Collection: 70 Series Land Cruiser Cooling System

COOLING SYSTEM PARTS FOR THE 70 SERIES

KEEPING THE ENGINE COOL UNDER REAL LOAD

A 70 Series engine works hardest when the cooling system is least equipped to keep up. Towing a caravan up a long hill, slow crawling through a rocky track with little airflow over the radiator, or sustained outback driving in 40 degree ambient temperatures all push the cooling system to its limits. The factory radiator on an older HZJ or early VDJ is often barely adequate when it was new and is now twenty years old. Replacement radiators, water pumps, thermostats, hoses, and fan assemblies in this collection cover the cooling system parts that fail with age and the upgrades that give the engine the cooling capacity it actually needs.

OEM AND HEAVY-DUTY RADIATORS

Radiators are available in OEM-spec aluminium or copper-brass for like-for-like replacement, plus heavy-duty options with thicker cores, higher tube counts, and bigger tank capacity for vehicles working hard. Water pumps come as OEM-spec replacements with fresh seals and bearings. Thermostats are matched to the original temperature rating, with cooler-temp options available for vehicles running performance upgrades. Hoses are silicone or rubber with appropriate temperature ratings. Fan clutches and viscous couplings are replacements for the failed factory units that lock up or fail to engage.

ENGINE CODE SPECIFIC FITMENT

Cooling system parts are matched to the specific engine because the 1HZ, 1HD-FTE, 1VD-FTV V8, 1FZ-FE petrol, and 1GD-FTV 2.8L all use different radiators, water pumps, and thermostat configurations. Each listing confirms exact engine code, body style, and year range before you order. Many cooling components also fit the 60 Series, 80 Series, and 100 Series where the same engine is fitted in a different body. Cross-fitment is flagged in each listing for owners running mixed-vehicle workshops.
