When it comes to replacing car parts, there are a few worse things than being told that the part you need is no longer manufactured.
Even if you’re lucky enough to find a replacement that works, it probably won’t be an exact match for the original—and if it isn’t an exact match, your car may not run as well as it used to.
With all of the different parts that make up a car, it can be hard to know which ones are the most vulnerable. That’s why we decided to take some time and look at 8 of the hardest parts to replace.
So, are you ready? Let’s begin!
8 Of The Hardest Car Parts To Replace
1. Radiator Hose
The radiator hose is one of the most common car parts to fail. It connects the engine and radiator, allowing coolant to circulate through both components.
The hose is typically made up of rubber tubing with an aluminum core running through it. Over time, this core can become brittle and crack, causing leaks in the system.
The radiator hose is difficult to replace because it’s designed specifically for each make and model of vehicle.
In other words, there are different hoses for different cars. You may be able to find a replacement radiator hose at your local auto parts store, but chances are that it won’t fit properly or function as well as the original part did when installed by the manufacturer.
Keep in mind that the best way to prevent car part replacement is to take good care of your car. And buying an appropriate insurance policy from a reputable provider like NRMA is one way to do this.
2. Dashboard Panel
The dashboard panel can be a hard car part to replace. This is because it comprises multiple parts and is attached to other components within the car’s interior. This means you’ll need to remove some other parts as well before accessing the dashboard panel.
In addition, dashboards are unique to each car, which makes replacement a challenge. Even if you can find a similar dashboard, the plastic clips that hold it in place may be different.
3. Steering Shafts
The steering shaft is a very important part of your car, and if it breaks, you will not be able to drive your vehicle
The steering shaft is the link between the gearbox and the steering wheel, making it the backbone of how you control your vehicle. If it breaks or wears out, you’ll have to replace it.
The hardest part about replacing a steering shaft is finding one that fits exactly as the old one did.
If you have access to an auto parts store that stocks many different types of steering shafts, then you may be able to find one that fits perfectly into your car’s engine compartment without having to make any modifications to either piece of equipment.
4. Manual Transmission
Automatic transmissions have become the dominant choice for new vehicles, so manual transmissions are becoming harder to find.
Manual transmissions are not only harder to replace than automatics, but they’re also more expensive because they require an extra shift linkage and clutch pedal assembly that automatics don’t need.
5. Aluminum Valve Covers
Aluminum valve covers are made up of a soft metal that can crack or warp when it’s improperly tightened or over-tightened. When this happens, you’ll have to replace your valve cover entirely in order to fix the problem.
Unfortunately, these valve covers are expensive, each costing around $150-$200 even if you get it from a thrift market. So if you want to get yourself a new set of aluminum valve covers, you better be prepared to spend some money!
6. Oil Cooler Lines
Oil cooler lines are another part that can be difficult to replace. These lines are vital to the engine’s operation, as they help keep the temperature of the oil from getting too high.
If one of these lines breaks or cracks, it can cause an oil leak, which can lead to serious engine damage.
The cost of replacing this line can be anywhere from $400 to $600, depending on which vehicle you drive and its age.
7. Clutch
The clutch is the part of your car that connects the engine to the gearbox. If your car needs a clutch replacement, you’ll need a professional mechanic. This is because the clutch is one of the most complicated parts of your vehicle. It’s also one of the most important — so if it breaks down on the road, you could be in trouble.
In addition, it can cost you up to $1000, including labor, which makes it an expensive car part to replace.
8. Engine
The engine is the heart of any vehicle, so it’s no surprise that replacing it can be tough. A new engine usually requires a complete reassembly of all the other components in your car or truck, which takes time and effort.
Even if you’re just looking to replace a small part like the timing belt or spark plugs, it will cost hundreds of dollars because the job is difficult, and parts need to be ordered from multiple sources.
Depending on what kind of car you have, you could spend up to $4000 to change out an entire engine.
Keep Your Car Well-Maintained
As we’ve seen throughout this article, there are a lot of parts on your car that can fail and need replacement.
Some are more common than others, but no matter what happens to your car or how old it is, you’ll always want to ensure that you have access to a good mechanic for all the things that might break down or wear out over time. If your car is compatible with aftermarket parts, then relying on brands you can trust such as COBB Tuning can prevent headaches down the line. If the installation is tough now, you don’t want to keep replacing it for maintenance’s sake, so go for the best you can afford.
In addition, don’t forget to buy a suitable type of car insurance, so you can keep your car well-maintained.
