Parts for your 2013 Toyota Hilux-Exhaust gasket

2013 Toyota HiLux exhaust gasket: fitted, what it does, and how to look after it

Yes, the 2013 Toyota HiLux uses exhaust gaskets. Toyota’s service literature and parts catalogues identify multiple gaskets across the N70-series HiLux exhaust system. The Toyota Repair Manual for HiLux (N70, 2011–2015) specifies replacing the exhaust manifold gasket during manifold or turbo work and fitting new front pipe ring gaskets on reassembly. The Toyota Electronic Parts Catalogue (dealer EPC/Microcat) for 2013 KUN/GGN/TTN variants lists: the cylinder head–to–exhaust manifold gasket, turbocharger inlet/outlet gaskets and washers on 1KD-FTV diesel, and ring/donut and flange gaskets at exhaust pipe joints. These technical sources confirm the part is relevant and fitted to the 2013 HiLux.

On a 2013 HiLux, the exhaust gasket is a small, crushable seal that keeps hot exhaust gases inside the system where they belong. Whether it’s the manifold-to-head gasket, the donut gasket between the front pipe and cat, or the turbo gaskets on the 3.0 D-4D, each one helps maintain backpressure, quietens the note, and prevents fumes sneaking into the cabin. Left to leak, a tired gasket can cause a ticking sound on cold start, soot marks at the joint, a sharp exhaust smell, loss of torque, and even dodgy oxygen sensor readings on petrol models.

As part of regular servicing, it’s smart to give the exhaust a quick once-over. After the ute has cooled, look for black soot tracks around flanges, feel (carefully) for puffing at joints on first start, and listen for that sewing-machine tick that fades as the metal expands. If any joint is disturbed—say, for clutch work, turbo service, or cat replacement—Toyota’s workshop procedures call for new gaskets and, where specified, new nuts and studs. Reusing old crush gaskets usually ends in leaks.

• Always let the system cool fully before spanner time.
• Follow torque specs and tightening sequences from the Toyota Repair Manual to avoid warping the manifold.
• On 1KD-FTV diesels, replace turbo oil/coolant sealing washers along with turbo gaskets.
• Avoid generic goop near sensors—use quality OEM or equivalent gaskets.

There’s no fixed kilometre interval just for exhaust gaskets, but any sign of leakage or any time a joint is apart is the right time to fit new ones. A sealed system keeps the HiLux legal for WOF/roadworthy, protects occupants from fumes, and helps the engine run sweet as.

Popular questions

Which exhaust gaskets does a 2013 HiLux have?
Depending on the engine, it typically has a manifold-to-head gasket, a ring/donut gasket at the front pipe, flat flange gaskets further down the system, and on the 1KD-FTV diesel, turbo inlet/outlet gaskets and sealing washers. The Toyota EPC for KUN26R/GGN25R variants lists these by location, confirming multiple gasket points across the system.

What are the signs of a leaking exhaust gasket on a 2013 HiLux?
A sharp ticking on cold start that quietens when warm, exhaust smell, soot around a joint, a slight drop in low-end pull, and sometimes increased fuel use. Petrol models may log O2 sensor or fuel trim faults if a leak is ahead of the sensor.

Will a leaking exhaust gasket fail a WOF/roadworthy in AU/NZ?
Often, yes. Excessive noise or any exhaust leak that could allow fumes into the cabin can trigger a fail. Fixing the leak with new gaskets and, if needed, hardware brings the ute back into spec and keeps compliance inspectors happy.
