High Priority (Consider doing ASAP):
* Timing Belt (and Water Pump): This is crucial for a 2001 Echo. These typically need replacement around 90,000 - 105,000 miles, depending on the specific engine. Since your car has 202,000 miles, it's overdue and a broken timing belt can cause catastrophic engine damage. The water pump is often replaced at the same time as it's labor-intensive to access.
* Serpentine Belt: This drives several accessories. Check its condition for cracking or fraying. Replacement is relatively inexpensive and prevents major problems down the line.
* Spark Plugs & Wires: These wear out with age and mileage, affecting performance, fuel efficiency, and emissions. Replacing them is a relatively straightforward maintenance task.
* Brake System Inspection: Have a thorough inspection of brake pads, rotors, calipers, and lines. Brake failure is a serious safety concern. Expect potential replacement of pads and possibly rotors.
* Fluids: Beyond the oil changes, ensure all other fluids are fresh and at the correct levels:
* Coolant: A crucial component preventing overheating. Consider a flush and refill, especially given the age and mileage.
* Transmission Fluid: Automatic or manual, this needs to be checked and possibly changed depending on its age and condition. Consult your owner's manual for the recommended service interval.
* Power Steering Fluid: Inspect and top off or replace as necessary.
* Brake Fluid: Highly hygroscopic (absorbs moisture), leading to brake failure. A flush and refill are recommended.
Medium Priority (Inspect and plan for replacement as needed):
* Suspension Components: Inspect for worn shocks, struts, bushings, ball joints, and tie rod ends. These affect handling and ride comfort. Worn components can be dangerous.
* Tires: Check the tread depth and overall condition. Worn tires compromise safety.
* Battery: The battery's lifespan is typically 3-5 years. Have it tested. A weak or failing battery can cause starting problems.
* Alternator & Starter: These components are essential for the car to run. Have them tested to check their health.
Low Priority (But eventually needed):
* Exhaust System: Inspect for rust and leaks. Eventually, parts may need replacing.
* Hoses and Belts: Check all hoses and belts for cracking or deterioration.
* Filters: Air filter, cabin air filter, fuel filter should be replaced on a regular schedule.
Recommendation:
Before driving the car extensively, I strongly recommend a thorough pre-purchase inspection by a qualified mechanic specializing in Toyota vehicles. This is especially important given the unknown maintenance history and high mileage. The cost of the inspection will be far less than the potential cost of major repairs later on. The mechanic can provide you with a detailed report outlining all necessary repairs and their urgency.
