Where is the vehicle radiator located?

Vehicle radiators are positioned in front of the engine, directly behind the wind-facing grille at the front of the car (except for rear-engine configurations). They consist of an upper tank, lower tank, cooling tubes, and cooling fins surrounding the tubes. The engine's water pump circulates hot coolant into the upper tank, which then flows through the cooling tubes to be cooled before entering the lower tank and recirculating through the engine. Commonly called "radiators," their technical name is coolant heat exchangers. Coolant is typically added directly to the upper tank. However, vehicles with large-capacity cooling systems (such as premium coaches and cab-over-engine trucks) often feature an additional auxiliary tank (also called an expansion tank) - usually a plastic reservoir connected to the radiator's upper tank. This secondary tank serves two purposes: providing convenient coolant filling access and accommodating coolant expansion/contraction during temperature fluctuations.
I've been driving for over a decade, and the coolant reservoir is typically located at the front of the engine bay—just pop the hood and you'll spot it. It's usually positioned right next to the radiator, a plastic container that stores coolant to prevent engine overheating. Every time I perform a vehicle check, the first thing I do is inspect the coolant level to ensure it's between the minimum and maximum marks. If the level is too low, cooling efficiency drops, which could lead to engine damage from overheating. When locating it, be careful not to mistake other reservoirs near the steering wheel. Always use dedicated antifreeze instead of water when topping up. Remember to check when the engine is cold to avoid burns. The placement is quite user-friendly, making maintenance straightforward and convenient.
