Genuine Nissan Lower Thermostat Housing TD42 - Nissan Patrol Y61 GU 1999-2003

This is the lower section of the thermostat housing, fitted directly to the engine block on the TD42T engine in a Y61 GU Patrol. It's a critical part of your cooling system that directs coolant flow. The original cast alloy housing can corrode and become pitted, especially on the gasket mating surfaces. This damage prevents the gasket from sealing properly, causing persistent and hard-to-fix coolant leaks. Ignoring a leaking thermostat housing will lead to coolant loss, which directly causes overheating and can result in catastrophic engine damage like a warped cylinder head.
