2005-2021 Nissan & Suzuki 4.0L V6 Cylinder Head Gasket Set
The Partsology HGB648 cylinder head gasket set with head bolt kit is designed for 2005–2021 Nissan and Suzuki vehicles equipped with the proven 4.0L V6 engine, including popular models like the Nissan Xterra, Frontier, Pathfinder, NV1500/NV2500/NV3500, and the Suzuki Equator. This durable 4.0L V6 is known for its strong torque, towing capability, and long service life, but like any engine, a failing head gasket can quickly lead to serious damage if ignored. Common signs of a failing head gasket include engine overheating, white exhaust smoke, coolant loss with no visible leaks, or milky residue in the oil. Replacing the head gasket set before complete failure helps prevent warped cylinder heads, internal coolant leaks, and costly engine repairs. This complete set includes new head bolts, which are critical because torque-to-yield bolts can stretch over time and should always be replaced to ensure proper clamping force and long-term sealing. Partsology supplies OEM-quality engine parts at amazing prices, giving you confidence in both fitment and reliability, and with overnight delivery available, you can get your vehicle back on the road fast.
