AISIN TKT-026 Engine Timing Belt Kit with Water Pump - Complete OE Kit

In this review the AISIN TKT-026 timing belt kit is evaluated for owners of compatible Lexus and Toyota V6 models who want a reliable, complete replacement. The bottom line: this kit is best for DIY mechanics and independent shops that prefer OE-matched parts and want to replace the timing belt and water pump at the same time to avoid repeat labor. It combines an AISIN water pump with matching belt, tensioner, pulleys, gasket and instructions so the overhaul is practical and value-oriented.

Key Features

• OE matched components: The kit includes parts from known manufacturers so replacements match factory fit and finish for dependable operation.
• Complete water pump included: AISIN diecast aluminum water pump with premium internals and carbon ceramic seals provides long-term durability for the cooling system.
• Full timing system: Timing belt, tensioner and pulleys are included so the entire timing drive can be renewed in one service, reducing future labor costs.
• Installation convenience: All parts come packed together with a gasket and instructions so the kit is ready to install and reduces the chance of missing components.
• Vehicle compatibility: The kit is specified for select Lexus ES300, ES330, RX330, RX400h and Toyota Camry, Highlander, Sienna and Solara models, simplifying parts selection for these V6 engines.

Who It's For

This kit is designed for owners of the listed Lexus and Toyota models who plan to perform a timing belt service or commission a shop. It particularly suits those who value OE-matched parts and want to avoid paying twice for the same labor by replacing the belt and water pump together.

It is less suitable for vehicles outside the stated compatibility or for buyers who need only a single replacement component; the kit is intended as a full service solution and assumes the installer will handle a timing belt/water pump job.
