The 2.4-liter 16-valve Chrysler EDZ engine was produced in Mexico from 1995 to 2010 and was installed on many popular models of the company, such as Cirrus, Sebring, Stratus, PT Cruiser.
The Neon series also includes internal combustion engines: EBD, ECB, ECC, ECH, EDT and EDV.
In 1995, a 2.4-liter engine appeared in the Dodge and Plymouth compact car engine line. By design, this is the most common gasoline engine with distributed fuel injection, a thin-walled cast iron block, an aluminum 16-valve head with hydraulic compensators, a timing belt drive and a dual-coil ignition system that was current at that time. A feature of this power unit was the presence of a block of balance shafts in the pan.
From 1996 to 2000, the Mexican market offered a turbo version of the engine with 170 hp and 293 Nm. Such an engine was installed on charged modifications of the Dodge Stratus R/T or Cirrus R/T.

Disadvantages of the EDZ engine
- This motor absolutely does not tolerate overheating, and its thermostat regularly flows through the body. So replacing the gasket with grinding the mating surfaces is not a rare procedure;
- Another common problem is burnout of one or more exhaust valves. The cause is usually oil soot on the plate or worn guide bushing;
- Quite a lot of trouble in this power unit is caused by an electrician: the crankshaft and camshaft position sensors fail, and the lubricant pressure sensor often flows;
- Also online, they constantly complain about malfunctions in the operation of the gasoline vapor recovery system, and also about the modest resource of engine mounts, high-voltage wires and the chain of the balancer unit.
