Engine Overview and Common Failures

The weight of the J37A engine according to the catalog is 210 kg. The serial number of the J37A engine is located at the junction of the block and the gearbox. Engines of this family are known for their reliability and have no weak points. Due to the small oil volume in the system, it is necessary to carefully monitor its level. The timing belt has a lifespan of approximately 100,000 km, and if it breaks, it can bend the valves. The usual cause of fluctuating engine rpm is throttle contamination. Valve adjustment is required every 50,000 km, there are no hydraulic compensators.
