Is your Mazda CX-7's power steering whining or getting hard to turn? This replacement power steering pump (part number 21-5497) might be what you need. It comes with the pulley already attached, which can save you some hassle during installation. It's a direct fit for the 2007-2012 Mazda CX-7 with the 2.3L engine, and also for the 2010-2012 models with the 2.5L engine. Replaces OEM numbers like EG2132600, EG2132600A, EG2132650, and several others – check your old pump to be sure. The pump itself is new (not remanufactured) and made to meet or exceed OE specifications for reliability. It does NOT include the fluid reservoir – you'll reuse your old one. We recommend having a professional mechanic install it to ensure everything's hooked up right and bled properly. Comes as one complete pump unit. Get your smooth, easy steering back.
