PHILTOP Belt Tensioner Pulley 39339 - Durable Replacement for Honda

Our review of the PHILTOP Belt Tensioner Pulley 39339 examines whether this replacement assembly is a practical choice for owners of select Honda and Acura models. The bottom line: it is aimed at DIY mechanics and independent shops who need a direct-fit tensioner that matches OEM references and reduces belt noise, with the key selling point being its labyrinth seal and damping system which together target longer service life and quieter operation.

Key Features

• Direct fitment: Designed to replace OE reference 39339 and fit multiple Accord, Civic, CR-V, TLX and HR-V model years for straightforward installation.
• Labyrinth seal protection: The labyrinth seal helps shield internal components from contaminants to meet or exceed original service life expectations.
• Vibration damping: A tested damping system absorbs extreme vibration to protect the tensioner, drive belts and accessory components for longer life.
• Torsion spring design: The torsion round spring provides steady, reliable belt tension for consistent accessory drive performance.
• OEM-level manufacturing: Built using the same or improved technology and materials as original equipment to ensure a factory-like match.

Who It's For

This tensioner is best for owners of 2013-2017 Honda Accord 2.4L, 2015-2019 CR-V, 2016-2022 Civic (including LX and EX variants listed), 2015-2020 Acura TLX 2.4L and 2023 HR-V who prefer a direct replacement that emphasizes seal protection and vibration damping. It is well suited to DIY installers and independent shops that want a component built to OEM standards without sourcing dealer parts.

Customers with vehicles outside the listed fitment, or those seeking heavy-duty or performance-grade tensioners beyond the OEM spec, should look elsewhere; this part is positioned as an OEM-style replacement rather than a high-performance upgrade.
