Or you're sitting in winter traffic and that gauge won't budge off cold no matter how long you're idling. Something's wrong. The thermostat's stuck. It's not opening when it should or it's not closing right. This is genuine Honda OEM part 19301-RAF-004. It's the standard thermostat for K-series engines. It opens at about 87°C (183°F) and that's exactly what your engine needs. When it's working right you don't even think about it. The temperature stays perfect. When it fails you're either overheating or running cold. Replace it when you're getting temperature problems. Don't ignore a stuck thermostat because you're looking at real engine damage.\u003c\/p\u003e\n\n\u003ch4\u003eHere's What Your Thermostat's Actually Supposed To Do\u003c\/h4\u003e\n\n\u003cp\u003eYou've got the thermostat sitting between your engine and the radiator. When you first crank the engine it's freezing cold so the thermostat's closed. The coolant's not going through the radiator yet. It's just cycling through the engine block so the engine warms up fast. You're not wasting heat dumping cold coolant through the radiator when the engine needs to get warm. Once your engine hits about 87°C (183°F) that's when the thermostat opens. Now coolant's flowing through the radiator and cooling things down. All day long it's opening and closing. It's constantly tweaking to keep your engine right at the perfect temperature. When it's working you don't know it's there. The gauge sits where it belongs. The heater works. Everything's normal. When the thermostat fails that all goes away.\u003c\/p\u003e\n\n\u003ch4\u003eStuck Open And Your Engine Won't Get Warm\u003c\/h4\u003e\n\n\u003cp\u003eIf your thermostat's stuck open the coolant's running through the radiator constantly. Your engine can't get to operating temperature. The gauge's staying low. You're sitting in winter and the heater's blowing cold. You're waiting and waiting for hot air and it never comes. The engine's never actually warming up. The ECU thinks you're still warming up so it's dumping extra fuel in there. You're getting terrible gas mileage for no reason. The engine feels weak and sluggish. All of that's because the thermostat opened and it's never closing. It's not going to destroy your engine but it's annoying and it's costing you money every time you drive. Replace it and be done with it.\u003c\/p\u003e\n\n\u003ch4\u003eStuck Closed And You're Overheating - Pull Over Now\u003c\/h4\u003e\n\n\u003cp\u003eIf your thermostat's stuck closed the coolant can't get through the radiator at all. Your engine's heating up with nowhere to cool down. It's just getting hotter and hotter. The temperature gauge's climbing into the red. Warning lights are coming on. The engine's dangerously hot. We've seen people ignore overheating because they're stubborn or they're not paying attention. They keep driving thinking it'll fix itself. It doesn't. The cylinder head warps from heat. The head gasket fails and you're losing coolant internally. The block can actually crack if it gets hot enough. Pistons seize. Valves bend. The whole engine's done. All because a thermostat was stuck and nobody replaced it. Don't do that. If that temperature gauge is climbing into the hot zone you're pulling over right now. Let it cool. Check your coolant. If you've got coolant and it's still hot the thermostat's stuck. Replace it immediately.\u003c\/p\u003e\n\n\u003ch4\u003eStandard 87°C Thermostat - Get The Real Honda Part\u003c\/h4\u003e\n\n\u003cp\u003eThis is the standard thermostat that opens at about 87°C (183°F). That's the exact temperature Honda engineered for K-series engines. It's not some race thermostat somebody's pushing. It's not some cheapo economy version. It's what Honda installs at the factory on K20Z3, K24A2, K24Z6, and K24Z7 engines. The thermistor inside responds exactly the way Honda designed it. The opening temp's right. The closing temp's right. When you install this your cooling system's going to regulate exactly how it's supposed to. Aftermarket thermostats are cheaper. Some are fine. Some don't open at the right temperature. We've seen cheap thermostats that open too early. Your engine runs cold all the time. The heater barely works. We've seen ones that open too late so you're overheating before they finally open. We've seen cheap ones that completely jam up within a year because the parts inside are garbage. Temperature control's not where you gamble. Buy the Honda thermostat. It opens right. It closes right. It doesn't stick. You install it and you're moving on.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHonda OEM standard thermostat - part number 19301-RAF-004\u003c\/li\u003e\n  \u003cli\u003eFits K20Z3, K24A2, K24Z6, K24Z7 engines\u003c\/li\u003e\n  \u003cli\u003eGenuine Honda thermostat - not aftermarket\u003c\/li\u003e\n  \u003cli\u003eOpens at ~87°C (183°F) - factory-spec temperature\u003c\/li\u003e\n  \u003cli\u003eDirect replacement\u003c\/li\u003e\n  \u003cli\u003eOne thermostat per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003e2013-2015 Acura ILX (K20Z3 engine)\u003c\/li\u003e\n  \u003cli\u003e2004-2008 Acura TSX (K24A2 engine)\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Honda Civic Si (K20Z3 engine)\u003c\/li\u003e\n  \u003cli\u003e2007-2014 Honda CR-V (K24Z6 and K24Z7 engines)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Standard thermostat for K20Z3, K24A2, K24Z6, K24Z7 engines. Genuine Honda OEM part 19301-RAF-004. Opens at ~87°C (183°F) factory-spec temperature. Maintains proper engine operating temperature. Failed thermostat causes stuck open (engine won't warm up, poor heater, terrible fuel economy) or stuck closed (overheating, warning lights, cylinder head warp, head gasket failure, cracked block, seized pistons). Replace when temperature gauge incorrect, overheating occurs, or during cooling system service. Don't ignore overheating - risk of engine destruction. Standard temperature opening only - verify part number before ordering. Direct factory replacement. One thermostat per order.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n 2013-2015 Acura ILX\u003cdiv\u003e2004-2008 Acura TSX\u003c\/div\u003e\n\u003cdiv\u003e2006-2015 Honda Civic Si\u003c\/div\u003e\n\u003cdiv\u003e2007-2014 Honda CR-V\u003c\/div\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Thermostat\u003cdiv\u003e(1) Thermostat Housing\u003c\/div\u003e\n\u003cdiv\u003e(1) Thermostat Gasket\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Honda","offers":[{"title":"Default Title","offer_id":45642703142946,"sku":"OHA-19301-RAF-004","price":126.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/OHA-19301-RAF-004_dd03.jpg?v=1780076778","url":"https:\/\/www.hybrid-racing.com\/products\/honda-k20z3-k24a2-k24z7-standard-thermostat-19301-raf-004","provider":"Hybrid Racing","version":"1.0","type":"link"}
