4th Generation VW Jetta Coolant Leaking

The Jetta manufactured from 1999 to 2005 was the 4th generation of this model, and the fact that it is still sold in many foreign countries testifies to its enduring popularity. This generation of Jetta has improved safety features, increased interior space and other improvements. However, some common problems are also appearing. Some owners experience a coolant leak in their Jetta.

The car itself will alert you when the coolant gets low. Leaking becomes apparent when the coolant light comes back on shortly after you fill the coolant reservoir. If there is a leak, you will likely spot coolant puddles underneath the vehicle after it stays parked for a while. Open up the hood. Do you see a candy-pink coating on any of the belts? How about around the coolant piping connections? All of this helps identify A) that a leak exists, and B) where it might be occurring.

Leaks are commonly caused by cracks in the coolant reservoir itself, or in the coolant lines. Sometimes the head gasket leaks the fluid, but this doesn’t usually occur until after the engine overheats (which is what happens when the cars run without coolant), and so is more likely a symptom of the problem rather than the cause.

While locating the site of a coolant leak may seem simple enough, mistaken diagnosis can lead to a destroyed engine due to overheating. Rather than risk ruining your car, take it to a trained Volkswagen service mechanic to have it repaired as quickly as possible. Further damage could result if this condition is ignored.

Search for a local, independent Volkswagen repair shop with Volkswagen mechanics that have dealer-level expertise at a fraction of the expense.
