It is a direct fit for the ignition system, restoring a proper seal against moisture and delivering reliable spark distribution to keep the engine firing correctly on every cylinder. The cap is finished in white with a twist-on closure for a secure, tool-free installation and removal during routine maintenance.\u003c\/p\u003e\u003cp\u003eThis distributor cap is a wear item that should be inspected and replaced when it shows cracking, carbon tracking, corrosion at the terminals, or a compromised twist-on seal, all of which can cause misfires, hard starting, or rough idle. Installing the correct Sierra 18-5243 cap for a Delco HVS V-6 distributor with extended bracket ensures the terminals and cap geometry line up properly with the rotor and ignition wiring, so the ignition system performs as designed.\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 18-5243\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Distributor Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosure Type:\u003c\/strong\u003e Twist-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 3.6 x 7.1 x 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282167547\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Engines equipped with Delco HVS distributor with extended bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 3859019\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eDelco HVS V-6 Distributors (engines equipped with Delco HVS distributor with extended bracket)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e3859019\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5243 distributor cap fit?\u003c\/strong\u003e The Sierra 18-5243 fits engines equipped with a Delco HVS distributor with an extended bracket, specifically Delco HVS V-6 distributors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5243 the same cap used on V-8 Delco HVS distributors?\u003c\/strong\u003e No, the 18-5243 is built for Delco HVS V-6 distributors; a V-8 Delco HVS distributor uses a separate cap part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM number does the Sierra 18-5243 replace?\u003c\/strong\u003e It replaces OEM number 3859019.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-5243 distributor cap?\u003c\/strong\u003e It is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Sierra 18-5243 secured to the distributor?\u003c\/strong\u003e It uses a twist-on closure, allowing it to be installed and removed without additional tools.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-5243?\u003c\/strong\u003e The cap measures 3.6 x 7.1 x 5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5243 distributor cap weigh?\u003c\/strong\u003e It weighs 0.68 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many caps come in a Sierra 18-5243 purchase?\u003c\/strong\u003e One distributor cap (unit count of 1) is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the Sierra 18-5243 distributor cap be replaced?\u003c\/strong\u003e Replace the 18-5243 when the cap shows cracking, carbon tracking, terminal corrosion, or a worn twist-on seal, since any of these can cause misfires or hard starting on a Delco HVS V-6 distributor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5243 a genuine aftermarket replacement or a used OEM part?\u003c\/strong\u003e The 18-5243 is a new aftermarket distributor cap manufactured by Sierra as a direct replacement for OEM number 3859019.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988202762459,"sku":"SIE-18-5243","price":74.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5243_lg__64189.1558127563.500.750.jpg?v=1785188376","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5243-distributor-cap-for-mercruiser-4-3l-v-6-alpha-bravo-sterndrive-replaces-oem-888731-898253t23","provider":"Good Vibes Marina","version":"1.0","type":"link"}
