How Do I Know If My Jeep Grand Cherokee Has HD Cooling?
A Jeep Grand Cherokee Hd Cooler is a heat exchanger that assists your automobile in transmitting heat from one medium to another.
As well as an oil cooler, the HD cooling system contains a special cooling fan and clutch.
A radiator or cooling fan has wide application in the automobile industry. If you’re having trouble locating your HD cooling, this article helps outline how you can identify HD cooling in a Jeep Grand Cherokee.
You can identify if your Jeep Grand Cherokee has HD cooling systems. First, you’ve got a big-duty radiator if the core is greater than 2 inches thick from front to back. To confirm this, lift the hood and inspect the grill. An intercooler, fluid for the steering column, and coolant for the engine are among the vehicle’s six cooling systems.
How Do I Know if I Have HD Cooling?
To check your HD cooling system, open the bonnet of your vehicle and look close to your radiator.
So, close to the radiator, you should notice that the cooler is attached with a valve that leads straight to the engine and radiator.
The HD cooling system comes standard in a Jeep Grand Cherokee. However, if you did not see any on your automobile, you can check your dealer or mechanic to get it fixed.
Another way to know if your automobile has an HD cooler is by taking your VIN to your dealer to check through your build sheet if your automobile came with a cooler.
What Is an HD Cooling Package?
When it comes to cooling down the power electronics on a vehicle, the Heavy Duty Cooling Package (HDCP) provides a complete thermal system solution.
The HDCP can cool succession of component inverters and converters using a variety of flow arrangements.
The cooling system is an essential feature of an IC engine because it prevents overheating during combustion.
The cooling system keeps the engine running efficiently by ensuring that the engine parts don’t overheat, which can cause a lot of damage to the engine.
The cooling system uses a heat transfer technique to keep the engine at the correct operating temperature.
Coolants come designed to withstand extremely high temperatures, preserving heavy-duty engines from damage.
In addition, it keeps the engine from freezing or burning out by transferring heat efficiently.
That will diminish the engine’s lifespan and efficiency if it does not have an effective cooling mechanism.

Pros and Cons of HD Cooling
Some people encounter issues with their cooling systems because of a lack of attention. Others are the result of adjustments.
You can use maintenance to treat neglect and discover remedies elsewhere.
Cooling system upgrades are commonly required to stay up with engine and vehicle performance adjustments.
An engine’s heating value is the time it takes for a certain amount of heat to transform into work.
However, it’s important to know that while I recommend HD cooling, it also has some downsides.
Below are the advantages and disadvantages of a cooling system:
#1. Advantages
- An oil cooler with a thermostat keeps the oil temperature at an accurate level.
- It guarantees that the oil is properly cooled before you may circulate it.
- The oil-to-water cooler regulates the temperature of the oil.
- Oil coolers are simple to set up.
- Oil coolers, in general, improve the performance of an engine.
- Due to the corrosive nature of the engine’s water cooling system, it reduces its utilization.
- Because oil is a significant part of the cooling system, the engine doesn’t require any additional coolant tanks, pumps, or radiators.
- The oil circulates in a controlled and efficient manner.
#2. Disadvantages
- Oil, in contrast to water, maybe combustible itself. So the oil cooler operation needs the use of more oil.
- A lot of extra work is required.
- If the thermostat is permanently locked, it will stop the oil flow.
- Leaving the valve open all the time can lead to overheating.
Functions of Coolant in Heavy-Duty Engines?
Because water isn’t adequate, coolants are employed. Water is rendered ineffective by its characteristics which causes it to boil and evaporate at high temperatures while freezing at low ones.
Coolants come equipped to withstand extremely high temperatures, saving heavy-duty engines from damage.
A lack of adequate heat transfer would cause the engine to freeze or explode. In addition, the anti-corrosion feature of the coolants prevents the corrosion and oxidation of the engine’s metal components.
The engine’s lifespan and performance will shorten if it is not equipped with an effective cooling system.
Coolant Types
Depending on the application and usage, there are at least three types of coolants used in heavy-duty vehicle engines.
In that order:
#1. Traditional Coolant
Metals such as steel, aluminum, and copper are protected against corrosion by these standard or conventional coolants.
This coolant in heavy-duty engines well protects wet sleeve liner corrosion.
However, the coolant’s corrosion inhibitors degrade quickly; therefore, their usefulness is constrained.
#2. OAT Coolant
They are silicate-free and have a long life expectancy, OAT or Organic Acid Technology coolants.
In addition, the carboxylate acid corrosion inhibitors in them have very low depletion rates, unlike the usual coolants.
As a result, Supplemental Coolant Additives do not need regular refilling, and you can often utilize one throughout the engine’s life.
#3. Hybrid Coolant
Using this coolant technology, you get the best of both worlds: traditional corrosion inhibitors and OAT corrosion inhibitors. Yellow and red are the most common colors of this coolant.
Both light and heavy-duty diesel engines can benefit from using these components. HOAT technology is another name for this hybrid technology.
How to Identify a Bad or Faulty Oil Cooler?
The following procedures are ways to know if your oil cooler is bad or faulty:
#1. Oil Cooler Adapter Leakage
There may be two oil cooler adapters in the system. On the other hand, it returns cooled oil to the pan.
If the oil cooler adaptor fails externally, the engine oil may be sucked out of the engine and spilled.
Small leaks between the adapter may cause an oil puddle at the engine’s bottom if the driver does not detect them. There’s a chance you’ll catch a glimpse of an oil slick trailing behind the vehicle.
If you see any oil leaking from your engine, you should have it checked out by a specialist. Then, the issue can be immediately identified and fixed.
#2. The Cooling System Has Oil
You’ll notice that the pressure in the oil is higher than the cooling system force if the oil in the cooler adapter is faulty.
As a result, the engine’s cooling system becomes less lubricated since the oil is driven into the cooling system as the engine runs.
If you don’t take precautions, this condition could do a lot of damage to your engine.
#3. Excessive Coolant Leakage
This failure is similar to the first in that it causes the engine coolant to be expelled from the engine.
So again, overheating will occur if the problem is not resolved, regardless of how tiny or huge the leak is.
You’ll notice a stream of oil coming out of the vehicle’s hood if the leak is large enough. Mechanics should be contacted as soon as possible in this circumstance as well.
#4. Cooling Agent in the Oil
This problem occurs when the engine is off, and the cooling system is under pressure. As a result, the coolant can move into the oil pan.
The crankshaft slaps the oil as it turns, causing damage to the engine.
#5. Thermostat Failure
Engine overheating or undercooling might be the result of a malfunctioning thermostat. The oil cooler’s thermostat regulates oil flow by opening when the oil reaches a predetermined temperature.
Overheating can occur if the thermostat malfunctions just before it’s set because oil circulation eventually stops.
A thermostat failure in an open thermostat causes undercooling since the oil can absorb no heat.

Summary
This article has explained the advantages and disadvantages of having a cooling system in your automobile and how to know if it’s faulty.
Although the cooling system helps a vehicle’s lifespan, it also helps regulate overheating in the engine by providing escape routes where heat can pass out to avoid further damage to your automobile.
