How do you set timing gears on 4he1t?

To set the timing gears on a 4HE1T engine, first, ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the camshaft and crankshaft gears; the marks should be in line with the designated reference points on the engine. After confirming the alignment, securely tighten the bolts and rotate the engine by hand to double-check the timing has not shifted. Always consult the specific service manual for torque specifications and detailed procedures.
