A: Check your vehicle’s engine code. This bolt set is primarily for 1ZZ-FE and 3ZZ-FE engines. If your original bolt is stamped with 90910-02152 or the discontinued 90910-02134, this replacement will fit . Also confirm the required quantity, as this set includes 10 bolts.

Q3: Are these bolts reusable?

A: No. Toyota cylinder head bolts are torque-to-yield (TTY) fasteners.

Reusing old bolts can lead to inadequate sealing and head gasket failure.
