We Love Transport

Hi-Tech Radiators are very large in transport. The reason we’re growing every year in transport is the fact that we have stock on the shelf to suit most trucks, we have cores in genuine steel work at the ready.

Rapid One Day Turnaround

If a truck owner goes to a dealer they’ll wait 2 days for a radiator core replacement. At Hi-Tech Radiators we’ll have their radiator in and out in a day. Our rapid turnaround saves the truck owner and small fleet owner upwards of a thousand dollars a day, by saving them downtime, and getting them back on the road in the shortest possible time. Every year we’re able to turn these jobs quicker and quicker to keep our customers on the road sooner.

Is it a Good Idea to Replace an OEM Aluminium Radiator with a Copper Brass One?

Radiator buffs will debate for hours about their particular preferences for radiator material. It seems for every advantage that aluminium has over its main rival material, copper brass, there is a disadvantage that makes it less suitable. If you are getting to the point where an original radiator is due for replacement, these arguments are worth listening to.

When it comes down to price alone, the aluminium radiator wins hands down. This is simply because aluminium ore is found more abundantly in the earth’s crust and more of it is mined and turned into metal than copper ore. However, cheap things aren’t always the best and there are many good reasons why a copper brass radiator might still be chosen to replace an OEM aluminium one. It all comes down to robustness.


All metals corrode and if the conditions are right, they all corrode faster. Most people know that metal objects corrode far faster if they are exposed to salt water or salty air. The fact is that radiators, whether they are aluminium or copper brass, just don’t last as long close to the sea compared to those inland. What many people don’t realise is that the coolant in the radiator can be almost as corrosive as salty air. Coolants are supposed to have a percentage of antifreeze added to them, which acts as an anti corrosive element. But if the coolant is not replaced regularly, it loses its characteristics and this is when corrosion starts to have an insidious effect on the interior of the radiator.

All metals corrode, but some corrode faster than others. The reason why radiators are not made of steel is because it corrodes too quickly. Aluminium is actually an active metal, so should corrode quickly too, but it has a special property in that it makes its own protective layer of aluminium oxide on the outside surface of the radiator which helps to prevent any further corrosion. The interior can still corrode, though, especially if the coolant is not maintained regularly as has been already mentioned. When an aluminium radiator corrodes, small pin holes develop, which are very difficult to detect and repair properly.

Copper brass radiators are more resistant to corrosion. Like aluminium, they produce a greenish substance on the outside which also prevents further corrosion, but the copper does not corrode as much as aluminium. Where there is often a problem with a copper brass radiator is in the junction between the main radiator body and the head where there is a soldered join. The solder, made of lead or tin or both can corrode and leak but is easily repaired when detected.

Repairing a radiator

When a radiator develops a leak, it has to be repaired, otherwise the radiator could lose its coolant ad the engine will overheat. One critical feature of copper brass radiators that makes them superior to aluminium ones is that they are easier to repair. This is one aspect of their overall robustness. As has been mentioned already, the most likely area of a copper brass radiator where a leak occurs is the soldered area between the main body and the radiator head. This can easily be resoldered by the average mechanic. This is not the case with a leak in an aluminium radiator. Epoxy might sometimes work, but because of its tendency to crack and fail as a sealant, the only really effective repair to a serious leak is welding. Aluminium welding is a specialist job and is not usually something which the average mechanic can do. This makes it more expensive and more difficult, giving copper brass the overall advantage.
