If you wrench on Great Wall’s 1.5L GW4B15, you already know the head gasket story: heat cycles, mixed driving, maybe a coolant blip that turns into a Saturday teardown. To be honest, kits live or die on sealing materials and consistency. This one has been popping up in my inbox—distributors, a couple of fleet techs—and, surprisingly, they all say roughly the same thing: it seals first time, stays sealed.
| Part name | Full gasket set for GW4B15 1.5L turbo |
| Head gasket | MLS (3–5 layer stainless, elastomer-coated, beaded fire rings) |
| Seals & O-rings | Viton/NBR mix, oil- and coolant-rated (≈-30°C to 230°C) |
| Typical thickness | ≈0.7–1.0 mm MLS; others per location |
| Testing (sample) | ASTM F36/F37, helium leak ≤1.0×10^-3 mbar·L/s, Shore A 70±5 |
| Service life | Up to 150,000–200,000 km with proper torque & surface prep |
The Full Gasket Set 1000600XEB15 for Great Wall GW4B15 1.5L covers complete overhaul work—head off, timing service, oil pan reseal, intake/exhaust refresh. It’s especially handy on turbo GW4B15 cars that see mixed city/highway heat cycles. Many customers say they like the “all-in-one” factor: fewer parts runs, fewer leaks after the first heat soak.
| Vendor | Pros | Considerations |
|---|---|---|
| Oujia (manufacturer) | MLS stack consistency, ASTM/IATF docs, fair MOQ, 12-month warranty | Lead time 7–20 days depending on batch |
| OEM dealer | Exact spec, dealer network support | Higher price; stock varies |
| Budget aftermarket | Lowest upfront cost | Mixed materials, variable QA, rework risk |
For fleets, Oujia will tweak MLS thickness and bead geometry, add custom laser marks, even pre-apply non-curing sealant on specific covers. I guess that’s overkill for DIY, but for high-mile taxis it’s smart.
Independent shop in Hebei ran three GW4B15 taxis to 90,000 km post-overhaul—no coolant-oil cross, cold-start idle stable. Another customer mentioned fewer re-torque calls after first heat cycle. That tracks with good embossing and consistent coating cure.
Origin: 289 Heping East Road, Chang 'an District, Shijiazhuang City, Hebei Province, China. If you need batch COCs, ask ahead; they usually provide IATF and ISO 9001 cert copies.
Bottom line: the Full Gasket Set 1000600XEB15 for Great Wall GW4B15 1.5L is a balanced pick—industry-grade materials, sensible pricing, and test data that isn’t just brochure fluff.
