timing mark engine 1zr Toyota Corolla 2014
#1ZR
The timing marks for the 1ZR and 2ZR engines in the Toyota Corolla can vary depending on the specific year and model of the vehicle. However, I can provide some general information that may be helpful.

For the 1ZR engine, the timing marks are typically located on the crankshaft pulley and the timing chain cover. The crankshaft pulley will usually have a notch or keyway that lines up with a mark on the timing chain cover when the engine is at top dead center (TDC) for cylinder 1. There may also be marks on the camshaft sprockets that line up with marks on the timing chain cover.

For the 2ZR engine, the timing marks are also typically located on the crankshaft pulley and the timing chain cover. However, some models may also have marks on the camshaft sprockets or timing chain guides. As with the 1ZR engine, the crankshaft pulley notch or keyway should line up with the TDC mark on the timing chain cover when the engine is at TDC for cylinder 1.

It's important to consult the specific service manual for your vehicle to ensure that you locate the correct timing marks and follow the proper procedure for setting the timing. If you're not comfortable or experienced with working on engines, it may be best to have a professional mechanic handle this task for you.
