This original equipment engine coolant thermostat kit has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. Review: Awsome price - Works, functioned, and fit like o.e. because that's what it is. Review: Matched original 2002 duramax - Identical replacement to the one that came out of my 2002 Chevy 2500HD Duramax. My original thermostat got stuck open, so it would take 30+ minutes for engine temp to get up over 165 degf, which is too cold for this engine to run. Once swapped out with this one ( and also swapped out the other thermostat - there are two thermostats side by side under the same housing in this engine, one opens at 182 and the other 185 degf), engine got up to temperature like it should in 10 minutes or so. Changing this was fairly easy. I drained the coolant by removing lower radiator hose (there is a drain Petcock on the bottom of the radiator, bit after breaking a few of these on other vehicles, I always just pull the lower radiator hose). Pulled intake resonance chamber, alternator positive cable, and unplugged a few wiring connections. After that, was able to pull thermostat housing, scrape clean with razor blade, and out back together. You don't need any gasket on the thermostat housing - rubber thermostat gasket supplied with parts is all you need. Refill coolant 50/50 dexron and distilled water then bled air out of engine block (there is an air bleed bolt on top of the thermostat housing you can use to do this). After air bled, started engine, let warm up until thermostats opened ( can feel upper radiator hose get warm). Once thermostats open, it will suck down about held the coolant reservoir, so make sure it's full. All in all, easy job. Took about 4 hrs. Fixed the issue. ## Features - comes with the thermostat and gasket you need to replace the thermostat - gm-recommended replacement part for your gm vehicle’s original factory component - offering the quality, reliability, and durability of gm oe - manufactured to gm oe specification for fit, form, and function - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C9829A | | Additional Features | Genuine, OEM part with nationwide warranty at any licensed dealership | | Backlight | No | | Best Sellers Rank | #39,951 in Automotive ( See Top 100 in Automotive ) #40 in Automotive Replacement Engine Thermostats | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Color | Silver | | Connectivity Protocol | Wi-Fi | | Connectivity Technology | Wi-Fi | | Control Method | Touch | | Control Type | Button Control | | Controller Type | OEM | | Customer Reviews | 4.7 out of 5 stars 578 Reviews | | Display Type | analog | | Global Trade Identification Number | 00021625400228 | | Included Components | ACDelco - Engine Coolant (Slp) (131-131) | | Item Dimensions D x W x H | 2.99"D x 2.01"W x 2.99"H | | Item Type Name | ACDelco - Engine Coolant (Slp) (131-131) | | Item Weight | 0.2 Pounds | | Manufacturer | ACDelco | | Manufacturer Part Number | 131-131 | | Manufacturer Warranty Description | 24 month / unlimited mile limited warranty on parts sold on or after 04/01/18.
