Eurospare AJ89486 Engine Coolant Thermostat Housing & Outlet Assembly

The Eurospare AJ89486 is a complete engine coolant thermostat housing and water outlet pipe assembly, designed as a direct OEM-specification replacement for Jaguar 4.2L naturally aspirated engines. This assembly includes the thermostat housing, integrated water outlet, and thermostat, providing everything needed to restore proper engine cooling system function in a single kit.

The thermostat is a critical engine management component that regulates coolant flow between the engine and radiator, keeping the engine operating within its optimal temperature range. A faulty thermostat housing or thermostat can cause coolant leaks, engine overheating, or a chronically under-heated engine — all of which reduce performance and risk long-term engine damage.

Key Features:

• Complete assembly including thermostat housing, water outlet, and thermostat
• OEM-equivalent fit and function for precise, leak-free installation
• Constructed from durable materials for long service life
• Direct replacement — no special tools or modifications required
• Backed by Eurospare's quality engineering standards

OEM & Cross-Reference Part Numbers: AJ89486, AJ89200, AJ87365, AJ85887

This assembly is intended for the naturally aspirated (non-supercharged) variant of the Jaguar 4.2L engine. Professional installation is recommended to ensure proper torque and coolant system integrity.
