Patent Pending · South Africa
The only coolant monitoring system built for Ford Rangers — and now every vehicle on the road. Get warned the moment your coolant drops, before your engine pays the price.
The Problem
Your Ranger Has No
Coolant Warning
Ford Rangers are incredible bakkies — but they’re notorious for EGR failures and burst coolant pipes that drain your system with zero indication to the driver.
Overheating Destroys Engines
When coolant drops below a safe level, engine temperature spikes rapidly. By the time you notice, serious damage has already occurred.
EGR & Pipe Failures Are Common
EGR cooler failures and coolant hose bursts are a known issue across multiple Ranger model years — often happening without warning on the road.
Repair Bills Are Devastating
A single overheating incident can cost over R100,000 in engine replacement costs — not including towing and rental vehicles.
Why CoolStick
Built for the Road.
Built for Rangers.
Six reasons CoolStick is the smartest thing you can add to your vehicle.
Real-Time Alerts
The moment coolant drops to a critical level, your in-cab receiver gives an immediate warning. React before damage occurs.
Fully Wireless
No complex wiring through your firewall. The sensor communicates wirelessly with the in-cab alert unit — clean, simple installation.
1-Year Battery Life
The sensor runs for a full year on standard batteries. When they need replacing, it’s quick and simple — no specialist tools needed.
Auto Health Checks
If the receiver hasn’t heard from the sensor in over 24 hours, it alerts you automatically. Your system always lets you know it’s working.
USB-C Rechargeable
The in-cab receiver charges via USB-C and only needs charging once a month. Simple and convenient.
Universal Compatibility
CoolStick Hybrid is compatible with all vehicle makes and models — not just Ford Rangers. Protect any vehicle in your fleet.
