Description
The PAI Industries 390079EX is a remanufactured (exchange) fuel injector assembly for Caterpillar C15 and C18 diesel engines. It replaces Caterpillar injectors 253-0616 and 244-7716, as well as the Cat Reman exchange number 10R-3265. Each exchange injector is remanufactured to restore OEM flow, pressure, and spray-pattern performance at a meaningful saving over a dealer reman unit. A core charge applies and is refunded when your rebuildable core is returned.
Symptoms of a Failing Fuel Injector
- Rough or unstable idle and cylinder misfires
- Low power under load and poor throttle response
- White or black exhaust smoke
- Audible fuel knock
- Falling fuel economy
- Hard starting, particularly when the engine is warm
