High quality Oil Pan (Upper Part) A2740101903 for Mercedes‑Benz 274
If you are sourcing reliable engine system spare parts for Mercedes‑Benz premium vehicles, our high‑quality upper oil pan with OE number A2740101903 is an excellent aftermarket option for your business. This upper section of engine oil pan is specially manufactured to fit vehicles equipped with Mercedes‑Benz M274 turbo petrol engine, widely applied for C‑Class W205, E‑Class W213, GLC X253 and other related chassis models. As a key structural component located at the bottom of engine block, it forms the closed oil‑storage chamber together with lower oil pan, holds engine lubricating oil, maintains proper oil volume, supports partial engine assembly load and prevents oil leakage. This product maintains steady market demand and is widely stocked by auto repair garages, engine rebuild specialists and international distributors across Europe, the Middle East, North America and other global automotive aftermarket markets.
The upper oil pan works under severe under‑bonnet operating conditions. It continuously bears high‑temperature engine oil soaking, engine vibration, thermal expansion and contraction stress, as well as impact from road debris during long‑term driving. After prolonged service, worn or inferior upper oil pans will trigger a series of typical failures. Common symptoms include crack generation on pan body, oil seepage at joint sealing surface, oil leakage around bolt holes, insufficient engine oil level and abnormal engine noise caused by insufficient lubrication. If the defective upper oil pan is not replaced in time, continuous engine oil loss will lead to poor lubrication, serious wear of crankshaft and connecting rod components, and even cause catastrophic engine damage, bringing extremely expensive overhaul costs. Low‑quality upper oil pans usually adopt inferior casting material, inaccurate casting dimension and uneven sealing flange surface. They suffer from body cracking, flange deformation and persistent oil seepage under real‑world working conditions. Our A2740101903 upper oil pan is professionally engineered to resolve these common engine faults.
We adopt premium high‑strength cast aluminium material for manufacturing this upper oil pan. Advanced precision casting process guarantees uniform wall thickness and excellent integral rigidity. Strict surface finishing treatment on sealing flange ensures flatness for gasket fitting. Accurate positioning of mounting bolt holes, oil passage ports and sensor installation openings fully follows OE design standards. Reinforced structural ribs effectively disperse vibration stress and improve anti‑deformation performance. Strict component matching technology ensures perfect assembly performance for M274 engines.
Every upper oil pan A2740101903 is manufactured strictly in accordance with OE specifications. Key parameters including overall dimension, flange flatness, bolt‑hole distribution, sealing surface profile and mounting position fully match original standards. It supports direct drop‑in replacement without cutting, grinding or secondary modification during engine maintenance and overhaul work. Professional service technicians can finish replacement efficiently, saving labour costs for repair workshops. After replacing the faulty original unit with our qualified upper oil pan, reliable oil‑storage sealing performance can be restored, engine‑oil leakage troubles eliminated, and stable lubrication circulation of M274 engine can be guaranteed. VIN verification is strongly recommended before installation to confirm proper fitment.
Comprehensive quality control runs through the whole production process. We carry out raw‑material inspection, material hardness testing, dimensional verification, flange flatness detection, pressure‑tightness test and finished‑product appearance inspection. All finished upper oil pans pass strict off‑line inspection to secure consistent and stable quality. We select qualified raw materials and strike a good balance between reliable performance and competitive factory price. Compared with expensive original spare parts, our aftermarket upper oil pan provides cost‑effective maintenance solutions for vehicle owners.
