Nissan NP200 1.6 16V (K4M) Thermostat Housing Cover Outlet Kit + Genuine Nissan Antifreeze (5 Litres)

Restore full cooling system integrity and prevent costly engine overheating with the Nissan NP200 1.6 16V (K4M Engine) Thermostat Housing Cover Outlet Kit bundled with Genuine Nissan Long Life Antifreeze / Coolant (5 × 1L Bottles). Designed specifically to resolve common coolant leakage and plastic warping issues typical to Renault-sourced K4M 16-valve petrol powerplants, this complete replacement set provides reliable pressure sealing, balanced coolant flow, and factory-certified protection against corrosion, boiling, and freezing.

Over extended operational periods, factory composite thermostat housings suffer from continuous heat-cycling, which often leads to hairline fractures, flange warping, and slow coolant loss along the mating face. This comprehensive service pack pairs a direct-replacement reinforced water outlet cover with the exact OEM coolant chemistry specified by Nissan and Renault for aluminium engines.

Key Features & Benefits:

• Engine-Matched Direct Fitment: Engineered precisely to OEM bolt patterns and hose outlet dimensions for the Nissan NP200 1.6 16V (K4M engine), ensuring seamless fitment to the cylinder head without trimming or alterations.
• Reinforced Thermal & Chemical Resistance: Manufactured from heavy-duty, heat-stabilized composite polymer formulated to withstand continuous coolant pressure, hot thermal cycling, and acidic breakdown without distorting or weeping.
• Leak-Free Sealing Surface: Includes a fresh, high-grade elastomer gasket/seal to create a tight, pressure-resistant seal against the engine block mating face, eliminating persistent coolant seepage and system pressure drops.
• Genuine Nissan Engine Protection: Supplied with five 1-litre bottles of Genuine Nissan Long Life Coolant / Antifreeze, ensuring zero chemical incompatibility, optimal heat transfer, and complete corrosion protection for all aluminium cylinder head and block passages.
• Prevents Cavitation & Corrosion: Advanced anti-corrosive additive package lubricates water pump seals, prevents internal scale formation, and guards against cavitation pitting in high-temperature water jackets.
• All-in-One Service Pack: Provides both the physical cooling system outlet component and the correct fluid volume needed to complete a thorough cooling system bleed and refill.

Ideal Applications:

• Thermostat Housing Leak Remediation: Permanent fix for weeping, warped, or cracked plastic thermostat housings and outlet necks on K4M engines.
• Scheduled Cooling System Overhauls: Essential replacement component when renewing water pumps, timing belts, radiators, or cylinder head gaskets on the NP200.
• Fleet Maintenance & Daily Work Bakkies: Restores factory cooling efficiency and reliability on hard-working commercial delivery NP200 bakkies subjected to heavy stop-and-start traffic.
