• Toyota Hilux N70 – 1KD-FTV 3.0L 4-Cylinder Turbo Diesel | 2005–2015
• Toyota Hilux N70 – 1GR-FE 4.0L V6 Petrol | 2005–2015

✅ OEM-style install with model-specific brackets and hardware

How It Works: Installs inline with your transmission cooling system, providing superior heat dissipation through an advanced fin-and-plate core. Whether towing, beach driving, or touring—this cooler keeps ATF temperatures in the safe zone, protecting your transmission from heat damage.

Key Features:

• 32mm, 14-row plate and fin cooler — Arctic Black powder-coated
• Drops ATF temps by up to ~33°C under heavy load
• Up to 50% more efficient than tube and fin designs
• Internal turbulators for maximum heat transfer
• Pressure tested to 150 PSI — no leaks, no compromises
• M16 fittings for clean, leak-free install
• Davies Craig quality — Australian-made cooler
• Laser-cut 4mm alloy brackets (5005-H34)
• SAE J1019 ATF hose (400 PSI burst rating)
• 3-year manufacturer warranty (conditions apply)
• Direct bolt-on installation

💡 Why This Matters: Heat is the #1 killer of automatic transmissions. ATF life drops rapidly above ~93°C—seals fail, clutches slip, and expensive damage occurs. This cooler drops temps into the safe zone, dramatically extending transmission life. Lower temps = longer clutch and seal life, better shift quality, and confidence when towing, beach driving, or touring.

Heat destroys transmissions. Every time you tow, drive in sand, climb hills, or sit in traffic on a hot day, your transmission fluid heats up. Excessive heat breaks down ATF, accelerates wear, and damages seals—leading to expensive failures.

Benefits:

• 💥 Prevents transmission overheating — especially when towing or in sand
• 🧊 Drops ATF temps by up to 33°C under heavy load
• ⚠️ Keeps temps below 93°C — the critical threshold for ATF breakdown
• ⏱ Extends ATF and transmission life — proven science
• 🛡️ Protects clutches and seals from heat damage
• 💰 Saves thousands in potential transmission repairs
• 🚛 Essential for towing — keeps temps safe under maximum load
• 🏖️ Perfect for beach driving — sand and slow speeds generate heat

💡 The Science: For every 10°C increase in transmission temperature above normal operating range, ATF life is cut in half. By keeping temps down, this cooler can literally double or triple the life of your transmission fluid and internal components. It's cheap insurance for an expensive component—especially on the hardworking N70 platform.

✅ Complete kit — everything needed for installation included

Recommended: Competent qualified mechanic or experienced DIYer

DIY Time: 2–3 hours

Installation Notes:

• Mounts in front of radiator for maximum airflow
• Laser-cut brackets designed specifically for N70
• Plumbs inline with transmission cooling lines
• OEM-style installation — direct bolt-on
• All fittings and hoses included
• Works with both 1KD-FTV (3.0L diesel) and 1GR-FE (4.0L V6 petrol)

Important Notes:

• Requires working with transmission fluid lines
• Small top-up of ATF needed for cooler/hose volume
• Check ATF level hot, in Park/Neutral, after cycling gears
• Generally compatible with bull bars and accessories
• Ensure proper airflow and avoid hose kinks

Important: Installation requires working with transmission fluid lines. If not comfortable with this type of work, professional installation is recommended. Detailed installation guide included with kit.

Maintenance Schedule:

• Visual inspection during regular services
• Check for leaks at fittings and connections
• Inspect cooler for physical damage (rock strikes, debris)
• Clean cooler fins if blocked by mud or debris
• Monitor ATF level and condition regularly
• Check ATF temperature if gauge equipped

💡 Pro Tip: The Arctic Black powder-coated finish is tough, but if you frequently drive in mud, sand, or water, occasionally rinse the cooler core with a gentle stream to prevent debris buildup. This ensures maximum airflow and cooling efficiency—especially important for beach driving where salt and sand can accumulate.

Q: Will this void my Toyota warranty?

A: No. Aftermarket transmission coolers don't void warranty under Australian Consumer Law. They're a common upgrade for vehicles used for towing or heavy-duty work.

Q: Does this fit both the diesel and V6 petrol N70?

A: Yes! This kit is designed to fit both the 1KD-FTV 3.0L diesel and 1GR-FE 4.0L V6 petrol N70 Hilux models (2005–2015). The mounting brackets and fittings work with both variants.

Q: Do I really need a transmission cooler?

A: If you tow, drive in sand, tackle steep climbs, or drive in hot climates—absolutely. Even if you don't, a transmission cooler extends ATF and transmission life significantly. It's cheap insurance for an expensive component, especially on a workhorse like the N70.

Q: How much cooler will my transmission run?

A: This cooler can drop ATF temperatures by up to 33°C under heavy load (towing, sand, hills). Even moderate reductions of 15-20°C make a huge difference to transmission longevity.

Q: Why is 93°C the critical threshold?

A: Above 93°C, automatic transmission fluid begins to break down rapidly. Oxidation accelerates, viscosity changes, and additives degrade. This leads to clutch slippage, seal damage, and accelerated wear. Keeping temps below this threshold is critical for longevity.

Q: What makes plate and fin coolers better than tube and fin?

A: Plate and fin design has up to 50% more surface area for heat transfer in the same size package. This means better cooling efficiency in a more compact unit—perfect for the N70's engine bay.

Q: What are internal turbulators?

A: Turbulators are internal baffles that create turbulent flow through the cooler core. This increases heat transfer efficiency by preventing laminar flow—meaning better cooling performance from the same size cooler.

Q: Do I need to add extra ATF?

A: Yes — a small top-up is required to account for the cooler and hose volume (typically 0.5-1L). After installation, check ATF level hot, in Park or Neutral, after cycling through all gears. Top up to the correct level.

Q: Can I install this myself?

A: If you're mechanically competent and comfortable working with transmission lines, yes. The kit is bolt-on with N70-specific brackets. Most DIYers complete installation in 2-3 hours. Otherwise, any qualified mechanic can handle it.

Q: Will this fit with my bull bar?

A: Generally yes. Most aftermarket accessories don't interfere, but ensure proper airflow and avoid hose kinks during installation. The compact 32mm design helps with fitment.

Q: Why is 150 PSI pressure testing important?

A: Transmission systems operate at high pressures, especially under load. A 150 PSI pressure test ensures no leaks under normal or extreme operating conditions. Davies Craig quality means reliability you can trust.

Q: What's the Davies Craig warranty?

A: Davies Craig provides a 3-year manufacturer warranty on their coolers (conditions apply). This demonstrates the quality and durability of their Australian-made products.

Q: What's the Arctic Black finish?

A: The Arctic Black powder-coated finish provides excellent corrosion resistance—especially important in Australian conditions with mud, water, salt (beach driving), and harsh weather. It also looks professional and resists rock chips.

Q: Is this suitable for beach driving?

A: Absolutely essential for beach driving. Sand driving is one of the hardest workouts for a transmission—slow speeds, constant resistance, and high loads generate significant heat. A transmission cooler is critical protection for regular beach use.

Q: Will this help with shift quality?

A: Yes! Transmissions shift better when ATF is in the optimal temperature range (70–90°C). Overheated fluid affects shift quality and feel. A transmission cooler helps maintain consistent, smooth shifting, especially under load.

Q: Is this suitable for extreme towing?

A: Absolutely. This cooler is designed specifically for heavy towing, off-road, and challenging conditions. If you regularly tow at or near your N70's capacity, a transmission cooler is essential protection.

Q: Does this work with both manual and automatic transmissions?

A: This kit is designed for automatic transmissions (which have fluid cooling systems). Manual transmissions don't typically use fluid coolers.
