While incredibly robust, the 2SZ-FE exhibits a few predictable issues as it ages past the 150,000 km mark. 1. Rough Idling or Engine Stalling
When replacing the timing chain, you must use Threadlocker 242 on the camshaft sprocket bolts. Untreated bolts back out and destroy the cylinder head in 5,000 miles. Standard valve clearances (measured cold) must be checked
Manual models are easier to service and lack the complex maintenance requirements of CVT systems. Maintenance and Common Issues
Unstable idling speed, dipping below 600 RPM, or stalling when coming to a stop. | | | Step 2: +90° | Step
Position the camshafts so the timing marks on the VVT-i controller (intake) and the exhaust camshaft sprocket face each other horizontally, aligning with the cylinder head mating surface.
