How to Troubleshoot Your Volkswagen Jetta Water Outlet Problems
Your Volkswagen Jetta water outlet connects the lower radiator hose to the engine. It is usually made from aluminum, steel, or thermal plastic to ensure durability. However, this part would also wear out after years of use since it is exposed to the coolant, which could contain dirt and other damaging substances. Eventually, the water outlet, among others, would succumb to corrosion. When this happens, you might experience various problems that could be due to a damaged Volkswagen Jetta water outlet. Here's how you can diagnose them:
You may not know, but your coolant may be contaminated when a certain part of the reservoir or other components corrode. When this happens, the transported coolant will most likely bring along debris as it flows through the oil lines. This could bring about clogged lines and cause engine overheating. What you can do is to check the water outlet if it has signs of wearing out or rusting. Replace it immediately to avoid coolant contamination.
If lately you have been seeing a puddle forming underneath your Jetta, then that must be some of your coolant. A leaking water outlet could be the culprit behind this. Inspect your water outlet for any damage or corrosion. If there is a crack, put a thick bead of sealant into it. If there are rust spots, sand if off and then apply some sealant. Let it dry for about 20 minutes before installing it. This is only a temporary fix as the sealant could always wear out. Replace a damaged or rusted outlet with a new one to avoid leaks.
The water outlet has holes and ports for the sensors and switches. They are also made from aluminum, steel, or thermal plastic as they should be durable enough to connect with other components. However, it is inevitable that they would wear out. If the ports get cracked or broken, there would be a problem with the sensors and switches they are connected to. Conduct regular visual inspection to check on these parts to ensure that they won't cause problems that could greatly jeopardize the vehicle.
