This specification covers hose for use with either automatic transmission fluid or engine oil.

Material Description. Materials covered by this specification are divided into two sets of constructions and categories. The "Construction" of hose defines both the material content and construction of the hose. The "Category" of the hose defines the fluid with which it has been qualified for service. The hose is therefore defined as "GMW16171 Type XYZ," where "X" refers to the construction of the hose, and the "YZ" refers to the category to which the hose has been qualified for service. Thus, the material "Type" is defined by a combination of its Construction and Category. It is possible for a hose to be approved to more than one Type.

Construction: The "Construction" of hose defines the material content and construction of the hose. All hoses shall have a reinforcement of textile braid. Hoses shall be black. The hoses and/or hose assemblies are capable of giving satisfactory service in an automobile from temperatures of -40°C to the continuous and excursion temperatures shown for the respective construction.

The descriptions of the constructions of hose used for this application are as follows:

Construction A. This hose consists of a smooth bore tube of chlorinated polyethylene (CM) compound, resistant to Dexron VI (9986153) and/or engine oil (GME L0004, 93165209), dependent on the Category of the hose, which is reinforced with aramid braid, and has a cover of CM compound. The hose and/or hose assembly is capable of giving satisfactory service at temperatures of -40°C to +140°C with intermittent operation at temperatures up to 162°C maximum.

Construction B. This hose consists of a smooth bore tube of chlorinated polyethylene (CM) or ethylene acrylate (AEM) compound, resistant to Dexron VI (9986153) and/or engine oil (GME L0004, 93165209), dependent on the Category of the hose, which is reinforced with aramid braid, and has a cover of CM or AEM compound. The hose and/or hose assembly is capable of giving satisfactory service at temperatures of -40°C to +150°C with intermittent operation at temperatures up to 162°C maximum.

Construction C. This hose consists of a smooth bore tube of polyacrylate (ACM) compound or ethylene acrylate (AEM) compound, resistant to Dexron VI, reinforced with aramid braid, and a cover of ACM or AEM. The hose and/or hose assembly is capable of giving satisfactory service to temperatures of -40°C to +160°C with intermittent operation at temperatures up to 175°C maximum.

Categories. The "Category" of hose defines the fluid with which it has been qualified for service. The descriptions of the fluids used with this hose are as follows:

Category 1A. Automatic Transmission Fluid (ATF). Test with 9986153 (Dexron VI transmission fluid), Qualification with 9986153 Test Fluid qualifies the hose for use with AF40-AW1 (9274975) and Dexron III.

Category 1B. Automatic Transmission Fluid per blueprint requirements. Qualification tests are per blueprint requirements for the specific transmission oil part number.

Category 2A. Engine Oil. Test with GME L0004. Qualification with GME L0004 Test fluid qualifies the hose for use with other released GM engine oils.

Category 2B. Engine Oil per blueprint requirements. Qualification tests are per blueprint requirements for the specific engine oil part number.

Symbols. Not applicable.

Typical Applications. This specification covers hoses for use with either automatic transmission fluid or engine oil.

Remarks. Not applicable.
