It regulates the small amount of air that bypasses the throttle plate to maintain a stable idle speed as engine load and temperature change, a function that is critical on EFI-equipped inboard and sterndrive engines where idle quality directly affects starting, warm-up, and low-speed maneuvering. Sierra engineers this part to meet or exceed the specifications of the original equipment component it replaces, and Sierra supplies parts to OEM engine manufacturers and boat builders, so the 18-7632-1 is built to the same fit, form, and function expected on the water.\u003c\/p\u003e\u003cp\u003eThe motor measures 10.7 inches in length with a 1.2 inch outside diameter and a 0.6 inch nominal wall thickness, and it is finished in white. It is designed as a direct-fit replacement for the 5.7L EFI, 5.7L EFI GEN+, 5.7L EFI MIE GEN+, and 5.7LX Bravo EFI GEN+ engine families covered below, matching the mounting and electrical interface of the factory idle air control motor on these applications.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7632-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Idle Air Control Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 10.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter:\u003c\/strong\u003e 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Wall Thickness:\u003c\/strong\u003e 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282374457\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Displacement:\u003c\/strong\u003e 5.7L 350 cubic inch V-8\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5.7L EFI, 1995-1997, serial range F225560 - K999999\u003c\/li\u003e\n\u003cli\u003e5.7L EFI (GEN +), 1998-2001, serial range L010035 - M299999\u003c\/li\u003e\n\u003cli\u003e5.7L EFI MIE (GEN +), 1997, serial range K040300 - K999999\u003c\/li\u003e\n\u003cli\u003e5.7LX Bravo EFI (GEN +), 1996-1997, serial range F800300 - K999999\u003c\/li\u003e\n\u003cli\u003e5.7LX EFI, 1995-1997, serial range F225560 - K999999\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7632-1 idle air control motor fit?\u003c\/strong\u003e The 18-7632-1 fits 5.7L 350 cubic inch V-8 EFI engines, specifically the 5.7L EFI (1995-1997, serial F225560 - K999999), 5.7L EFI GEN+ (1998-2001, serial L010035 - M299999), 5.7L EFI MIE GEN+ (1997, serial K040300 - K999999), 5.7LX Bravo EFI GEN+ (1996-1997, serial F800300 - K999999), and 5.7LX EFI (1995-1997, serial F225560 - K999999).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if this part fits my engine by serial number?\u003c\/strong\u003e Check your engine's serial number against the ranges listed for the 18-7632-1: F225560 - K999999 for the 1995-1997 5.7L EFI and 5.7LX EFI, L010035 - M299999 for the 1998-2001 5.7L EFI GEN+, K040300 - K999999 for the 1997 5.7L EFI MIE GEN+, and F800300 - K999999 for the 1996-1997 5.7LX Bravo EFI GEN+.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does an idle air control motor do?\u003c\/strong\u003e It regulates the amount of air bypassing the throttle plate to keep engine idle speed stable as load and temperature change.
