Fel‑Pro Engine Cylinder Head Bolt Set ES 72390 — GM TTY Replacement for Cadillac & Chevrolet (2009–2017)

Fel‑Pro ES 72390 is a complete engine cylinder head bolt set engineered to match original equipment fit, form and torque specifications for select GM Cadillac and Chevrolet vehicles.

When replacing cylinder head bolts, using the correct torque‑to‑yield (TTY) replacement set matters for engine sealing and long‑term reliability. The Fel‑Pro ES 72390 kit supplies new, application‑specific head bolts manufactured to meet or exceed OEM standards, eliminating the hazards that come with reusing stretched or weakened fasteners. This product is validated for fit and function on multiple Cadillac and Chevrolet models so you get a direct replacement designed for the original engine hardware.

Which vehicles and engines does this bolt set fit?

ES 72390 was developed for a range of late‑model GM vehicles. It covers various Cadillac Escalade, Escalade ESV, Escalade EXT, CTS, and several Chevrolet models, including Suburban, Express 4500, and SS, across model years listed in the compatibility data.

• Fits 2009–2014 Cadillac Escalade ESV and 2009–2014 Escalade variations
• Compatible with 2009–2013 Escalade EXT and 2009–2015 Cadillac CTS

• Always verify engine, year, trim and any qualifier notes with vehicle fit checker before ordering

How does this set improve repair reliability compared to reusing old head bolts?

Torque‑to‑yield (TTY) bolts are designed to stretch slightly when torqued to specification. Reusing them can result in improper clamping pressure, leaks or uneven torque distribution; installing a new Fel‑Pro set restores correct clamping characteristics and reduces the risk of head gasket or sealing issues.

• New bolts provide consistent stretch characteristics for accurate torque readings
• Prevents unpredictable clamping force caused by previously stretched fasteners
• Helps maintain head gasket sealing integrity and engine performance
• Manufactured to meet or exceed original equipment specifications

What quality checks and design features does Fel‑Pro include?

Fel‑Pro validates each kit for fit, form and function to ensure it matches the application‑specific design requirements of the original fasteners. The company uses material and manufacturing processes intended to meet or surpass OE standards so the bolts perform reliably under engine operating conditions.

• Application‑specific design for precise OEM replacement fit
• Material and heat‑treat processes to maintain required yield characteristics
• Validation testing for fit, form and function before release
• Backed by Fel‑Pro quality standards trusted by professionals

What should I check before buying and installing these bolts?

Confirm vehicle compatibility and any special installation notes prior to purchase. Use the seller’s fitment tool and review any qualifier icons or notes so you select the part that matches your engine, model year and trim. Follow OEM torque sequence and replacement procedures when installing to ensure correct results.

• Enter year, make, model, engine and trim into the fitment checker
• Look for additional qualifier notes if an information icon appears
• Replace all TTY head bolts—do not reuse old bolts
• Follow vehicle manufacturer torque specs and tightening sequence during installation

Who is this for: Fel‑Pro ES 72390 is intended for professional mechanics and experienced DIYers performing cylinder head service on the specified Cadillac and Chevrolet vehicles. If your repair calls for replacement of torque‑to‑yield head bolts or you want an OEM‑grade, application‑matched kit to restore correct clamping force and sealing, this set provides the validated, ready‑to‑install solution.
