How to Add Coolant to a 1998 Jetta

by Tara Kimball

If your 1998 Volkswagen Jetta is low on coolant, you should add coolant to it right away. When the engine temperature runs high, you risk damage to the internal components and potentially a blown head gasket. Volkswagen recommends using a 50/50 blend of antifreeze with pure, clean water. This prevents the water from freezing and cuts the glycol in the antifreeze so that it does not gel at high temperatures.


Allow the engine of your Jetta to cool completely before you attempt to add coolant. Open the hood of your car and prop the hood on the support rod.


Locate the coolant reservoir tank on the driver's side of the engine compartment, near the firewall. Check the coolant level on the reservoir tank. If the level is below the “FULL” mark, you should add coolant.


Remove the cover from the coolant reservoir tank. The Jetta coolant reservoir cover should pull straight up off the tank.


Add a mixture of 1/2 antifreeze and 1/2 fresh, clean water to the coolant reservoir tank on your Jetta until the level reaches the “FULL” mark. Cover the reservoir tank and run the engine for five minutes.


Check the coolant level and top it off again if necessary. Repeat the process until the reservoir level remains at the “FULL” mark. Close the hood of your Jetta securely after filling the coolant.
