If you're looking for a new forklift radiator coolant hose, you've come to the right place. Whether it's a lower radiator hose or an upper radiator hose, at Lift Parts Warehouse we've got you covered. A faulty radiator coolant hose can significantly compromise your forklift's engine; however, by simply replacing a radiator hose on time can save you a lot of unwanted costly repairs. With new coolant hoses, you will guarantee the proper functioning of your forklift's engine cooling system, allowing your material handling vehicle to always remain in its optimal temperature range.
The Best Radiator Hoses for Your Forklift
Forklift radiator hoses, also known as forklift radiator coolant hoses, are flexible rubber tubes that help carry the coolant fluid back and forth between the engine and radiator. That's why they're a vital part of the forklift cooling system. A radiator coolant hose has excellent resistance to handling high pressures and temperatures thanks to its rubber-material constitution.
Commonly forklifts powered by internal combustion engines rely on an upper radiator hose and a lower radiator hose, each with specific functionality. They work as follows:
Upper radiator hose: Its function is to receive the hot coolant from the engine black through a thermostat. The other extreme of the upper radiator hose is connected to the upper radiator tank, where the hot coolant is delivered. This radiator hose it's also known as "inlet radiator hose" or "inlet radiator coolant hose."
Lower radiator hose: This radiator hose connects the tank located at the bottom of the radiator with the water pump. Through this radiator hose, the coolant (with a low temperature) is pumped toward the engine body. This radiator coolant hose it's also known as "outlet radiator hose" or "outlet radiator coolant hose."
When buying new forklift radiator hoses, make sure you choose the right one. These forklift radiator coolant hose types are not interchangeable. An upper radiator hose and a lower radiator hose have different sizes and lengths.
Long Lasting Radiator Coolant Hoses
Radiator hoses are an important part of any forklift's cooling system, so it's important to have a quality product that provides long-lasting performance. The radiator hoses we stock are made from the highest quality materials and are designed to provide no less than five years of lifespan. We count on coolant hoses from all major brands of forklifts and models, so you can rest assured that you're getting a product that will work with your existing equipment.
However, it is important to remember that if any of the other parts of the cooling system fail, the lifespan of the radiator hose will be greatly reduced. This is especially true for the upper radiator hose. Lift Parts Warehouse only stocks radiator hoses that meet the highest quality criteria, so you can be sure you're getting a product that won't disappoint.
Let us Know Which Radiator Hose your Forklift Requires
What radiator hose do you need to replace? A forklift upper radiator hose has to deal with a higher temperature coolant and withstand higher pressure than a lower radiator hose. That's why both radiator coolant hoses differ in shape and dimensions. Commonly, the lower radiator hose has a wound wire spring to avoid collapsing.
Dimensions: The size of a forklift's radiator can vary depending on the model of the forklift. This means that coolant hoses, in terms of diameter and length, an upper radiator hose or a lower one can vary a lot between different models of lift trucks.
Type: According to its composition, radiator coolant hoses withstand different temperature ranges. The following table shows the main one.
Cooling system hoses type and relative parameters
Typical Temp. range (°C)
-55 to 175
-40 to 100
-40 to 100
-40 to 125
-40 to 125
-40 to 150
-40 to 125
Replace a Radiator Hose Before it's too Late
Identify where the radiator hoses are. Generally, they are bigger than the other hose types and have a specific shape.
Touch the hoses and squeeze them to check their condition. They must have a certain flexibility and springiness—a forklift radiator coolant hose that feels soft, weak, or brittle should be replaced immediately.
Check all coolant hose clamps. The coolant hose clamps should be replaced if you find them rusty. By doing this, you prevent leaks from forming at the radiator hose connection and improve its stability.
Easy to Install Forklift Radiator Hoses
Park the forklift on a level surface and turn off the engine. Allow the forklift to cool completely before beginning any work.
Locate the radiator hoses. There are two of them, a lower and an upper radiator hose.
Using a wrench, loosen the clamps that secure the radiator hoses to the fittings on the forklift. Be careful not to damage the hose or the fitting when loosening the clamp.
Once the clamps are loose, remove the old radiator hoses from the forklift. If necessary, clean any debris from the fittings before installing the new hoses.
Place the new radiator hoses and make sure that they are properly seated on the fittings.
Use the wrench to tighten the clamps and secure the hoses in place.
Start the engine and look for leak signs. If there are any, tighten the clamps until they stop.
Allow the engine to run for a few minutes to check that the temperature gauge is working properly.
Radiator Hoses to Keep your Forklift Going
Radiator hoses will inevitably wear out over time. Being constantly exposed to high temperature and pressure levels, the material from which they are made begins to lose its properties. The main vulnerabilities to which forklift radiator hoses are exposed are:
Heat. A forklift radiator hose can withstand specific temperature ranges, so if other elements of the cooling system fail, the engine's temperatures will be higher than usual. This will cause the inner walls of the coolant hose to lose thickness and tend to expand, creating cracks through which the coolant can leak.
Poor clamp installation. It is another reason why a radiator hose presents leakages—this tends to happen after installing a new radiator coolant hose while the engine remains hot.
A bad radiator cap. An upper radiator hose can collapse due to a vacuum caused by a faulty radiator cap. Under normal circumstances, the caps are provided with pressure-regulating valves. When the engine cools down, the pressure drops, creating a vacuum effect that can cause a radiator coolant hose to shrink if not counteracted.

The forklift coolant hoses are rubber tubes that permit the coolant to pass between the engine body and the radiator.
The upper and lower radiator hoses are not the same, so they are not interchangeable. The upper radiator hose receives the hot coolant from the engine; the lower-radiator hose delivers the coolant at a suitable temperature to circulate again in the engine body.
When choosing a radiator hose, you need to be sure to know what the defective hose is. Other important criteria are its type and dimensions.
By regularly checking the condition of your coolant hoses, you will know when it is the right time to replace them.
