own schedule for that car lists no cam belt at all, while the same publisher's schedule DOES list one for the later Smartstream D1.6. Do not read a single kit listing as decisive on this engine family.

The real belt on this car is the HSG (Hybrid Starter & Generator) belt, which drives the motor-generator, not the camshafts: the IONIQ manual says inspect every 15,000 km (10,000 miles) or 12 months and replace every 105,000 km (70,000 miles) or 48 months (S3); the Hyundai UK card replaces it at 60,000 and 120,000 miles (S11). Take whichever falls first.

Derived from the absence of a scheduled belt rather than from a positive Hyundai statement, so recorded as reported. Strongest control available: the i40 manual's schedule DOES contain a timing-belt line, but it is qualified '(Smartstream D1.6)' - the 1.7 VGT in the SAME table has none. The camshaft test is satisfied on the parts side too: chain kits for U2-D4FD contain two chains plus camshaft gears (the second chain drives the high-pressure fuel pump), which only makes sense if the chain turns the cams.

Timing chain

No scheduled replacement

Chain-driven camshafts, no scheduled replacement - the existing verdict stands, with the two tests now done directly. Manufacturer control: Hyundai's European schedule for the Tucson TLe schedules a timing belt and an oil belt for the Smartstream D1.6 / 1.6 48V MHEV and nothing of the kind for the '2.0 TCI / 2.0 48V MHEV' (1,995 cc, 84x90) in the same table; the 2.0 48V MHEV's only extra belt is a water-pump drive belt inspected with the MHEV belt (G-S4). Opposite-kit test: chain kits catalogued against D4HA, belt categories 'not available' (G-S6, G-S7, G-S10); Sealey and Laser fuel-pump sprocket tools for 'chain drive' 2.0/2.2 CRDi, D4HA, covering ix35 2010-2016 and Tucson 2015-on (G-S13, G-S14). Camshaft test: febi 176293 'Timing Chain Kit for camshaft and injection pump' - 90-link upper 'Timing Chain for camshaft' plus a 72-link injection-pump chain (G-S15). A Gates Smartstream-D1.6 belt kit catalogued against the 2018-on 2.0 48V Kia Sportage twin is a TecDoc mis-link (G-S10, G-S11).

CHAIN, no scheduled replacement, for the 2,199 cc R2.2 (D4HB) in the Santa Fe CM facelift, DM, Grand Santa Fe and pre-facelift TM. The belt job previously carried on this entry (160,000 miles / 96 months) belongs to the facelifted 'Product Enhanced' TM only (G-S1), which is the Smartstream D2.2 - now its own entry. Opposite-kit test: Lymm TCK268 D4HB chain kit '2 Chains, 2 Gears, 4 Guide Rails & 2 Tensioners', fitment 'Hyundai Santa Fe Diesel - 2.2 2199cc 2009-2020', and no belt kit returned for D4HB (G-S12); AUTODOC's D4HB belt categories (Sorento UM and the pre-facelift Santa Fe TM 2018) are title traps listing brake parts, while the chain categories list 20 parts tagged D4HB (G-S8, G-S16); Sealey/Laser 'chain drive' tools list D4HB for Santa Fe 2009-on and Grand Santa Fe (G-S13, G-S14). Camshaft test: 90-link upper 'Timing Chain for camshaft' + 72-link injection-pump chain (febi 176293, G-S15). The pre-facelift TM manual names the engine 'R2.2', 2,199 cc, 85.4x96 (G-S5).

Chain. OPPOSITE-KIT: 99 timing-chain-kit articles for the i800 2.5 CRDi (A2-S31) and 96 for the Sorento I 2.5 CRDi (A2-S35) — the same RIDEX/DOLZ/SNR kits on both, so the same engine. AUTODOC's belt category shows no 'not available' banner, but its ONLY belt for either vehicle is DT Spare Parts 7.54891 (A2-S32, A2-S36), a 152-tooth generic listing shown against ~30 makes with no engine named (A2-S33) — a catalogue artefact, not a second drive. The chain side is further corroborated by a UK chain kit for D4CB/D4CB-L (A2-S34). CAMSHAFT: SNR KDC484.30 contains 'Gear/Sprocket, camshaft' (A2-S31, A2-S35). The kits carry three simplex chains of 80, 90 and 98 links (upper and lower positions) — all chains, so no `secondary` belt. No replacement interval found (the Hyundai UK 'Service Schedule Information' card does not cover the i800 at all). Interference not stated. `years` end is the catalogue's open range (2008-2026 for the i800), not a sourced UK end date.
