Product Overview
Injector sealing washers are small parts with an important job: they establish the specified contact and sealing interface at the injector/nozzle assembly. Reusing crushed, heat-cycled or damaged washers can contribute to leakage, carbon tracking or improper injector seating.
Toyota identifies 23654-64010 as a washer used with an injection-nozzle assembly, while replacement-market cross listings also associate the number with Mitsubishi and Nissan diesel applications. Because washer dimensions and injector-seat designs matter, the old washer/part number should be matched rather than relying on engine family alone.

Before You Order
Confirm the washer diameter, thickness and 23654-64010 reference against your injector setup. Do not stack washers unless the service procedure specifically calls for it, and clean the injector seat before reassembly.
Frequently Asked Questions
Why replace injector washers?
They deform and heat-cycle in service; a fresh washer helps restore the intended injector seating and seal.
Are these only for one engine brand?
The reference appears in Toyota parts data and is cross-listed in replacement markets for several Mitsubishi and Nissan diesels; verify dimensions for your application.
Can an old washer cause carbon buildup around an injector?
A poor seal can allow combustion leakage and carbon tracking, though injector-seat damage or improper torque can cause similar symptoms.
