In sub-freezing temperatures, cold cylinder liners sap compression heat, causing extreme cranking resistance, heavy white smoke emissions, wet stacking, and severe unburned fuel washdown past the piston rings. Without supplemental heating, low ambient cold starts accelerate cylinder liner glazing and place punishing shear loads on cold, high-viscosity crankcase oil, prematurely wearing connecting rod and main bearings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 1000W, 120V AC direct-immersion plate heater installs directly into the wet side of the engine block by replacing the factory side water jacket access plate. Utilizing a high-density, copper-sheathed electric heating element submerged directly in the jacket coolant, it induces thermal thermosiphon circulation without an auxiliary pump. The precision-stamped steel plate with heavy-duty elastomeric sealing prevents coolant leaks under cooling system operating pressures up to 15 PSI. Designed specifically for non-water-cooled compressor configurations, it provides an unobstructed flow path across the cylinder liners to ensure dependable starts down to sub-zero temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eDetroit Diesel 6-71 (Without Water-Cooled Compressor)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eInline-6 Two-Stroke (6-71)\u003c\/strong\u003e \/ \u003cstrong\u003eCommercial \u0026amp; Industrial\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e238 hp \/ 600 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A (Replaces Water Jacket Plate)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDetroit Diesel 6-71 Inline 2-Stroke Diesel Engines (Naturally Aspirated)\u003c\/li\u003e\n  \u003cli\u003eDetroit Diesel 6-71T Inline 2-Stroke Diesel Engines (Turbocharged)\u003c\/li\u003e\n  \u003cli\u003eFits applications WITHOUT water-cooled air compressors only\u003c\/li\u003e\n  \u003cli\u003eFits commercial truck, bus, marine auxiliary, and industrial gen-set configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Commercial \u0026amp; Industrial 6-71?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the Detroit Diesel 6-71 equipped with the \u003cstrong\u003eInline-6 Two-Stroke (6-71)\u003c\/strong\u003e engine lacking a water-cooled compressor.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to drain the cooling system before installation?\u003c\/h4\u003e\n\u003cp\u003eYes, completely drain the engine block coolant before removing the water jacket access plate to prevent flooding, and properly burp air pockets upon refilling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Detroit Diesel Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand the severe vibrations and extended run hours demanded by industrial machinery and commercial haulers, this immersion heating unit ensures maximum uptime and eliminates cold-weather engine wear.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67539517145336,"sku":"DS-EFTX1A8YW","price":143.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/engine-block-heater-for-detroit-diesel-6-71-without-water-cooled-compressor-1000w-1.jpg?v=1790650431","url":"https:\/\/performancechiptuning.com\/fr\/products\/engine-block-heater-for-detroit-diesel-6-71-without-water-cooled-compressor-1000w","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
