The weight of the 4ZD1 engine according to the catalog is 150 kg. The engine number 4ZD1 is located at the junction of the block with the cylinder head. This is a simple, reliable, but very rare motor. Most of the problems with this engine are related to wear due to its age. Due to throttle body contamination, idle speed often fluctuates. The fuel pump and archaic ignition system also have a modest lifespan. It is necessary to adjust the valve clearances and replace the timing belt every 100,000 km.
