* Engine: Oil leaks are common and can originate from the valve cover gasket, oil pan gasket, crankshaft seal (front or rear), or even a cracked oil pan. Coolant leaks can come from the water pump, radiator hoses, thermostat housing, or a cracked radiator.
* Transmission: Transmission fluid leaks can occur from the transmission pan gasket, axle seals, or a seal around the shift linkage.
* Power Steering: Leaks can stem from the power steering pump, hoses, or rack and pinion seals.
* Brake System: Brake fluid leaks can be from wheel cylinders, calipers, or the master cylinder.
* Windshield: Leaks around the windshield are relatively common, particularly if the car has seen any prior damage or age.
* Sunroof: If equipped, the sunroof drain tubes can clog and cause leaks inside the car.
* Weatherstripping: Worn weatherstripping around doors and windows can allow water to enter the vehicle.
To find the leak:
1. Inspect visually: Look for obvious signs of fluid dripping or pooling under the car. Note the color of the fluid (oil is usually brown or black, coolant is green or orange, transmission fluid is red, brake fluid is clear or light amber, power steering fluid is typically reddish).
2. Check the fluid levels: Check your engine oil, coolant, power steering fluid, brake fluid, and transmission fluid levels to see if any are low.
3. Clean the engine bay: Clean the engine bay thoroughly to remove any existing fluid, making it easier to spot new leaks. Then, run the engine for a short time and watch carefully for any leaks.
4. Professional Inspection: If you can't locate the leak, take your car to a mechanic for a proper diagnosis.
Without seeing the car, it's impossible to pinpoint the exact leak location. The above list provides the most likely culprits.
