Designed specifically for the GU Nissan Patrol TD42, this fully sealed 150A water-cooled alternator kit prevents the mud, water and dust ingress that commonly destroys conventional air-cooled alternators. Not compatible with GQ unless you only run one drive belt and don't need a vacuum pump on the alternator.

Why water-cooled?
Conventional air-cooled alternators rely on airflow through the housing to keep them cool. Unfortunately, that same airflow also pulls in mud, sand, dust and water - the very things that eventually destroy them.
Anyone who’s drowned or cooked an alternator knows how common it can be.
A water-cooled alternator is fully sealed, so nothing gets in. No mud, No sand, No water, No dirt.

More output than factory
Whether you're touring, camping or running power hungry accessories, extra charging capacity quickly becomes essential.
These kits use a Bosch style alternator. Producing up to 150 amps, these kits provide substantially more charging capacity than the factory alternator, making them ideal for running things like:
✅ Winches
✅ Fridges
✅ Dual Batteries
✅ Compressors
✅ Lights
✅ Inverters
✅ Induction Cooktops
The alternator itself is not proprietary. If it ever needs replacing, you can source a Bosch-style replacement from most major parts suppliers. You're never locked into buying an expensive manufacturer-only alternator.
How It Works
Unlike a conventional alternator that relies on airflow, our alternator is cooled by engine coolant flowing through the housing. This allows the entire unit to remain completely sealed against mud, sand, water and dust while still efficiently removing heat.
It integrates into your existing cooling system using the supplied hoses and fittings. No additional pumps are required.
What’s included
✅ 150A water-cooled alternator
✅ Engine-specific mounting brackets
✅ All mounting bolts and hardware
✅ Plug-in wiring adapter
✅ Coolant hoses, clamps and AN fittings
Nothing extra required. Just bring your hand tools.
Installation Instructions
Are you sick of receiving a piece of paper with black and white photos that you can barely make out what's going on? So are we! That's why we have recorded an installation video to walk you through the process step by step.
Installation is straightforward and can be done with basic hand tools. No special wiring knowledge needed. If you can change a standard alternator, you can fit this.
Charge Cable
The factory charge cable was never designed to carry the increased current produced by a 150A alternator.
We strongly recommend upgrading your charge cable during installation.
If you don't already have one, you can add one to your order here.
Designed & tested by House of Hoon
Every kit has been designed and tested by us here in Australia.
These weren't developed for showroom 4WDs. They were developed for people who actually use their 4WDs in mud, water, dust and harsh conditions.
If you rely on your vehicle when you're off-road, this kit was built for you.
