Parts for your 2017 Haval H6-Exhaust gasket

2017 Haval H6 exhaust gasket — purpose, care and when to replace

Based on Haval factory literature (2017 H6 Workshop Manual for GW4G15B 1.5T and GW4C20/GW4C20A 2.0T engines), the Haval electronic parts catalogue (EPC/Microcat), and mainstream gasket catalogues from Elring and Victor Reinz, the 2017 Haval H6 is built with exhaust gaskets. These include a multi‑layer steel gasket between the exhaust manifold and cylinder head, and sealing gaskets at the turbocharger and front pipe joints. So yes—an exhaust gasket is relevant and fitted on this model.

On this H6, the exhaust gasket’s job is simple but critical: keep hot exhaust gases sealed inside the system from the cylinder head, through the turbo, and into the front pipe. A good seal protects the engine bay from heat and fumes, keeps the oxygen sensor and catalytic converter readings honest, and helps the turbo spool as it should. Any leak ahead of the turbo or O2 sensor can throw off fuelling, trim power, and even trigger a warning light.

There’s no set replacement interval in the service schedule. Instead, gaskets should be replaced whenever the manifold, turbo, or front pipe is removed, or if there are signs of leakage. Quality replacements are inexpensive insurance compared with reusing a heat‑soaked seal that may not reseal after being disturbed.

Owners and techs should keep an ear and eye out for common clues:

• Ticking or puffing on cold start that fades as it warms
• Sooty marks around the manifold, turbo flanges, or front pipe
• Exhaust smell in the cabin, sluggish boost, or a whistling note under load

When replacing, allow the system to cool fully, soak fasteners with penetrant, and use new nuts/studs where specified. Follow the workshop manual torque and sequence for the manifold and turbo connections, over‑ or under‑torquing can warp flanges or crush a gasket unevenly. Avoid sealants unless the procedure explicitly calls for them—most OE gaskets on the H6 are designed to seal dry.

A quick check during routine servicing goes a long way: inspect heat shields, feel for escaping pulses around joints (carefully, with the engine idling and cool where possible), and verify no mounting brackets are cracked. If a leak is found, it’s best sorted promptly to protect the turbo, sensors, and to keep the vehicle compliant for WOF/roadworthy checks.

Popular questions

Does the 2017 Haval H6 have an exhaust gasket?
Yes. Factory workshop and parts catalogues show a manifold‑to‑head gasket plus sealing gaskets at the turbocharger and front pipe. They’re essential for keeping the exhaust sealed, maintaining boost, and ensuring accurate sensor readings.

What are the symptoms of a blown exhaust gasket on an H6?
Typical signs include a ticking or chuffing noise on cold start, sooty deposits at a flange, exhaust smell near the bonnet, sluggish boost or a whistle under load, and sometimes a fault code if the leak affects oxygen sensor readings.

Is it safe to drive with a leaking exhaust gasket?
It’s not recommended. Hot gases can damage nearby components, fumes can enter the cabin, and leaks pre‑turbo or pre‑sensor can affect performance and emissions. It’s best to book a repair sooner rather than later.
