Product Details

Continental Pro Series TB303LK1 is engineered for vehicles that require coordinated replacement of the timing belt, water pump, and related tensioning components during scheduled service. The curvilinear belt profile is specified for the listed applications, and the metal-impeller pump supports cooling system service at the same time as the timing drive. This part number is used across multiple fitments, including the Isuzu Rodeo, Honda Passport, and Isuzu Trooper, as well as select Acura and Isuzu models.

Pro Series identifies Continental’s service-focused product line for timing system repairs where OE-quality fit and component matching matter. For buyers searching for an Isuzu Rodeo timing belt kit with water pump, Honda Passport timing belt kit, or Continental TB303LK1 replacement, this kit addresses the core wear items commonly serviced together on interference engines.

What It Helps Address

• Timing belt wear, cracking, or age-related deterioration
• Water pump leakage or cooling system service during timing repair
• Noise or rough operation from worn tensioning components
• Preventive maintenance on interference-engine timing systems
• Service replacement for vehicles due at the timing belt interval

Installation Notes

Verify engine code and application details before installation, especially on 1998-2004 Isuzu Rodeo, 1998-2002 Honda Passport, and 1998-2002 Isuzu Trooper models. This kit does not include seals. Follow factory timing procedures, align all timing marks during assembly, and inspect related cooling system components before reassembly. Because this is an interference-engine application, correct timing setup is critical.
