Best Radiator For Jeep [XJ/TJ/JK/Liberty]: Buying Facts
At this point, it’s quite evident that the radiator plays a critical role in the engine’s cooling system.
Not all manufacturer radiators have what it takes to keep up with high-performance cooling needs.
At times, the responsibility of finding and installing the best radiator for Jeep falls on the car user.
Whether the goal is to add horsepower or simply swap an older version for a newer one, here are some crucial points to consider when purchasing a radiator.
Ease of Installation
One of the important things is the process of radiator replacement and installation. this great video helps you a lot.
Material
Different types of metals and even plastic are common primary elements in making car radiators.
Plastic is often the cheaper version, but it is also more prone to crack earlier than radiators made from other materials because of the continuous expansion and retraction.
It might sound like a clear disadvantage compared to metal, but the user doesn’t risk rust contaminating the coolant.
Right now, aluminum radiators are the most dependable kinds.
They’re not susceptible to rust like other metals, they don’t expand quickly, and they’re incredibly sturdy.
Radiator fans
Many radiator designs are now opting for an electrical fan because they are more energy-efficient.
However, it possible that there are a couple of models that still have mechanical fans.
With an electrical fan, your engine’s system can save up to twenty horsepowers.
So when choosing to go with a more modern fan, unless there are other advantages the mechanical ones have.
Restriction of coolant
Engines generate a lot of heat, and it’s necessary to cool them down.
The radiator doesn’t cool the motor directly; instead, it removes heat from the antifreeze going through the vehicle’s system.
So if there’s any restriction or blockage in the design, then the radiator is as good as useless since it won’t function.
Inspect the tubes thoroughly; the broader and cleaner they are, the better.
Wide pipes increase the surface area of fluid available for cooling, making the radiator’s job more comfortable and efficient.
Cost
Before buying anything, including a budget of radiators, you must have a plan in mind.
Knowing how much you’re willing to spend can help narrow down the choices you have to make.
Moreover, a low budget doesn’t necessarily mean compromising on quality.
It’s still possible to find something that fits your needs and fits nicely within the financial plan.
The mount
Factory radiators will often mount to the radiator support via padded saddles or rubber grommets.
The essence of this type of mounting is to protect the radiator from excessive external shock and vibration.
The kind of protection the fittings offer can prolong the radiator’s lifespan, so it’s crucial to find one that fits properly.
Designs that are compatible with all the OEM mounting provisions are a serious plus.
Coolant flow
Alternatively known as the radiator layout, there are two main types of coolant flow: downflow and crossflow.
The downflow radiators have a header tank at the top and bottom of the core, and fluid passes vertically through the body.
On the other hand, crossflow radiators have tanks on the sides, so coolant runs across in a horizontal direction.
At times a vehicle can come with configurations or even switch between the two.
Either way, neither one has any advantage over the other. The sole difference is in the fitting, so make sure you get the right layout.
Core design
Popular terms with radiators are single and dual-pass core.
Unlike the coolant flow, the difference in the core design can affect the cooling system’s effectiveness.
In the first one, the single-pass, the antifreeze moves from one header tank to the other in a single direction.
A double pass radiator has a divider that often goes through the middle of the header tank.
The divide makes coolant run in one order, then back across separate parts of the core.
The double pass radiator can run as much as ten degrees cooler than a single pass core of the same size.
So it might be worth considering paying extra for a double pass radiator.
Number of rows
A significant consideration is the number of rows the radiator has.
The more rows there are, the higher the volume and efficiency in transferring hot air within the engine to the ambient air.
Most designs adopt either a two, three, or even four-row scheme.
But the downside of having more rows is that the radiator fan has to be more vital to disperse heat more effectively.
It could also require more mounts to accommodate the additional width.
Before purchasing, evaluate the electric fan’s state and how many rows the engine can accommodate.
Inlet and outlet location
Different engine designs place the coolant inlets and outlets in other locations, and in an engine swap, there’s always the question of whether they have the placement.
When they don’t, it’s necessary to get a different fitting. Specific cars can adopt AM style fittings that increase hose retention and make it easier to remove.
Many radiators use an automatic transmission application.
They often include an integral cooler built into the outlet header tank.
So a properly designed aftermarket radiator should consist of the right fittings to connect to the standard OEM style transmission.
The radiator cab
Although the cab is a small component of the radiator, it is also vital to consider.
It has two essential purposes: one being to allow the cooling system to pressurize as it heats up and increase the system’s overall efficiency.
The other primary function acts as a pressure relief valve to protect the radiator, hoses, and other parts from damage.
Some cab designs can drawback coolant from an overflow reservoir and re-use it, which helps to bleed trapped air from the system and improve performance.
Make it a point to inquire about the cab’s design and function to ensure everything is in place.
Best Radiator For Jeep Review: We Need To Know
What problems can a bad radiator cause?
A car’s radiator is an essential part of its cooling system. As a result, when one fails to get the best radiator for Jeep, it’s unsurprising when several complications pop up.
One of the most common telltale signs of a bad radiator is overheating.
Since the cooling system is compromised, the engine finds it hard to maintain a stable temperature and becomes excessively hot.
Another problem users encounter, especially those with an integrated transmission, is more difficult shifting.
The logic behind that is when there are leaks in the system; coolant can seep into your shifting fluid and create unwanted trouble.
Other common problems with a bad radiator are clogged exterior fins and malfunctioning heaters.
If you’re experiencing any of these problems, consider swapping out the old radiator for a newer, more effective model.
How do you tell if your radiator is clogged?
Over time, radiators can become clogged, creating a whole host of problems for the user.
The primary factor that leads to a clogged radiator is the rust that tends to accumulate as time passes.
Often a blockage prevents much-needed coolant from circulating properly, and it can leak into other parts of the engine or onto the floor.
Coolant contaminated rust might have a hard time spreading as well. That’s because the debris usually changes its thickness and color, making it darker and harder to flow.
If your water pump is experiencing problems, it could also point to a faulty cooling system.
A clogged radiator prevents coolant from flowing, and without it, there’s no lubrication.
In turn, the inadequate lubrication will put more pressure on the water pump and impair it.
How often do jeep radiators need to be replaced?
The recommended mileage for the average radiator is 80,000 miles.
It takes most jeeps anywhere from eight to ten years to cover that distance, but it could be more or less depending on the user.
Older models can remain functional throughout the entire lifespan of a car.
But they require a lot of maintenance to live that long.
The radiator is an integral part of the engine’s cooling system and keeps it from overheating, so it’s crucial to have one that operates at optimal efficiency at all times.
However, if the radiator starts showing signs of failure, don’t wait till it gets to the average benchmark.
Speak with a professional auto-mechanic about replacing it with a better model.
What causes a radiator to crack?
Newer models of radiators often use plastic as the primary material in their production.
Over time, the constant expansion and contraction effect caused by heating and cooling can cause the radiator to crack.
But that’s not a cause for concern until the ten-year mark. Still, other factors can cause it to burst before that mark as well.
Metal models are liable to cracking when they start to rust.
Extreme temperatures also make it harder for the radiator to keep the engine cool in a warmer climate, while colder weather can cause a burst if the fluid within the tank freezes.
If the thermostat is damaged, it can create scorching temperatures, and the increase in coolant pressure could also lead to a burst radiator.
What happens if you don’t flush coolant?
Part of maintaining a radiator involves flushing the coolant. Car owners ought to do so regularly to wash away any build-up within the radiator.
Failing to do so can result in unpleasant consequences like the engine overheating.
In extreme cases, drivers might hear a funny knocking sound coming from the engine, and in other cases, you might perceive a pungent odor coming from the bonnet.
As the antifreeze circulates through the jeep, over time, it picks up rust and other debris.
Frequently flushing the coolant can eliminate the unwanted particles and keep your car’s system running smoothly.
Ideally, it’s good to flush the radiator fluid annually; some people even do it more often.
Is it safe to drive a car with a bad radiator?
No, it’s not. It’s quite dangerous to continue driving a car when you know the radiator is bad.
A faulty radiator means the vehicle has no way of checking its temperature, and that is risky.
The longer the drive, the hotter the engine becomes, and when the radiator can’t cool it, overheating is inevitable.
Of course, when the engine overheats, the vehicle follows suit, and it can be uncomfortable to drive.
How do I temporarily fix a radiator leak?
Sometimes users discover a leak in their radiator, and when there isn’t enough money or time to take it to a mechanic, you could do a temporary fix.
Get the right safety equipment and wait for the engine to cool down before proceeding.
Then, wash the radiator with a hose to make it easier to spot the leak or crack’s exact location.
A pressure tester is a handy tool to help with precision.
After locating the leak, apply a commercial sealant and let it set—everyday food items like egg yolk and pepper suitable to fix cracks.
However, radiator epoxy is a useful temporary alternative.
How do I replace my radiator myself?
Replacing a car radiator is a lot of work, and it’s okay to seek the help of an auto-mechanic.
But if you insist on doing it, then you’ll need essential items like a jack, pliers, sockets, and of course, safety gloves.
Start by using the jack to raise the vehicle, so there’s more access to work.
Before initiating a change, drain the radiator fluid entirely and remove the reservoir hoses.
