Protect your E46 cooling system with this clever polyurethane radiator support bush that repositions the lower radiator by 8 mm. Ideal when fitting thicker core performance radiators or where engine movement and soft rubber grommets allow the radiator to edge toward the belt pulleys or expansion tank, this simple upgrade delivers the clearance you need for reliable fast-road and track use.

What it does

• Moves the radiator forward by 8 mm to increase space around the expansion tank and front-end pulleys.
• Uses tough Red 65A polyurethane for stability and longevity compared with ageing rubber mounts.
• Reduces the risk of contact that can lead to leaks, fan or pulley rub, and costly engine bay damage.
• Quick fit in most cases without draining coolant, making it a straightforward upgrade.

Why enthusiasts choose it

• Confidence when running uprated, thicker core or alloy radiators on the E46 platform.
• Improved cooling pack positioning for better reliability on road, spirited driving and track days.
• Consistent location of the radiator even with worn engine mounts or increased engine movement.
• Proven on our own cars and customer builds, with excellent feedback on fit and function.
