Secure your thermostat housing correctly with this Genuine Nissan Thermostat Housing Top Long Bolt, designed to suit Nissan Patrol GQ Y60 and GU Y61 models fitted with the TD42 diesel engine. This OEM long bolt clamps the top of the thermostat housing down onto the engine, creating the critical seal against the housing gasket.

This bolt is known to rust and seize in the housing, often snapping when you try to remove it during a thermostat or coolant change. A broken or damaged bolt prevents the housing from sealing correctly against the gasket, and if left unaddressed, you will likely be left with a persistent coolant leak, which can lead to engine overheating and major mechanical failure.

Manufactured to Genuine Nissan specifications from high-tensile steel, this bolt is built to provide the correct clamping force for a leak-free seal without stretching. It's a direct-fit replacement, engineered to the exact length, diameter and thread pitch for your TD42 engine, making it the correct choice for a thermostat change, coolant service, or any job requiring housing removal on your Nissan Patrol.
