2006 Toyota Land Cruiser Radiator – Purpose, Service and Replacement Advice

A radiator is absolutely fitted to the 2006 Toyota Land Cruiser (100 Series: UZJ100/HDJ100/HZJ105). This is confirmed by Toyota’s Land Cruiser 100 Series Repair Manual (Cooling System – Radiator procedures), the Toyota Electronic Parts Catalogue listing the Radiator Assembly (PNC 16400) for 2006 models, and widely used service guides such as the Haynes manual for 1998–2007 Land Cruiser. It’s a conventional liquid-cooled setup with a cross‑flow aluminium core and plastic tanks, and most automatic models route transmission fluid through an integrated cooler in the radiator end tank.

The radiator’s job is to keep the big V8 or straight‑six diesel in its happy temperature range. Coolant absorbs heat in the engine, passes through the radiator where airflow and the viscous fan (or electric fans, depending on variant) pull that heat away, and heads back for another lap. That stable temperature means better performance, economy, and longevity—vital when towing, crawling in low range, or tackling hot Aussie and Kiwi summers.

For servicing, stick with Toyota‑approved coolant. Many 2006 vehicles run Toyota Super Long Life Coolant (pink, premixed). If the vehicle specifies the earlier red Long Life Coolant (concentrate), mix with demineralised water as directed. Typical intervals are up to 160,000 km/10 years for the first SLLC fill, then around 80,000 km/5 years thereafter
