The Toyota Corolla is a brand of compact cars made by Toyota. If you have a 2003 Corolla, you own a Ninth generation E120 or E130. The vehicle is known for a spacious interior, feisty engine, and reliability. According to Edmunds.com, the 2003 Toyota Corolla will likely encounter moderate engine problems during ownership, including problems with the timing belt. If you need to change the timing belt on your Corolla, the job doesn't take very long.
Disconnect the positive battery cable and set it to the side. Chock the wheels to prevent the car from moving.
Remove any obstructions to the timing cover. There are a few parts that obstruct access to the timing belt cover, including the air intake assembly, water pump pulley, power steering pump and air conditioning compressor. Remove the parts and set them to the side.
Use a 10mm wrench to align the mark on the crankshaft pulley to zero on the timing scale. Remove the bolts from the timing belt cover and set it aside.
Place G clamps on the camshaft and crankshaft seals to prevent them from slipping. Align the timing belt pulley mark with the timing mark on the front of the engine. The timing mark on the engine is shaped like a "V."
Remove the old belt and put on the new belt. Make sure it directly covers the teeth of the timing sprockets.
Remove the G clamps and put the timing cover back on. Return all the parts that obstructed the timing cover back to their proper places. Plug the positive battery cable back in.
