Terrain Tamer Radiator Hose Kit LandCruiser HDJ78 HDJ79 1HD-FTE Top Bottom Turbo Hoses

Terrain Tamer radiator hose kit to suit LandCruiser HDJ78 and HDJ79 with 1HD-FTE engine.

Includes top and bottom radiator hoses along with turbo-related hoses for a complete cooling system refresh.

 

This kit is a complete radiator hose solution for 1HD-FTE turbo diesel engines.

 

It includes:

 

• Upper radiator hose
• Lower radiator hose
• Turbo water hoses (where applicable)

 

 

Designed as a matched set, it ensures all critical coolant hoses are replaced at once, reducing the risk of future failures.

 

These kits are commonly used during:

 

• Cooling system overhaul
• Touring preparation
• High kilometre maintenance

 

 

A full hose kit is preferred over replacing individual hoses, as ageing hoses tend to fail around the same time.

This kit maintains:

 

• Proper coolant flow through the engine
• Stable engine temperature under load
• Reliability of turbo cooling circuit

 

 

On 1HD-FTE engines:

 

• Turbo hoses are critical
• Heat load is higher than 1HZ

 

 

 

 

 

When this kit is needed

 

 

Common scenarios:

 

• Hoses soft, swollen or cracked
• Coolant smell or minor leaks
• Preventative maintenance before trips
• Engine rebuild or radiator replacement

Common Questions

 

 

Does this include all hoses?

Covers main radiator and turbo hoses (not heater hoses).

 

Is this for 1HZ?

No — turbo 1HD-FTE only.

 

Why replace all hoses together?

Old hoses fail around the same time — prevents repeat failures.

 

Is this better than buying individual hoses?

Yes — more complete and reliable solution.

Complete cooling hose kit for 1HD-FTE — replaces all critical radiator and turbo hoses in one job.
