First off, let’s make one thing straight: the Chery Tiggo 7 Pro Engine Crankcase E4G161009010 isn’t just some plain “metal box”—it’s the “backbone of the engine’s bottom end and the main spot that holds engine oil.” Picture it like a tough, custom-made base that sits right at the bottom of the Tiggo 7 Pro’s E4G16 engine. It holds the engine’s crankshaft (that’s the part that turns the up-and-down motion of the pistons into the spinning power that moves the car), stores the engine oil (super important for keeping parts lubricated), seals up the bottom of the engine so oil doesn’t leak out, and even gives other parts—like the oil pan and oil pump—a place to attach. Without it? Oil would drip everywhere, the crankshaft would be unprotected, and your engine would conk out in no time. This crankcase is made specifically for Chery Tiggo 7 Pro models with the E4G16 engine (the “E4G16” in the part number is a dead giveaway for that)—so always double-check with your car’s VIN or owner’s manual to be sure! It’s built to match the E4G16 engine’s exact size and shape: the little spaces inside fit the crankshaft’s bearings perfectly (no extra friction to wear parts down), the oil passages line up with the oil pump and the rest of the lubrication system (so oil goes exactly where it needs to), and the holes for bolts match the engine block and oil pan perfectly (no drilling or messing around to make it fit). Go for a generic crankcase instead? You’re in for big trouble: it’ll leak oil (which means the engine doesn’t get enough lubrication), the bearing seats might be out of line (wearing out the crankshaft fast), or it’ll be too weak to handle the engine’s vibrations (and crack under pressure). That’s a total disaster for a part that’s basically the engine’s foundation.
This part doesn’t do “optional” work—it’s got 4 key jobs that keep your Tiggo 7 Pro’s E4G16 engine running:
Stores and moves engine oil: It holds all the engine’s oil supply, and has built-in little channels that send oil from the oil pump to the crankshaft’s bearings, piston rings, and other moving parts. This lubrication keeps metal parts from rubbing against each other (which would cause overheating and damage).
Protects the crankshaft: It wraps around the crankshaft and its bearings, keeping dirt, gunk, and moisture away from them—because if those contaminants get in, they’ll ruin the crankshaft quick.
Seals the engine’s bottom: It makes a tight seal with the engine block above it and the oil pan below it. That stops oil from leaking out and keeps dirt from getting into the engine’s inner parts.
Holds key engine parts in place: It has dedicated spots to attach the oil pan, oil pump, and sometimes even the engine’s front or rear seals. This keeps those parts aligned right so they work with the crankshaft like they should.

This E4G161009010 crankcase is only for Chery Tiggo 7 Pro models with the E4G16 engine—wrong fit = engine failure:
This is a foundational engine part; mistakes destroy the engine. Here’s what Chery technicians do:
Prep the engine: They remove the old crankcase (after draining oil and disconnecting the oil pan, oil pump, and crankshaft), then clean the engine block’s bottom surface.
Seal and mount: They apply high-temperature sealant to the gasket grooves, position the new crankcase, and torque bolts to exact specs (over-tightening cracks the alloy; under-tightening causes leaks).
Test for leaks: They refill the engine with oil, start the engine, and check for leaks using pressure tests—ensuring no oil seeps from the crankcase seals.
Check for oil leaks monthly: Look under the car for oil spots (leaks mean failing gaskets—fix immediately to avoid low oil levels).
Replace gaskets during oil pan service: When removing the oil pan (e.g., for oil pump repairs), replace the crankcase-oil pan gasket (old gaskets harden and leak).
Avoid harsh impacts: Don’t drive over large potholes or debris that hit the oil pan—impact can dent the crankcase, blocking oil passages

Exclusive to Chery Tiggo 7 Pro with E4G16 engine (confirm via VIN), this crankcase is the engine’s “bottom backbone & oil hub”: it stores/guides oil to lubricate moving parts (prevents friction/overheating), protects the crankshaft from dirt/moisture, seals the engine bottom to stop oil leaks, and mounts parts like the oil pan/pump.
Made of high-strength aluminum alloy, it has precise bearing seats and oil passages for perfect alignment. Generic crankcases leak, wear the crankshaft, or crack—only the original works. Professional installation is a must; maintain by checking for oil leaks and replacing gaskets when servicing.
