The stock coolant reservoirs on these trucks are known to become cloudy and yellow with age becoming an eyesore when you're cleaning up the rest of your engine bay. More importantly, the stock units are notorious for the non-replaceable sensors that tend to fail prematurely causing a false low coolant warning. To fix the light on your dash using stock parts, you'll need to purchase and install a whole new coolant reservoir assembly...every time the sensor has an issue. To help clean up the under hood appearance of your truck and address this known failure point, our custom fabricated aluminum tanks include a high quality, cost effective float-type sensor that is easily serviceable for the life of your vehicle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDress up your engine bay by replacing the ugly clear or yellowed plastic coolant reservoir with our custom powder coated fabricated aluminum coolant tank with sight glass\u003c\/li\u003e\n\u003cli\u003eIncludes black anodized CNC machined billet aluminum cap, mounting hardware, overflow hose and easily replaceable low coolant sensor\u003c\/li\u003e\n\u003cli\u003eWill fit on stock trucks with no other modifications necessary\u003c\/li\u003e\n\u003cli\u003eUses OEM mounting points\u003c\/li\u003e\n\u003cli\u003eInstalls easily with basic hand tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eReplaces the following GM Part Numbers: \u003cspan class=\"item-part-number\"\u003e\u003cspan class=\"body-3 stock-code-text\"\u003e84257137, 84214124, 84138913, 84257137, 84174037\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e*Supersedes WCF100661\u003c\/p\u003e","brand":"Wehrli Custom Fabrication","offers":[{"title":"Default Title","offer_id":50199729176864,"sku":"WCF100433","price":494.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/wcfab-wcf100433-l5p-2019-l5d-duramax-oem-placement-coolant-tank-kit-4419194.jpg?v=1779548049"},{"product_id":"2017-2026-duramax-l5p-failed-coolant-bottle-sensor-fooler","title":"2001-2010 \u0026 2017-2023 Duramax L5P Failed Coolant Bottle Sensor Fooler","description":"\u003cp data-start=\"108\" data-end=\"169\"\u003e\u003cstrong data-start=\"108\" data-end=\"169\"\u003e2001-2010 \u0026amp; 2017–2023 Duramax L5P Failed Coolant Bottle Sensor Fooler\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"171\" data-end=\"438\"\u003eKeep your Duramax running strong without unnecessary warnings.
