Aluminum Advances, Copper/Brass Retains Market Leadership The radiator environment altered in the 1970s. Volkswagen made the decision to go from an air-cooled engine to a water-cooled engine at the beginning of the decade. A few years later, major automakers in Europe and the U.S. started producing vehicles and trucks with lighter materials in response to the global oil crisis and the urgent need to find ways to cut fuel usage.
This meant that aluminum, which is one third the density of copper or brass and can tolerate heat reasonably well despite its many drawbacks, was the best material for radiators. Aluminum is cheaper in its raw form (albeit not as radiator strip). These characteristics sparked interest in something new, along with the grim, though unfulfilled, forecasts of commodities analysts that copper and brass would be in limited supply in the 1980s.
Because of this, aluminum has overtaken copper/brass as the preferred material for radiators in new cars during the past 20 years (56% to 44%), even though copper/brass still commands a two-thirds majority of the market for radiators as a whole. With 89% market share, copper/brass dominates the aftermarket.

The cost of a brand-new VW radiator
Best in Automotive Repair A Volkswagen Jetta radiator replacement typically costs between $1,259 and $1,383. While parts are priced between $930 and $968, labor costs are predicted to range between $329 and $415.
What kind of vehicles lack radiators?
There is a very good probability that you are familiar with what is referred to as a radiator if you owned a car in the preceding ten years. A radiator is a device that circulates water that has been cooled by air to cool the engine of a vehicle.
Most cars and even airplanes have used radiators as engine coolers for many years. However, air-cooled engines were included in a few mid-20th century car models before radiators became fairly common.
As the name suggests, air-cooled engines often produce a lot more airflow than radiators. It has long been the favoured option among aircraft manufacturers, and now automakers are starting to follow suit.
An air-cooled engine has benefits like lighter weight and better airflow. Stricter emission standards, which are easier on radiator engines, are a significant drawback.
The following is a list of well-known automobiles without radiators:
Do every automobile have a radiator?
Internal combustion engines, which are found in most cars, including modern cars, generate a lot of heat during combustion. To prevent internal engine part damage, the heat generated still needs to be cooled, necessitating the installation of a radiator. Modern cars can appear to have no radiator under the hood at first glance, but this is only because the radiator is concealed.
Is there a radiator in the new Volkswagen Beetle?
Rear-wheel drive was a common feature of the Beetle, which makes sense given where the engine is located.
The Beetle was also air-cooled rather than water-cooled. As a result, the radiator was missing from the Beetle. At least Beetle drivers weren’t required to travel with emergency water bottles in case the radiator ran dry.
Does fixing a radiator make sense?
If not properly maintained, the radiator hoses, core, and housing might develop tiny holes and broken portions. Because the cooling system is essential to the health of your car, it’s best to fix any issues with it right away, either by yourself or by hiring a specialist.
What results in a radiator leaking?
One might list the number of potential causes of a radiator leak in an automobile. The radiator’s rust is the primary and most frequent reason. Radiators, hoses, and hose connections gather dirt and rust over time, which can eventually cause the radiator to rust through. Overheating may occasionally be caused by a poor coolant. Poor service procedures also damage the radiator, though this should not be a concern if serviced by an expert. For instance, higher water pressure from overfilling the radiator may result in leaks. Additionally, an inefficient heater core or thermostat might put too much strain and heat on the radiator.
While at the gas station, check the strength of your coolant and the level of your radiator. Never inspect the radiator while the engine is hot; always do so while the engine is cold. When you are in the garage, ask a mechanic to check the fluid. When changing the oil or performing other engine-related maintenance, mechanics routinely inspect for a radiator leak. The invoice frequently includes check marks for routine maintenance a mechanic does on a vehicle. Ask the mechanic about the radiator if you have any questions. Since they are professionals, they will know as soon as they see an issue. Aside from that, avoid purchasing cheap coolant.
Always have the radiator system flushed while getting new radiator fluid. Rust and sediment buildup in the hoses and passageways can result in a clog. The engine can overheat as a result of this and develop radiator leaks. The radiator is actually eaten away by rust.
How can you tell if the radiator in your car is leaking?
Ensure that the fluid leaking is coolant and not another first. (Although coolant is frequently mistaken for antifreeze, it is actually a 50/50 mixture of the two.) The coolant level in your transparent overflow tank may be plainly checked. Checking the coolant level in the radiator should come next if it is empty or low, but only after the engine has cooled. Insufficient coolant in the cooling system of your car might lead to overheating of the engine and/or chilly air blowing from the cabin heater.
When coolant loss is detected, checking the radiator is an excellent place to start. Some radiator leaks, like puddles behind the radiator, will be simple to identify, while others won’t be as simple. It is best to examine the radiator from all sides, not only from above, and to pay close attention to any seams or protrusions from the bottom. Coolant leaks can also be brought on by holes from road debris or rust inside the radiator. Although the radiator in your car is made of aluminum, which is supposedly impervious to rust, metal can nevertheless corrode or develop pinhole leaks.
Different hues of antifreeze are available.
For instance, colors like green, yellow, and pinkish-red feel slimy and typically smell delicious. If you cannot detect coolant trickling or seeping, check the radiator for rust, tracks, or discoloration. Those are obvious indications of the leak’s location.
If the radiator seems to be in good condition, the cooling system has a number of potential leak points, including the radiator cap, water pump, engine block, thermostat, reservoir tank, heater core (a small radiator that circulates hot coolant into the dashboard for passenger-compartment heating), and others. Another possibility is a ruptured gasket between the cylinder head and engine block, which would result in coolant entering the combustion chambers and necessitate prompt attention from a mechanic. (Steam, a warning sign, is actually flowing from the tailpipe while there is thick white smoke.)
Check it out with a mechanic if you can’t discover a leak. When the automobile is operating, coolant has a means of escaping only under pressurepossibly as steam, which might not leave a trace. You can think about using a radiator stop-leak additive, which is available at auto parts stores and stops small leaks, if the offender manages to elude discovery. However, it’s always preferable to identify and fix the root of the issue, particularly when it comes to damaged head gaskets, which can cause your power supply to overheat and seriously harm your engine.
How can I replace a radiator?
Radiator Replacement Procedure
- Security first. There are electrical connections on your radiator.
- Examine or replace.
- Radiator draining
- Radiator must be unplugged.
- Get rid of the old radiator.
- Reinstall the Radiator.
- Include Coolant.
- Bleed the cooling system’s air.
Does an engine that is air-cooled have a radiator?
A radiator, a water pump, coolant, hoses, or any other connected parts that a liquid-cooled engine has are not required for an air-cooled engine. Is this, however, really a good thing?
Undoubtedly, an air-cooled engine has no issues with coolant leaks and will never need the water pump or radiator replaced, which can be fantastic. They often have fewer parts than liquid-cooled engines, which makes them lighter as well.
When driving in extremely cold weather, air-cooled engines warm up far more quickly than liquid-cooled engines and don’t run the risk of the coolant freezing.
But there are also some major disadvantages. To begin with, air-cooled engines have a higher risk of overheating. Yes, that is unfortunate. Additionally, they may cost more to construct, and the big fans necessary to cool the engine may consume a lot of power.
This is not to say that air-cooled engines are unreliable or inefficient. In truth, the air-cooled engine performs superbly in motorcycles, recreational vehicles, and several types of aircraft. On automobiles, however, it is generally agreed that the disadvantages exceed the advantages.
Air-cooled Engine FAQ
Coolant leakage issues are not an issue with air-cooled engines. They often have fewer parts than liquid-cooled engines, which makes them lighter as well. Additionally, they don’t run the risk of the coolant freezing and warm up much more quickly than liquid-cooled engines.
An air-cooled engine works on the principle of letting air flow over the engine to keep it cool.
For the purpose of removing heat, air-cooled engines include fins that extend from the engine. After then, cool air is often blown over the fins by a fan in an automobile.
Overheating is more frequent in engines that are air-cooled. Additionally, they may cost more to construct, and the big fans necessary to cool the engine may consume a lot of power.
The air-cooled engine performs incredibly well in motorbikes, leisure vehicles, and some types of aircraft. On automobiles, however, it is generally agreed that the disadvantages exceed the advantages.
How long is the lifespan of a VW air-cooled engine?
For standard engines, I’ve discovered that the lifespan is roughly 60,000 miles. Only the heads in each instance were responsible for the breakdown. 100,000 miles was not that exceptional for engine cylinders and bearings that had been properly maintained and operated. “Your mileage may vary” is especially applicable to buses.
I frequently solely do heads and rings. Without separating the case, the crank and rod bearings are inspected.
Regardless of mileage, cars that are not driven frequently may require a teardown every 1020 years due to leakage from hardened, shrinking seals.
If my radiator is empty, what happens?
Driving with low coolant levels might harm specific vehicle components, necessitating costly repairs. Here are a few potential consequences of driving with low coolant.
Your engine could overheat.
Coolant aids in removing heat from the engine. Therefore, if there is not enough coolant, the engine may overheat or seize. Continuous operation of an overheated engine may result in lasting harm, such as the welding of the pistons to the cylinders.
You could blow a head gasket.
If you’ve ever used the phrase “I’m going to blow a gasket” to describe how you’re feeling, you know that this is bad news for your engine. A blown head gasket on your engine block can occasionally be brought on by low coolant. If this occurs, you can see smoke coming from the engine or tailpipe, lose power, hear banging noises from the engine, or notice decreased efficiency.
Your car could shut off.
Some vehicles have a safety feature that turns the engine off automatically before it sustains serious damage, which can happen when the coolant level is low. Depending on where you are driving when the engine shuts off, this could assist save you from needing expensive repairs due to an overheated engine.
