Fel-Pro Cylinder Head Bolt Set ES 72434 for Toyota/Lexus/Pontiac Vibe — OEM-fit TTY Replacement, Engine Clamp Load Restored

Fel-Pro ES 72434 is a complete engine cylinder head bolt set engineered to match original equipment fit and performance for select Toyota, Lexus and Pontiac Vibe engines.

This bolt set replaces torque-to-yield and other factory head fasteners with application-specific hardware that meets or exceeds OEM specifications. Designed and validated to restore clamp load and alignment after a head service, these bolts eliminate the uncertainty of reusing single-use fasteners and reduce the chance of improper torque or fit during engine assembly. Every kit is built to Fel-Pro’s standards for fit, form and function so mechanics and home builders can proceed with confidence.

Which vehicles and engines work with the ES 72434 bolt set?

ES 72434 fits a wide range of Toyota and Lexus models across multiple years and also covers the 2009–2010 Pontiac Vibe. Compatibility spans Corolla, Prius, Prius V, Prius Plug-In, Matrix, CT200h and Corolla iM in specific model years. Always verify your engine code and model year before ordering to avoid fitment mistakes.

• 2009–2010 Pontiac Vibe
• 2009–2020 Toyota Corolla and 2017–2018 Corolla iM
• 2009–2014 Toyota Matrix
• 2010–2020 Toyota Prius, 2012–2018 Prius V, 2012–2015 Prius Plug-In
• 2011–2017 Lexus CT200h

Why should I replace torque-to-yield (TTY) head bolts instead of reusing them?

Many modern head bolts are designed as torque-to-yield fasteners that permanently stretch when torqued to specification. Reusing TTY bolts risks inconsistent clamp force, which can lead to head gasket leaks or uneven sealing surfaces. Replacing with a matched Fel-Pro kit restores intended clamping and reduces the risk associated with reused single-use bolts.

• TTY bolts stretch—replacement ensures correct clamp load
• Prevents sealing failures caused by diminished bolt elasticity
• Fel-Pro hardware is validated for fit, form and function

How does this bolt set help during a cylinder head service?

Using the correct head bolts simplifies reassembly and assures the torque sequence and final clamping mirror factory conditions. The ES 72434 set is manufactured to meet or exceed OEM mechanical properties, helping technicians achieve reliable sealing and alignment after head machining or gasket replacement. That consistency reduces callbacks and supports long-term engine durability when paired with proper installation practice.

• OEM-grade materials and heat treatment for predictable torque values
• Validated sizing and thread engagement for precise fit
• Reduces rework by matching original assembly specifications

What should I check before buying this Fel-Pro head bolt kit?

Confirm vehicle year, make, model, engine type and trim to ensure compatibility. If purchasing through marketplaces, use the vehicle fitment tool or the "Confirmed Fit" indicator and read any additional notes. Also ensure you have the correct torque specs and sequence for your engine and consider replacing related fasteners or seals as needed during the repair.

• Verify exact vehicle year, engine and trim before ordering
• Check marketplace "Confirmed Fit" and read qualifier notes if present
• Have factory torque specs and sequence available for installation

Who is this for: The Fel-Pro ES 72434 cylinder head bolt set is intended for professional technicians and knowledgeable DIYers performing cylinder head removal, resurfacing or head gasket replacement on compatible Toyota, Lexus and Pontiac Vibe models. It suits anyone who needs reliable, OE-quality replacement fasteners—especially where torque-to-yield bolts were used originally and single-use fasteners must be replaced to restore proper clamping and sealing.
