Is your water temp gauge only doing half the job? ⚠️ Most gauges only show temperature, they won’t warn you when you’re actually losing coolant.

And that’s the problem with most factory and aftermarket temp gauges, they only tell you half the story, how hot the coolant is… not whether it’s actually still there.

That’s the scary part… 😬
because by the time temps spike🌡, engine damage is often already happening. 🤬

This is the exact problem JRP set out to solve with the GearX 52mm 3-in-1 range, and we did. 👇

Instead of running a separate low-coolant box, buzzer, messy wiring, and dash clutter, we built low coolant monitoring directly into the 52mm gauge itself.

✅ Clean install
✅ No extra boxes or external modules
✅ Early warning before damage happens

On top of that, GearX gauges also have a feature called colour pre-warn, changing colour as temperatures move outside normal operating conditions — so you don’t need to stare at numbers while driving.

If something’s wrong⚠️, you’ll know out of the corner of your eye👀, with your eyes still on the road.

Whether you’re towing, touring, running boost, losing coolant is what kills engines quietly — not just high temperatures.

The range includes:

• Water Temp + Low Coolant
• Water Temp + Oil Pressure + Low Coolant
• Water Temp + Water Pressure + Low Coolant

This isn’t just another water temp gauge.

It’s proper coolant system protection — built into a single 52mm gauge.

▶️ Watch the full overview from Aussie Arvos and see why running “half a gauge” just doesn’t make sense anymore.

💧 Most people think a water temp gauge tells the full story… ⚠️ It doesn’t.

Running an aftermarket water temp gauge is a great start — but temperature alone won’t warn you about coolant loss, pressure abnormalities, or early signs of head gasket and cooling system issues.

That’s exactly what Tyler explains in this video.

This GearX 52mm 3in1 gauge monitors Water Temperature, Water Pressure, and Low Coolant together, giving you a far clearer picture of what’s actually happening inside your cooling system, often before temperatures even move.

💧 Low Coolant Detection
Instant alerts if coolant is lost from a burst hose, damaged radiator, or off-road impact, protection that usually costs $200+ on its own, now built into the gauge.

💦 Water Pressure Monitoring (Head Guard Ultra)
Pressure changes can reveal issues like stuck thermostats or early head gasket failure, even when temperature and coolant level still appear normal.

🌡️ Water Temp with CPW (Colour Pre-Warn)
Visual colour changes and staged alerts give you time to react before things become critical.

It installs and looks like a normal 52mm water temp gauge — but it’s doing far more behind the scenes to protect your engine.

▶️ Watch the video below — Tyler explains why temp alone isn’t always enough 👇

✅ 3-Years & Still Going Strong ✅
🦘 Aussie Arvos On Their JRP Gauges 🦘

For the past 3 years, Patrick & Liam from Aussie Arvos have been running JRP gauges in both their rigs, and they haven’t skipped a beat.

Liam’s setup includes our powerful 14in1 Multi Gauge, while Patrick’s been rocking our GearX 52mm range featuring our Colour Pre-Warn (CPW) system. From brutal corrugations to remote river crossings, these lads push their vehicles, and their gear to the limit. The fact that both the gauges and sensors have held up through everything they’ve thrown at them makes us incredibly proud.

💬 But here’s the truth, no product on earth is totally infallible. Whether it’s a phone, a fridge, or a washing machine, stuff can break.

That’s why at JRP, we don’t just pride ourselves on the reliability and quality of our gauges, we back it up with real support from real people. If something ever goes wrong, if you’re stuck on an install, or if you’re not sure what you need for your build, you’re not on your own.

When you call us, you’re speaking to passionate car people, the kind who know their way around everything from general mechanical to complex auto-electrical and tuning setups. Our team genuinely cares. Every customer is a mate, and if one of our mates is in trouble, we’re here to help.

Our friendship with the Aussie Arvos crew is something we’re proud of, their journey has become part of our journey. For three years now, our gauges have helped protect their engines and drivetrains so they can keep making the content you love. And in turn, they’ve helped us do what we love, designing bulletproof gauges that protect people’s pride and joy from preventable damage and heartbreak.

We’re a proudly Australian company providing high-performance aftermarket gauge solutions at prices that won’t break the bank. Because we believe every build deserves protection, and every owner deserves peace of mind.

Visit our website to learn more about our gauge solutions and what makes them special, but as you’ve probably gathered from above, we’re a lot more than just great-looking gauges. We’re car guys building for car guys, and we’re in it for the long haul.

💧 The Ultimate Coolant Gauge 💧
🌡️ Water Temp + Pressure + Low Coolant 🌡️

Looking to protect your engine from costly coolant system failures?

The GearX 52mm 3in1 gauge with Head Guard Ultra combines three critical functions into one compact unit, designed to help you spot problems early before serious damage occurs.
________________________________________

🔧 Key Protection Features:

⚠️ Water Pressure Monitoring with High-Pressure Warning
This gauge goes beyond temp readings. It monitors internal cooling system pressure and alerts you when levels climb too high

Often the first sign of:

• A blown head gasket
• A stuck thermostat
• A faulty radiator cap

Even when temps seem normal, rising pressure can tell you something’s seriously wrong. Don’t wait for steam, get an early heads-up with GearX.

🌡️ Live Water Temp + CPW Visual Alerts
Real-time water temp monitoring with CPW (Colour Pre-Warn) gives you early visual cues before things get too hot. Great for keeping cool under pressure whether you're towing, touring, or tearing up the track.

💧 Low Coolant Sensor & Alarm
If your coolant drops unexpectedly, like after a rock hit or hose failure, the built-in low coolant sensor will trigger an alarm immediately. No more relying on factory systems that often don’t warn you until it’s too late.

💥 All three safety systems built into one high-performance gauge, for around the same price as many single-function products.

The BEST Dual Boost & EGT Gauge Is HERE 🔥
Featuring CPW – Colour Pre-Warn Alerts 🚦

Installing a proper set of aftermarket gauges is hands-down one of the best investments you can make to prevent engine damage and expensive rebuilds.

Let’s be real, factory gauges barely tell you anything until it’s too late. They don’t warn you, they don’t beep, and unless you’ve got superhuman peripheral vision, you’re probably not watching them close enough to catch a problem before it happens.

We’ve all been there (or know someone who has):
Radiator end tanks blown off, sitting on the side of the road, wishing we had some sort of early warning. That’s where a proper gauge setup makes all the difference.

________________________________________

💥 Meet the GearX 52mm Dual Boost + EGT Gauge Kit

Specifically designed for our turbo diesel 4x4 crowd, but just as useful in performance petrol builds, this compact unit delivers serious functionality:

🌀 Boost Pressure (Up to 99 PSI)

Live numeric readout dead-centre, with a configurable high-boost warning so you’re always in the safe zone.

🔥 EGT Readout (100°C–1000°C)

Exhaust Gas Temp is shown via a clear scale readout, or switch to dual-mode and get both a scale + numeric display for EGT.

⚡ Bonus Volt Monitoring

Yep, it also keeps an eye on system voltage, with a configurable low voltage warning. So technically... it’s a 3in1, but hey, we’re not here to brag 😏

🔥 The GearX 3in1 Gauges Are Here 🔥
🛢️Oil Pressure +🌡️Water Temp + Low Coolant💧

Meet the ultimate triple-threat for engine protection. The GearX 52mm 3in1 gauge combines Oil Pressure, Water Temperature, and Low Coolant Detection into one smart, compact unit, built for those who want full visibility over their engine’s health.

________________________________________________

🔧 Key Features That Make a Difference:

🛢️ Oil Pressure Monitoring

Vital for both petrol and diesel engines. A sudden drop in oil pressure can mean catastrophic damage, this gauge gives you a real-time alert if pressure drops, protecting your engine from running dry. Whether you're pushing hard on the track or towing heavy loads, this readout is a must-have.

🌡️ Water Temp Monitoring with CPW

Our CPW (Colour Pre-Warn) system gives you a visual cue as temps begin to rise, well before things get dangerous. It’s like a traffic light for your cooling system, helping you act early and avoid costly overheating.

💧 Low Coolant Detection & Alarm

A cracked hose, a loose clamp, or an off-road knock to the radiator, if coolant levels drop suddenly, this system kicks in immediately with an audible alert. Factory gauges won’t save you here, but the JRP GearX will.

This feature alone can cost nearly $200 from other brands, yet with the JRP GearX 52mm, it’s built in, at no extra cost.

Timmy Has Heart - JRP 52mm Gauge Install 🔧
In-Depth Install Video & Feedback 🎬👇

Timmy has done a brilliant job installing a set of the JRP 52mm gauges on his GU Patrol, using our 2in1 Boost & EGT, plus our latest 3in1 with Head Guard Ultra for Water Temp, Water Pressure & Low Coolant, along with an Oil Pressure gauge for good measure.

For those not familiar with Timmy’s channel yet, you really should check this guy out. Based in Tasmania, he is becoming a popular & well respected member of the Australian 4x4 community, for his informative & entertaining content, and just being an all-round good bloke.

We were really flattered he was changing his gauges from a very well-known & respected brand to ours, there was nothing wrong with his previous gauges, but he saw the features and functionality ours provided that his previous gauges didn’t, this prompted him to make the switch.

Something we at JRP enjoy is supporting these talented content creators such as Timmy, the world has changed & people like Timmy, the boys from Aussie Arvos, Tyler & Burto from the Thomspon crew bring us wholesome entertainment, valuable education, adventures and laughs along the way. We encourage anyone reading this that loves their weekend adventures and their 4x4’s to checkout what Timmy has to offer, throw him a subscribe if you enjoy his content, as we aren’t the only ones that think this talented young man deserves a bit more recognition for what he is doing for the community.

We at JRP are extremely grateful to have worked with the guys mentioned, it’s been a journey for all of us over the past 4-years or so, the boys from Aussie Arvos single handedly helped us grow almost overnight from the moment Liam put up his video installing and using our 14in1 multi gauge system, it’s created jobs here, hopes for the future, and allowed us to continue to develop more products that help people take care of their vehicles, which bring weekends away with friends & family that create memories which will last a lifetime.

So, pop over and checkout Timmy’s channel and enjoy.
