If you drive a 1999–2003 Toyota Camry, Highlander, or Lexus RX300 with the IMZ-FE 3.0L FWD V6 engine , you already know the reliability and performance these vehicles offer. With proper maintenance, these V6 engines, which are renowned for their smooth ride and sturdy construction, may survive for hundreds of thousands of miles.
At BS Auto Supplies, we specialize in parts and guidance tailored for older Toyota and Lexus models. Whether you’re a seasoned DIYer or a new owner of one of these classics, following the right maintenance practices is essential to prolong engine life and maintain performance.
1. Regular Oil Changes Are Non-Negotiable
The Toyota Camry 1999–2003 3.0L engine and its siblings in the Highlander and Lexus RX300 1999–2003 V6 engine lineup rely heavily on consistent oil lubrication. These engines tend to generate heat, and failing to change your oil every 3,000–5,000 miles can lead to sludge buildup—one of the most common problems for the IMZ-FE engine.
Use high-quality synthetic oil, and don’t skip the oil filter replacement.
2. Timing Belt & Water Pump Replacement
The IMZ-FE engine uses a timing belt, not a chain. Toyota recommends replacing the timing belt every 90,000 to 100,000 miles. While you're at it, it's smart to also replace the water pump, as both components share the same labor cost.
Ignoring this service could lead to catastrophic engine failure—a risk not worth taking.
3. Inspect and Replace Valve Cover Gaskets
The frequency of valve cover gasket leaks increases with the age of these cars. It's probably a leaking gasket if you smell burning oil or see oil seeping. Replacing this early prevents oil from dripping onto the exhaust and damaging other components.
BS Auto Supplies carries OEM-quality gaskets specifically for your Toyota Camry V6 engine and Lexus RX300 IMZ-FE engine replacement needs.
4. Keep an Eye on the Cooling System
The 3.0L V6 engine runs hot, especially during summer. Flushing and refilling the coolant every 2–3 years can prevent overheating and corrosion in the radiator. Check the radiator, hoses, and thermostat for wear. One of this powertrain's worst foes is overheating.
5. Use Quality Replacement Parts
Don’t skimp on quality when replacing engine components. Whether it’s spark plugs, ignition coils, oxygen sensors, or even an IMZ-FE engine replacement, trust reliable suppliers like BS Auto Supplies for high-grade, compatible parts that fit right the first time.
We offer parts specifically built for:
- Toyota Camry 1999–2003 3.0L engine

6. Transmission Fluid & Filter Maintenance
Many owners overlook transmission fluid service. Changing the fluid and filter every 60,000–80,000 miles ensures smoother shifts and extends the life of your transmission, especially on aging FWD models.
