The coolant reservoir in an older Jetta is located in the engine compartment. Below is some relevant information about the older Jetta: 1.

The Jetta sedan not only pioneered the application of high-end engine technology and safety equipment in mid-range cars but also was the first to adopt advanced multi-point fuel injection technology and was equipped with a three-way catalytic converter across all models. 2. Model Introduction: Jetta is an automobile brand of the German Volkswagen Group. The Jetta was launched in Europe in 1979. Structurally, the Jetta is essentially a Golf with a trunk added, making the Jetta a derivative of the Golf.
I've been driving an old Jetta for many years, and adding water is quite straightforward. Look for the transparent plastic tank in the engine compartment, usually labeled 'Coolant' or 'Kühlmittel,' located on the right side or the front left corner, near the battery or radiator. In older models, it has a round cap that's easy to unscrew. Always wait for the engine to cool completely before adding water, or hot liquid may spray out and cause burns; use professional coolant mixed with distilled water, ideally in a 50/50 ratio. Avoid adding pure tap water or mineral water, as it can cause scaling and damage the cooling system. Check that the fluid level is between the high and low marks—overfilling can lead to overflow and corrode parts. I remember once neglecting to check, and the overheating warning light came on when driving uphill. Regularly adding water and maintenance can prevent major engine issues, especially since older cars are more prone to aging and leaks.
