Engine

NOTE: This information contains steps and procedures that may not be specific to your engine.

This information covers general procedures and diagnosis and testing of the engine system, except for exhaust emission control devices, which are covered in Powertrain Management.

The engine incorporates the following features:
^ a closed positive crankcase ventilation (PCV) system.
^ an exhaust emission control system.
^ an evaporative emission control system.

Some engines incorporate a fail-safe cooling system.

The engine, fuel system, ignition system, emissions system and exhaust system all affect exhaust emission levels and must be maintained according to the maintenance schedule.

Correct engine identification is required to order parts.
