Bolted Parts and Assemblies
Refers to items bolted to inner structures, radiator supports, cowl and dash, etc., that may need to be removed for access. Due to the variety of these items and vehicles, time to remove and install or replace them is not included. Refer to the specific Procedure Explanation for examples of these items.
Disconnect & Connect
Disconnect a part or assembly by unbolting and/or unplug, and set it aside without physically removing it from the vehicle to gain access or removal of an adjacent part. The disconnected part or assembly is then reconnected during the assembly process.
High Strength Steels
Complete HSS information is not available from the vehicle manufacturers. When information is available, the components will be called out by the appropriate acronym (HSS/UHSS etc.) within the text after the name of the part identified. See Abbreviations in Reference Information for a list of acronyms and their definitions.
New Undamaged Part
Refers to a replacement part from the vehicle manufacturer without exterior or interior trim or attached parts.
Overhaul (O/H)
Remove an assembly, disassemble, clean and visually inspect it, replace needed parts, reassemble and reinstall on the vehicle making any necessary adjustments. Items which can only be changed by using the overhaul operation are shown by placing "IOH" (Included in Overhaul) in the column. There are other items which are included in the overhaul operation that may be replaced individually. These will have a time assigned for a stand-alone operation. For verification, refer to the Procedure Explanation for the operation being performed.
Overlap
If adjoining parts are being replaced (example: quarter and rear body panels), there is an overlap in that both individual operations include common welded surfaces or parts attached to both panels. A deduction must, therefore, be made from the total of the individual operations to compensate for the two or more repeated operations in each sub-task. Similarly, if a part has already been removed, it makes access to other parts easier.
Remove and Install (R&I)
Remove a part or assembly, set it aside and reinstall it later. The time shown includes the alignment that can be done by shifting the part or assembly.
Remove and Replace (R&R)
Remove a part or assembly identified as included within the Procedure Explanation and replace the part or assembly with a new one. The time shown includes the alignment that can be done by shifting the part or assembly.
Underhood Dimensions
Engine compartment views are shown as if you are above the vehicle looking down. A centerline is provided for measuring strut widths. The illustration is an exact view of the engine compartment showing all bolts, holes, supports and other structural components. Measurements can be duplicated with tape measure or with tram bar pointers set at equal lengths. Dimensions are given, whether symmetrical or non-symmetrical. All round holes are measured to center. Oval holes are usually measured to the front or rear center. Measurements are shown in millimeters. These dimensions are for estimating purposes only. See Vehicle Dimension topic in the Mitchell Information Center.
Order by Application
Many parts vary in usage according to differences in colors, materials, engines, transmissions, VIN, year and other factors. Where there are occasional variations regarding the part price, a representative part number at times is selected and the phrase “Order By Application” is footnoted to the part’s description. Consult the dealer parts department for exact price and/or part number information.
