Common Causes & Issues
Worn Gaskets and Seals
Very CommonAge, heat, and mileage cause gaskets and seals to deteriorate, creating leak paths. Most common in vehicles over 5 years old or with 60,000+ miles.
Damaged Oil Pan or Transmission Pan
CommonRoad debris impacts, speed bump damage, or over-tightened drain plugs can damage pans and cause leaks. Often starts as seepage before becoming active leak.
Corroded or Damaged Lines
CommonBrake lines, transmission cooler lines, and power steering lines corrode over time, especially in areas with road salt or coastal moisture.
Failed Water Pump
CommonWater pump seals fail around 60,000-100,000 miles, causing coolant leaks. Often accompanied by overheating or bearing noise.
Cracked Radiator or Hoses
CommonPlastic radiator tanks crack with age, rubber hoses deteriorate from heat cycles. Usually visible at connection points or seams.
Loose or Missing Drain Plugs
UncommonImproperly installed or cross-threaded drain plugs from recent service. Can cause sudden, major fluid loss.
Our Diagnostic Process
Visual Fluid Identification
Identify leak type by color, texture, smell, and location under vehicle. Place cardboard under car to map leak points.
Lift Vehicle Inspection
Safely raise vehicle to inspect undercarriage, trace leak source, check all fluid levels and examine components for damage.
System Pressure Testing
Pressurize cooling system, test brake hydraulics, check transmission cooler lines to identify leak points under operating pressure.
Component Inspection
Detailed examination of suspected components including gaskets, seals, hoses, and hard parts for cracks or damage.
Leak Source Verification
Clean area and run engine to confirm exact leak source. May use UV dye for hard-to-find leaks.
Repair Options & Solutions
Gasket/Seal Replacement
Replace failed gaskets or seals. Cost varies by location and accessibility.
Hose Replacement
Replace deteriorated coolant, brake, or fluid hoses with OEM-quality parts.
Pan Gasket Service
Remove pan, clean surfaces, install new gasket, refill and test.
Line Replacement
Replace corroded or damaged metal lines (brake, fuel, transmission cooler).
Major Component Repair
Water pump, radiator, or steering rack replacement for major leaks.
Stop-Leak Treatment
Temporary solution for minor seepage - not recommended for active leaks.

Frequently Asked Questions
Is it safe to drive with a fluid leak?
It depends on the fluid and severity. Brake fluid leaks require immediate attention - don't drive. Small oil or coolant leaks may be safe for short distances if you monitor levels. Transmission leaks risk major damage. When in doubt, have it towed to prevent costly damage or dangerous situations.
How much does it cost to fix a fluid leak?
Costs vary widely depending on the type and severity of the leak. Simple fixes like tightening a loose drain plug are very affordable, while major repairs require more investment. Most common leaks (gaskets, seals, hoses) are competitively priced. We provide free inspections and detailed estimates before any work begins, so you'll know exactly what to expect.
Why is my car leaking fluid but not overheating?
You might have a slow coolant leak that hasn't depleted levels enough to cause overheating, or the leak could be another fluid entirely. Oil, transmission fluid, and power steering fluid leaks won't cause overheating. Have it inspected to identify the source and prevent potential damage.
Can I just keep adding fluid instead of fixing the leak?
While topping off fluids is a temporary measure, it's not a solution. Continued leaking can damage other components, harm the environment, and leave you stranded. Plus, constantly buying fluid often costs more than the repair itself over time.
How long does it take to fix a fluid leak?
Simple repairs like hose replacements can be done in 1-2 hours. Gasket replacements typically take 2-4 hours. Major repairs requiring component removal (transmission pan, head gasket) may take 1-2 days. We provide accurate time estimates after inspection.
What color fluid is most dangerous to leak?
Clear to brown brake fluid is the most immediately dangerous as it affects your ability to stop. Red transmission fluid and green coolant are also critical as they can cause sudden vehicle failure. Any fluid leak should be addressed, but brake fluid requires immediate attention.
