As a seasoned mechanic with years of experience, I believe aligning the timing on the old 4G64 engine is an art that requires a step-by-step approach. First, lift the car securely with a jack—safety comes first. Then locate the timing marks: there's a small notch or scale on the crankshaft pulley that must align with the pointer on the front cover; the camshaft gear also has several marks, usually indicating the top dead center position of cylinder 1—you can remove the spark plug to confirm cylinder pressure. Next, loosen the belt tensioner bolt with a wrench, being careful not to let the belt slip off. Adjust the camshaft position until all marks align perfectly, then tighten the tensioner. Rotate the engine two full turns to check if the marks return to their original positions. This process demands patience—misalignment could damage valves or pistons, leading to costly repairs. I recommend keeping a repair manual handy or referring to online tutorial diagrams. Basic tools will suffice, but beginners are better off leaving it to a professional shop to avoid complications.
