Honda Upper Radiator Mounting Bushing 74173-SJ4-000

Honda Upper Radiator Mounting Bushing - 74173-SJ4-000

This is the OEM Honda upper radiator mounting bushing, and it does exactly one job: keeps your radiator from flopping around in its brackets. That sounds simple, but a missing or cracked bushing lets your radiator shift under load, which puts stress on the inlet and outlet necks, the hose connections, and the brackets themselves. Over time, that movement cracks things. Don't let a $10 rubber bushing turn into a $300 radiator replacement.

Part number 74173-SJ4-000 fits an enormous range of Honda and Acura platforms - we're talking everything from a '90 Integra to a current-gen Accord. If you're swapping radiators, doing a full cooling system refresh, or just noticed your radiator has a little too much wiggle when you rock it by hand, this is the part you need. It slots into the upper radiator brackets and absorbs the vibration that would otherwise transfer directly into the radiator tank.

It's OEM rubber construction, so fitment is exact - no trimming, no persuading, no "close enough." Drops right in where the factory bushing lived.

Key Features:

• OEM Part #: 74173-SJ4-000
• Fits most Honda and Acura models from 1990 to present (verify fitment for your specific chassis)
• Installs in the upper radiator brackets to secure the radiator
• OEM rubber construction - exact factory fitment, no modification needed
• Isolates the radiator from engine and chassis vibration to prevent stress cracking

*Most chassis require (2) bushings for a complete upper radiator installation. We recommend picking up two while you're in there.
