Low gas mileage; knocking noises; vehicle not starting; foul exhaust fumes; stalling; backfiring: If you notice these issues, your Toyota Corolla engine may need some attention. In many cases, the check engine light comes on to indicate that there is a problem, but that should not be a sole determining factor. You need to know what to look and listen for to catch small problems before they become major headaches. Engine parts are obviously less expensive than an entire engine, so you really want to learn about your engine. Starting with the 95 Toyota Corolla engine, the manufacturer incorporated aluminum cylinder heads and an aluminum engine block to reduce the overall weight. Newer hybrid versions, including the Corolla Fielder and the Corolla Axio, started in 2012. Axio hybrids have 1.5-liter and 1.3-liter engines with four cylinders. Fielder hybrids have 1.8-liter and 1.5-liter four-cylinder engines. The 1.5-liter hybrid systems in both vehicles are similar to the one used in the Toyota Prius hybrid, but they are typically not interchangeable. Ultimately, the key to having a Toyota Corolla engine that lasts as long as it should is to ensure you have the correct engine for your exact year and model.
