Radiator Coolant Reservoir Cap
A bad cap can cause your car to overheat. This replacement cap is a cheap and easy fix for that problem.
It holds the right pressure in your cooling system, which raises the boiling point of the coolant. This one is made to the factory specs so it works just like the original. It fits a wide range of Elantras from 2013 to 2020.
Replacing a worn-out cap can stop coolant loss and prevent overheating. It’s one of the first things you should check if your temperature gauge acts up. This is a simple part that does a big job.

A-Premium Engine Coolant Radiator Assembly
This is a complete radiator swap for when yours is damaged or leaking. It’s a big job but this part makes it right.

AUTO DN Lower Radiator Coolant Hose
This lower radiator hose carries coolant back to the engine. If it’s soft, bulging, or leaking, you need a new one.
The hose is made from reinforced rubber to handle heat and pressure. It’s shaped to fit perfectly on older 1996-2000 Elantra models. Replacing a worn hose is a good way to avoid being stranded on the road.
It’s a single hose, so make sure you know which one is failing. The lower hose often sees more wear because of its location. This is a simple part that is vital for a healthy cooling system.
Pros:
👍 Reinforced rubber for long life
👍 Correct shape for a direct fit
👍 Prevents roadside breakdowns
👍 Affordable maintenance part
👍 Fits specific older Elantras
Cons:
👎 Only for 1996-2000 models

My Honest Opinion:

Cons:

If your A/C doesn’t blow cold at a stoplight, a bad fan
