What are the symptoms of a damaged oil cooler in the new Jetta?

Symptoms of a damaged oil cooler include the fan not rotating, the presence of engine oil in the radiator, and excessively high gasoline temperature, all of which could indicate a faulty oil cooler. Common failures include: Blocked or ruptured pipes, overlapping and deformed cooling fins, and improperly adjusted pressure relief valves. After removing the oil cooler, it should be cleaned by filling the cooling pipes with kerosene and blowing them through with compressed air. Solutions: If there are signs of oil leakage at the oil cooler location or oil floating in the coolant reservoir, a significant amount of oil will appear in the coolant, and the oil level in the coolant will rise rapidly. A damaged oil cooler needs to be replaced, and a damaged seal should also be replaced, although the seal is cheaper than the oil cooler itself.

How to Deal with Foggy Windshield on Rainy Summer Days?

On rainy days, if the windshield fogs up, you can: open windows for ventilation, use heating to defog, use air conditioning to defog, or apply chemical agents. Here are some solutions for dealing with a foggy windshield on rainy days: 1. Open windows for ventilation: If the rain is light, just a drizzle, you can choose to open both the front and rear windows slightly, preferably in a diagonal pattern. This way, as the car moves, external air can circulate inside the car and exit through the rear window. 2. Heating to defog: If the rain is heavy, opening windows for ventilation isn't an option, so other methods must be used to remove the fog. Since the fog is on the windshield, using hot air to evaporate it directly is effective, though this method may worsen the fog initially for a few minutes, so it should be used when safe. 3. Air conditioning to defog: If the car is in motion, using heating to defog can be dangerous as it may obstruct vision. In this case, turning on the air conditioning to cool and defog is advisable. Since the fog is caused by temperature differences, lowering the interior temperature to match the outside temperature will prevent fog from forming.
