OFFICIAL NZ MASTER DISTRIBUTOR — DAVIES CRAIG Fast NZ Delivery: In-stock local inventory dispatched daily via tracked express courier | Full NZ GST Invoice Provided Complete thermal precision with easy radiator fin probe sensing, IP67 waterproofing, 12V/24V versatility, and 5-second staged dual-fan control. The Davies Craig Digital Thermatic® Fan Switch Kit Gen II (Part #0480 / DC-0480) directly supersedes the older 0444 model. Supplied with a stainless steel radiator fin temperature probe, this unit slides directly into your radiator cooling fins near the hot coolant inlet—delivering fast thermal response without cutting hoses or modifying coolant ports. What's New & Upgraded in Gen II (#0480 vs #0444) Engineered for extreme performance, heavy towing, 4WD, and motorsport environments: - Non-Invasive Radiator Fin Probe: Temperature sensor slides directly between radiator core fins for clean installation without draining coolant or opening fluid lines.
- Upgraded IP67 Waterproof Casing: Fully sealed against high-pressure water washdowns, mud, dust, and engine bay grime.
- Faster 5-Second Dual Fan Staging: Fan #1 activates immediately at your set temperature, while Fan #2 engages 5 seconds later (upgraded from 10 seconds on older models) to prevent heavy 60A electrical inrush spikes.
- Expanded Temperature Range (5°C to 110°C / 41°F to 230°F): Push-button target setting with digital memory retention even when the vehicle battery is disconnected.
- Dual LED Segment Display: Real-time digital readout shows actual live radiator temperature and target set point. Toggle easily between Celsius (°C) and Fahrenheit (°F).
- Integrated A/C Override Wires: Includes two manual override signal wires supporting positive (+12V air conditioning compressor clutch) or negative trigger signals to force fans on when A/C is active.
How It Operates - Target Activation: Fan #1 turns on automatically when radiator temperature hits your programmed target set point.
- Staged Second Fan Delay: If operating dual cooling fans, Fan #2 starts 5 seconds after Fan #1 to smooth out alternator load and prevent voltage drops.
- 5°C Cool-Down Hysteresis: Both fans run continuously until radiator temperature drops 5°C (9°F) below your set target, preventing rapid on/off relay chatter.
- Air Conditioning Override: Automatically triggers both fans whenever the A/C system is turned on to maintain sub-condenser cooling.
