Performance Aluminium Radiators Built for Heat & Load
A massive chunk of your engine's combustion energy turns directly into raw heat. Stock copper-brass cores and brittle plastic tanks struggle the second you make extra power, run boost, or get stuck in summer traffic. Plastic end tanks crack under pressure, and clogged core tubes cause water temps to spike fast. Upgrading to performance aluminium radiators gives your cooling system the thicker core capacity, TIG-welded alloy strength, and fluid flow needed to keep operating temps rock-solid under heavy throttle. At VPW, we stock heavy-duty cooling setups from PWR and Proflow built for harsh Aussie conditions.
Direct-Fit & Universal Upgrades from Top Brands
Upgrading your cooling loop doesn’t mean you have to re-engineer your entire front clip. For classic muscle cars or daily cruisers, direct fit aluminium radiators drop straight onto your factory core mounts without cutting or welding. If you're building a custom street rod or modern V8 swap, universal car radiators give you total freedom over hose routing and core positioning.
Grabbing a complete Proflow Ultra Cool radiator kit simplifies custom plumbing by packaging the high-efficiency core, electric fan, and shroud together. We also stock all the radiator accessories you need to lock your setup down — including heavy-duty radiator mounting brackets, water neck spacers, silicone heater hoses, and stainless steel lines.
Plumb a Complete Cooling System
An upgraded core needs a reliable expansion setup as coolant expands under load. Route your overflow line into high-performance radiator overflow tanks to catch expanding fluid before it dumps onto the track.
Keep warm-up cycles predictable with high-flow thermostats, and trap rust scale using inline coolant filters. To raise your boiling point and stop steam pockets forming around combustion chambers, screw on a radiator cap high pressure unit from our billet radiator caps. As a trusted destination for aftermarket car parts, VPW supplies complete radiator kits Australia-wide.

Frequently Asked Questions
What are radiators and how do they work?
A radiator is a fluid-to-air heat exchanger. Hot coolant absorbs heat from your engine block, flows through internal core tubes, and dumps that thermal energy into cooling fins as air passes through the core.
Is replacing a car radiator a big job?
On most cars, it takes a few hours with basic hand tools. You just drain the old fluid, unhook the hoses and fan shroud, swap the core, refill, and bleed the system. If saving time is a priority, go to a mechanic directly.
How do I know if my radiator is bad?
Some telltale signs that your radiator isn’t working like it should are: coolant puddles under the front bumper, rising temp gauges at idle, or dried green or pink crust around seam welds and plastic end tanks. Sludge inside the filler neck is another dead giveaway.
What is included in a complete performance radiator cooling kit?
Most radiator kits in Australia will include a core, fitted fan shroud, electric fan, overflow tank, mounting brackets, and a thermostatic relay kit to control fan engagement automatically. The product description should mention inclusions.
How do I select the right universal radiator kit for a custom engine bay?
With so much choice, it can be tricky knowing which radiator accessories you should get. Measure your frame rail width, bonnet clearance, and pulley distance first. Pick a kit that fills the core support opening while keeping the inlet and outlet ports aligned with your water pump.
Why should I upgrade my radiator cap and overflow tank when replacing a radiator?
You may as well upgrade your radiator cap and overflow tank at the same time because old caps lose spring tension, which drops system pressure and causes premature boiling. A new cap and alloy overflow tank ensure your new radiator holds pressure and safely recovers fluid.
How to choose universal aluminium radiator size with shroud and fan?
Leave about 50mm of clearance around your core support opening for frame flex and brackets. Choose a fan shroud that covers the entire core face so air gets pulled through the whole radiator at low speeds.
Do I need a high pressure radiator cap for a performance cooling system?
Yes. Higher pressure caps raise your coolant's boiling point by roughly 1°C per pound of pressure, preventing steam pockets from forming around hot cylinder head jackets during hard passes.
