Maserati Service History

Timing chain

No scheduled replacement

CHAIN, no scheduled replacement — called on a direct manufacturer test plus the parent engine's parts evidence, so read the caveat. Test 1 (Maserati's own schedule, THIS engine): the Grecale owner's manual has a separate plan for '2.0 L4 MHEV Engines' whose only belt rows are 'Belt for BSG' and 'Belt for water pump and air conditioning compressor', and it states 'MHEV engines feature two belts. One drives the water pump and the air condition compressor pump; the other belt drives the BSG' (H-S24) — no timing belt, and no timing-belt replacement, anywhere in the plan. Identity: Maserati UK gives the Ghibli Hybrid's engine as L4, 2.0 L, bore 84 mm x stroke 90 mm with a '48V Belt Starter Generator' and '48V battery' (H-S23) — the same 84/90 mm and 1,995 cc as Alfa Romeo's 2.0 T4 (H-S26) — and Top Gear reports it is 'the 2.0-litre four-cylinder turbocharged unit from the Alfa Romeo Giulia' (H-S25). Test 2 (camshaft + opposite kit, on that PARENT engine): the Alfa 2.0 has a 'Camshaft timing chain sprocket' (H-S28), a genuine 'Timing Chain Kit - 2.0L Engine' (H-S29) and an OE timing chain 04893692AA for the '2.0l 280hp i4 di turbo engine' (H-S27), while the specialist's belt catalogue lists only auxiliary belts, tensioners and idlers for the 2.0L (H-S21). CAVEAT: Top Gear also says Maserati 'completely redesigned' the engine and 'only the dimensions and part of the cylinder head have been left untouched' (H-S25), and no Maserati parts source for the 2.0 was reachable (AUTODOC lists neither kit for it, maserati.json F-S11/F-S12), so the chain is inherited from the Alfa unit and confirmed for Maserati only by the absence of any timing belt in Maserati's own schedule. mildHybrid is evidenced by Maserati's '48V' BSG and battery (H-S23). 1,995 cc per AUTODOC's 'MHEV (243 kW / 330 hp / 1995 ccm)' (F-S8) and the 84 x 90 mm bore and stroke (H-S23). Timing only: the schedule's other figures are in km from a manual whose market is not stated (H-S24), so none is carried.

No scheduled replacement

Chain, both tests passed. OPPOSITE-KIT: Jeep Grand Cherokee WK2 3.0 CRD — 13 chain-kit articles, no banner (A2-S41); timing belt 'not available', 2987 CCM (A2-S42). Maserati Ghibli 3.0 D — 13 chain-kit articles (A2-S43); timing belt 'not available', 2987 CCM (A2-S44). CAMSHAFT: PartsTec PTA114-0481 'Driven Units: Camshaft'; SWAG 33 10 1793 with two camshaft gears; iwis (the chain maker) 74641Set 'with camshaft sprocket, with crankshaft gear' (A2-S41, A2-S43). SAME ENGINE ACROSS BADGES: the Jeep and the Ghibli take the identical febi/SWAG/PartsTec part numbers, and the Levante category lists the same febi 173454 / SWAG 33 10 1790 / iwis 74641Set (A2-S45). Maserati Quattroporte Diesel not individually checked. No replacement interval or interference statement found. `years` end is the catalogue's open range, not a sourced UK end date.

No scheduled replacement

CHAIN, no published replacement interval. Camshaft test: Maserati's OE 'TIMING' diagram for the Levante S 3.0 V6 (F-S7) is a primary 'TRANSMISSION CHAIN' from the crank plus two 'TIMING CHAIN's (one per bank), LH/RH hydraulic tensioners, mobile and fixed guide shoes marked '(V6)'; the camshafts sit in separate RH/LH 'CYLINDER HEAD CAMSHAFTS' diagrams in the same group (F-S6). Opposite-kit test: the engine group's only belt diagram is 'AUXILIARY DEVICE BELTS' — no timing belt exists in the OE catalogue (F-S6). 2979 cc for every petrol Ghibli from 330 hp to 430 hp per AUTODOC's type list (F-S8). Read on the 430 hp Levante S; the 330/350 hp tune was not read separately but shares the capacity. The Quattroporte VI V6 (330 and 410 bhp sub-models on the same catalogue) and the 350 hp Levante were not read but share the engine family and capacity. NOT the 2987 cc VM diesel V6 sold in the same cars (F-S16), which is a different engine.

CHAIN, no published replacement interval. Camshaft test: Maserati's OE 'TIMING' diagram for the Quattroporte (2008-2012) 4.2 (F-S10), the Quattroporte (2003-2007) Auto (F-S32) and the GranTurismo (2007-2010) Auto (F-S9) is a 'TRANSMISSION CHAIN' plus two 'TIMING CHAIN's with guide shoes, fixed guides, 'UPPER FIXED TIMING CHAIN TENSIONER's and hydraulic tighteners; camshafts are in separate RH/LH camshaft diagrams. All three diagrams carry identical part numbers (175286, 193616, 186184, 186185, 222310, 196683). Opposite-kit test: no timing belt anywhere in any of them; the only belt reference is an accessory-drive tensioner pulley on the front cover. Only the 2008-2012 sub-model is labelled '4.2' in the catalogue; the other two are tied to it by the identical drive parts. The 4200 GT/Spyder/Coupé (pre-2007) were not checked and are left unmatched. 4244 cc is the DVLA figure supplied with the task. NOTE: the 4.7 (S/Sport/MC) versions are a different capacity and were not read.
