Faults, repair of Z18XER/A18XER engine

The A18XER engine is the same Z18XER, but strangled to meet Euro-5 environmental standards, this is the same motor.
On the territory of South Korea produce the same engine under the name F18D4, for Chevrolet Cruze, Opel Mokka and other cars. The Z18XER engine replaced the Z18XE in 2005. It is a regular simple inline four with a 16 valve head. The diameter of the intake valves is 31.2 mm, and the exhaust valves are 27.5 mm. It has a variable valve timing system on both shafts. This is a good thing, but often the solenoid valves of the phasoregulator fail and the motor makes sounds similar to the diesel engine. Usually the valves are cleaned, and if there is no effect, they are replaced. Unlike the old GM motors, the 1.8 liter has a receiver with variable length, which gives additional advantages. The Z18XER motor uses a good durable timing belt with a replacement period of 150 thousand kilometers. In addition, no EGR system is used, which is a plus rather than a minus. The thermostat on Z18XER is not the most reliable thing and often asks for replacement before the mileage of 80 thousand km.

Once in 100.000 km it is necessary to adjust the valves, because there are no hydrocompensators on A18XER/Z18XER, the adjustment is made by selecting calibrated cups. Valve clearances on a cold engine: intake – 0.21-0.29 mm, exhaust 0.27-0.35 mm.

Ignition module on Z18XER, like the thermostat, does not live long and after 70-90 thousand kilometers of mileage asks for replacement. Is your engine ticking? Perhaps it is the ignition module, often the reason is saving on plugs and their untimely replacement.
In addition, leaks from the oil cooler on Z18XER/A18XER are common, do not be surprised and do not worry, the repair costs pennies.

Motor resource of A18XER engine is 200-250 thousand kilometers and strongly depends on operation. In general, when choosing between 1.6 A16XER and 1.8 A18XER, choose the latter, with the same diseases you get a more powerful and traction motor.
