Replacement Engine - A replacement engine is defined as follows:

1. A new, rebuilt, remanufactured, or used engine of the same make, number of cylinders, and engine family as the original engine with the original emission controls reinstalled;

or

2. An engine which matches a configuration offered by the manufacturer for that year, make and model of vehicle, and the appropriate emission controls for the installed engine, and chassis components are present and connected.

Vehicles with "replacement engines" should be inspected by licensed smog check stations and not be sent to the state referee.

Example: A 1982 Chevrolet Camaro was originally equipped with a 3.8L engine. It now has a new 5.7L Chevrolet engine installed.

Action: The emission control systems application manual shows that a 1982 Camaro also came from the factory with a 5.7 L engine. The car has all the required emission control system installed for a 1982 Camar with a 5.7 L engine. The car would be tested by the technician as though the 5.7 L engine was factory installed.

All the required emission control equipment for a 1982 Camaro with a 5.7 L engine must be installed and connected.

Engine Changes

Section 3362.1 of Title 16 of the California code of Regulations states: "An Automotive Repair Dealer shall not make any motor vehicle engine change which degrades the effectiveness of a vehicle's emission control system. Nor shall said dealer, in the process of rebuilding the original engine or while installing a replacement engine, effect changes that would degrade the effectiveness of the original emission control system and/or components thereof."

An engine change is defined as follows:

An "engine change" is the installation of an engine that is different from the one which was originally installed in the vehicle and does not qualify as a "replacement engine."

The following ensures the provision of the CCR 3362.1 are met.

- The installed engine and emission controls (for an exhaust-controlled vehicle) must be the year of the vehicle or newer, and certified to the same or a more stringient new vehicle certification standard.

- Do not mix engine and vehicle classifications that degrade the emissions certification standards. For example, a heavy-duty engine cannot be installed in a light-duty exhaust controlled chassis even if they are the same displacement. non-emissions controlled power plants such as industrial or "off-road use only" engines may not be installed in any exhaust-controlled vehicle.

- The installed engine and host chassis must retain all of their original emission control equipment. Diesel to gasoline conversion must have all gasoline engine and chassis emission control systems installed.

- No internal or external engine modifications (cams, pistons, etc.) may be performed unless the parts/systems are ARB exempted or are EPA certified for use on the installed engine.

- If a computer-controlled engine is installed in a non-computerized vehicle, the MIL "Check Engine" light, OEM diagnostic link, and all sensors, switches, and wiring harnesses need to make the system fully functional must be installed. The computer control systems must operate correctly.

Example: A 1980 Datsun pickup was originally equipped with a 2.0 liter four-cylinder engine. it now has a V-6 engine installed from a 1993 Chevrolet S-10 pickup

Action: If the vehicle is equipped with a BAR Referee Label, Smog check stations can inspect the vehicle using the emission controls system information listed on the label.

If the vehicle does not have a BAR label, refer the customer to the BAR Referee. The referee will make a determination of the correct emission control equipment and install a corresponding BAR Referee Label. thereafter, a licensed Smog Check station can inspect the vehicle in accordance with the equipment listed on the label.
