It takes the place of the factory rear engine coolant cover, GM P\/N 97941204. This is a 6.6L part only; the 3.0L and 2.8L Duramax are not covered. Verify fitment by VIN or call us before you order.

OE covers are prone to leakage as the gaskets dry out, and the factory cast covers corrode. Their billet coolant block off plate with an integral O-ring is an upgrade for your rear engine cover, and Fleece says it will stop the coolant leaks for good.\u003c\/p\u003e\n\u003cp\u003eBefore you blame the rear cover for low coolant, rule out the other leak points these trucks are known for. On the LB7, the early water pump seal design was a documented failure, as early as 75,000 miles. On the LMM, water pumps seep at the weep hole and leave crusty residue as they age and heat-cycle. On the L5P, the plastic upper radiator hose fittings and the edges of the coolant reservoir can crack after long heat exposure, which leaves orange DEX-COOL residue and a sweet smell. If the system is hard and pressurized after shutdown, or the overflow tank bubbles, look at the head gasket instead. A wet, crusted rear cover is the leak this plate fixes.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBillet coolant block off plate, Fleece part number FPE-DMAX-CBOP\u003c\/li\u003e\n\u003cli\u003eIntegral O-ring seal built into the plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Fleece Performance Engineering\u003c\/h2\u003e\n\u003cp\u003eBrothers Brayden and Chase Fleece started Fleece Performance Engineering in 2008, and the company is headquartered in Pittsboro, Indiana.

The larger head bolts used from 2019 were meant to address it, so it's a lower-probability item on 2019 and newer engines.

A malfunctioning switch can fail to indicate when your engine is low on coolant, which leaves you with overheating issues and problems that can seriously damage the engine. It is a commonly replaced part once a truck hits around 100,000 miles.\u003c\/p\u003e\n\u003cp\u003eThat warning matters on these engines because they have known ways of losing coolant. On the LB7, the early water pump seal design was deficient and could need replacement as early as 75,000 miles, with low coolant warnings and overheating as the result. On the LBZ, the original water pump's impeller and seals wear with heat cycles, typically between 80,000 and 120,000 miles, and low-coolant warnings are one of the signs. LMM water pumps can seep at the weep hole as they age, which shows up as intermittent low coolant. On the LB7 and LMM, a head gasket failure can pressurize the cooling system and push coolant out. A working float switch is how you catch those before the engine pays for it. Merchant Automotive designed the 10061 so your coolant level is accurately monitored at all times.\u003c\/p\u003e\n\u003cp\u003eIt also makes sense as added insurance when you are already doing a coolant job, to protect your engine for years to come.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCoolant tank float switch assembly, Merchant Automotive part number 10061\u003c\/li\u003e\n\u003cli\u003eFactory-like wiring\u003c\/li\u003e\n\u003cli\u003eFactory-correct plug for a quick and easy replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFeatures, as Merchant Automotive lists them:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEasy Installation\u003c\/li\u003e\n\u003cli\u003ePlug \u0026amp; Play Design\u003c\/li\u003e\n\u003cli\u003eDirect Replacement\u003c\/li\u003e\n\u003cli\u003eFactory Style Wiring\u003c\/li\u003e\n\u003cli\u003eCan Clear A Coolant Light On Dashboard\u003c\/li\u003e\n\u003cli\u003eEnsures You Have The Right Amount Of Coolant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Merchant Automotive\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/merchant-automotive\"\u003eMerchant Automotive\u003c\/a\u003e was founded in 2004 and is based in Holland, Michigan.

At 180 degrees, it opens, allowing coolant to flow to the radiator.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch5\u003eFeatures:\u003c\/h5\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes New Seals\u003c\/li\u003e\n\u003cli\u003eDirect-Fit Replacement\u003c\/li\u003e\n\u003cli\u003eFront \u0026amp; Rear Thermostat Included\u003c\/li\u003e\n\u003cli\u003eOEM Temperature Thermostats (185 \u0026amp; 180)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eKit Includes:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003eOil Fill Tube Seal\u003c\/div\u003e\n\u003cdiv\u003eRear Thermostat\u003c\/div\u003e\n\u003cdiv\u003eFront Thermostat\u003c\/div\u003e\n\u003cdiv\u003eUpper Radiator Pipe Seal\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\u003cspan\u003e\u003cstrong\u003e\u003cu\u003e\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\n\u003ca href=\"https:\/\/www.xtremediesel.com\/xtreme-diesel-performance-xdp-product-warranty-availability#warranty\"\u003e\u003cspan\u003e\u003cstrong\u003e\u003cu\u003eManufacturer Warranty*:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e1 Year\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"Merchant Automotive","offers":[{"title":"Default Title","offer_id":51230057070880,"sku":"10428","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/merchant-automotive-10428-engine-coolant-thermostat-kit-2001-2010-duramax-8517710.jpg?v=1779542948"},{"product_id":"merchant-automotive-10307-rear-cover-coolant-seals-pair-2001-2010-duramax","title":"Merchant Automotive 10307 Rear Cover Coolant Seals (Pair) (2001-2010 6.6L Duramax)","description":"\u003csection class=\"cmp-product-section cmp-product-section--toggle cmp-product-section--toggle-open animate--fade-in\" data-scroll=\"\"\u003e\n\u003cdiv class=\"cmp-product-details-wrapper\"\u003e\n\u003cdiv class=\"cmp-product-description\"\u003e\n\u003cdiv class=\"cmp-product-section__inner\"\u003e\n\u003cdiv class=\"cmp-product-description__content\"\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\n\u003cdiv\u003ePick up the Merchant Automotive 10307 Rear Cover Coolant Seals (Pair) from SDS for your GM 6.6L Duramax today.

When it glitches, the truck can throw a code and trigger warnings even when the coolant level is fine. The fooler mimics the factory sensor's resistance range, so the ECM keeps reading a healthy level and you stay focused on the road or the job instead of a warning light.\u003c\/p\u003e\n\u003cp\u003eOne caution from the shop floor: a fooler only covers a bad sensor. It cannot tell you when coolant is actually low, so rule out a real leak first. On the L5P, the plastic upper radiator hose fittings and the edges of the coolant reservoir can develop hairline cracks after long heat exposure, which shows up as orange DEX-COOL residue, a sweet smell and genuine low-coolant warnings. Water pump leaks are also reported across L5P years, sometimes as a weep from the pump and a temperature gauge that climbs under load. Check the level cold, look for residue around the tank and pump, and only then blame the sensor.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e1x Coolant Bottle Sensor Fooler\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eKey features from the maker:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect plug-and-play design\u003c\/strong\u003e — installs easily in place of the factory reservoir sensor with no cutting, splicing, or redesigning wiring harnesses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable signal emulation\u003c\/strong\u003e — mimics the factory sensor’s resistance range so the ECM reads a healthy coolant level even when the original sensor fails.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrevents nuisance CELs\u003c\/strong\u003e — stops annoying dashboard alerts and limp-down conditions tied to the coolant bottle sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for LB7, LLY, LBZ, LMM and L5P Trucks\u003c\/strong\u003e — specifically calibrated for the 2017–2026 Duramax (L5P) engine platform that is known to have the most issues with this problem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable and dependable\u003c\/strong\u003e — built to withstand under-hood heat, vibration, and exposure common in diesel work environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation notes\u003c\/h2\u003e\n\u003cp\u003eQuick install tip: no special tools required.
