If you notice any fluid seepage, replace the plugs immediately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the old plugs if they appear undamaged?\u003c\/strong\u003e\u003cbr\u003e\nA: While visually intact plugs may seem reusable, the sealing surfaces can degrade over time from exposure to hydraulic fluid and heat cycles. For reliable long-term performance and to prevent future leaks, we recommend replacing them with new parts during trim system maintenance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need any special tools to install these plug assemblies?\u003c\/strong\u003e\u003cbr\u003e\nA: Basic hand tools are typically sufficient—you'll need an appropriately sized wrench or socket to remove the old plugs and install the new ones. A torque wrench is recommended to ensure proper tightening without over-torquing and damaging the reservoir threads.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between OEM and aftermarket plugs?\u003c\/strong\u003e\u003cbr\u003e\nA: This listing is an aftermarket replacement part (not an OEM component).
