Do you see puddles of some liquid under your car engine on the ground? Is your car overheating? Does your car stop on the highway sometimes? Is the air conditioning not working inside your car?
Oh no! These appear to be the symptoms shown by a car whose radiator has gone bad. What to do? Get your car to a mechanic immediately. A check by an expert mechanic could reveal either a minor or major concern. Perhaps it is just a loose clamp where the radiator hose goes to the coolant or another pipe. Perhaps it’s a worn-out hose. While minor concerns can be addressed easily, what about major ones?
We recommend a thorough check by the mechanic. May we caution you to replace the radiator even if it has a minor crack or leakage. Do not attempt to repair a cracked radiator. Why? Well, the answer is simple. Any repairs on important car parts like a radiator will not hold well for a long time. Cracks can reappear and damage your car further. Moreover, you don’t want to be spending time and money on getting to a mechanic again and again?
What Does a Radiator Do?
A radiator in your car is the cooling system for your ride. It maintains the coolant levels. A coolant is responsible for absorbing the heat from the engine as it passes over and under the engine to absorb all the heat from the engine. This prevents any overheating of a car engine. So, let’s get to select one of the best car radiators.

Things to Consider When Buying Best Radiator Replacement
Buying a vehicle radiator can be challenging unless you know the top points to consider. We recommend that you consider the following.
1. Stock or OEM
OEM replacements are good for a radiator. However, if you are determined to get a stock replacement, get details of your vehicle’s year of manufacture, model and make. You will need this when shopping online or approaching a car garage.
To upgrade to an aftermarket radiator, it’s important to understand your options. Increased power and high rpm require more cooling capacity. When searching online, consider the following:
In the yesteryears, copper or brass radiators were common. However, today most OEM radiators are made from aluminum. They are lighter, much stronger and less expensive. The best part about aluminum is that they do not rust. Additionally, aluminum radiators can host more rows for quicker heat dissipation compared to copper or brass.
Many would argue that copper is a better conductor of heat than aluminum. But they may forget that the purpose of a radiator is to release heat quickly, and hence the choice of aluminum is recommended.
Brass, on the other hand, is expensive. Brass is used more for holding the joints together in a copper radiator as copper isn’t a very strong material and often leaks faster.
However, if you would like to stick with a brass or copper radiator, you may have to shell out extra dollars.
Most radiators have large surfaces allowing the heat to disperse faster. If you have modified the engine or added power to your car, it will release more heat. You will need to get an enhanced radiator quality.
4. Number of rows and fins
Radiators have many tubes and fins to increase the surface area. When the coolant carries the heat is exposed to these fins, heat is released. Hence, you may need to check how many rows of fins are there. What is the kind of coolant tube size it can accommodate?
A radiator needs an external fan to keep the fins and other parts from getting heated up. Radiator fans are available either as a mechanical or electrical setup. The latest vehicles would seem to have an electrical fan. They are energy efficient and cause less trouble than mechanical ones.
Check for the strength and width of connecting tubes and hoses. You want to ensure that the coolant flow is not restricted. While installing, double-check that they have been tightly clamped to avoid losses.
Check that your vehicle has ample space to host a radiator of your choice. The engine bay has lots of wiring and equipment flowing through it. Since these are cramped areas, airflow gets restricted. Larger radiators will take more space and may not offer easy cooling. So go with the amount of space or an OEM replacement.
Basis the direction of fins, you have two types of radiators. The downflow has fins arranged vertically, while the crossflow has horizontal fins. Crossflow radiators are known to have a higher cooling efficiency. Older vehicles had downflow radiators, and hence their tubing flows will be different if you plan to fit a crossflow in the same place. So check this before you buy one.
Frequently Asked Questions
1. How do you identify a radiator crack?
One of the first things you will notice is that the temperature gauge on your dashboard starts going towards ‘H’ (Hot). This indicates that your vehicle is overheating. You may also notice that you have a sludge under your vehicle when it is in a parked position. This indicates that your car has some leakage; this will then need to be investigated.
The next step is to check open the hood and check for damages. It is critical to allow the radiator to cool down before you attempt to open it. Why? The radiator contains coolant coming from the engine, which is beyond its boiling point. This and more could be bubbling hot. Should you attempt to open the radiator when hot, you could burn yourself and cause an accident.
2. What causes a radiator to crack or leak?
Many things could prevent a radiator from working efficiently. The topmost factors include not topping up the coolant or changing the coolant after it has served its purpose; a bad thermostat; leaking seals, gaskets and pipes; loose clamps or cracked tubes causing the coolant to leak.
Know more about how you can fix a leaking radiator.
3. When to replace and not repair your vehicle’s radiator?
The most common thing is when your vehicle starts overheating, and the temperature gauge goes quickly to the H position. After replacing the coolant or topping it, if your vehicle is still overheating, you must check for more damages before replacement.
You will often see strong steam hissing out of the hood as the coolant is not serving its purpose. You may have missed adding ample coolant quantity or replacing it.
Coolant not topped-up or replaced
Ensure that you keep topping up the coolant in your vehicle. If it runs dry, this also could cause your car to release steam. Faulty radiator sealers or gaskets or those not tightened from the previous service could also be possible causes.
When not changed, overused coolants will change consistency from regular easy flowing to thick and viscous. This shows the need for a replacement.
Discoloration of radiator or sludge deposits
Check for deposits under your vehicle to check for leaks or any sludge deposits. Often a leaky radiator could leave a radiator discolored, indicating the need for attention to your radiator.
If you notice your car’s air conditioning or heating not working correctly, it could be due to your vehicle’s radiator issues.
4. When should you consider a radiator replacement?
In two main situations, really. Firstly, if you have a faulty radiator that requires more costs and attention or is beyond repairs, you will need a replacement.
Secondly, most people overlook if you have upgraded your vehicle’s engine to get more power. As the power output increases, the engine produces more heat than earlier. Not replacing the radiator kills heat output efficiencies, which could malfunction very soon.
5. Is it safe to drive a vehicle with a bad radiator?
No! Certainly not! If you press onwards for your journey with a faulty radiator, you are bound to be stranded as it could give up on you at any time. Don’t be surprised that you will not restart the engine, as cooling the radiator could take some time. Piping hot radiators could also burst open and cause damages to the engine and anyone under the vehicle’s hood.
6. Could I replace a radiator by myself?
Well, it certainly is your choice. If you are mechanically inclined, perhaps you should go ahead. If not, we recommend that you use the services of an expert mechanic. Radiators could be tricky if you leave any detail. You could take longer and yet not be able to install it correctly.
Using the services of an expert ensures correct installation troubleshooting while replacing and ensures safety for you and your loved ones.
7. How often does the coolant need replacement?
Most service manuals will have the time listed for your ease. A lot also depends upon your usage and if you stay in a hot and humid zone, necessitating air conditioning more often. We recommend that you keep a check on coolant topping as it gets consumed. As explained earlier, don’t miss replacing the coolant once it turns murky and thick. Thick liquids do not flow easily.
To sum up, a radiator is one of the main parts of your vehicle. Never take a chance of getting stranded for help with a cracked radiator or a leaky one. Replacement radiators are available in plenty. Make your wise decision in choosing one that fits your requirement and your budget the best. Look for brazen ones with a magnetic radiator cap and the best quality seals to prevent the coolant from leaking. Remember that the lighter the radiator, the lighter and easier your drive. Safe trips!
