The water inlet housing connects the radiator hoses to the thermostat. For certain applications, the water inlet contains threaded holes or ports for sensors and switches. These original equipment engine coolant thermostat/water inlet assemblies have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. Review: Great price and OEM Quality - OEM Thermostat for my 2004 Colorado. My truck used to run about a little over the 1/4 mark on the temp gauge but with this thermostat it is now closer to the half way mark which is indicative of the update they did to these to bring them up to 195 degree instead of 180. I was getting a P0128 code so my original thermostat was stuck open. To replace this, loosen your lug nuts on the drivers side wheel, jack the truck up on the drivers side, place a jack stand underneath the frame rail for safety, remove the wheel and the wheel splash shield held on by 6 plastic clips. Place a bucket or a catch pan underneath the truck and remove the lower radiator hose at the radiator. This will allow you to get rid of the old coolant that can accumulate sludge. Then also run a gallon of distilled water through the radiator and let it drain out. Also remove overflow bottle and drain that and clean it. I used two 9 inch long 1/4 extensions along with a swivel 10mm 6 point socket to remove the bolts. Once bolts are out pull the old thermostat housing away and the hose off the truck, so you can then have access to remove the stubborn clamp better.. Make sure you remove the old o-ring if it stays on the engine block. Wipe clean the mating surface. Put it all back together and fill with almost 2 gallons of Dex-Cool which you can also get on desertcart for a great price. I got rid of the stubborn clamp and used 2 regular worm type clamps I purchased at Vatozone. Easier to deal with than the OEM clamp.Tightening them from underneath the truck with my long extensions. Truck now runs about 2 tick marks shy of half way. Review: Fixed my issue - Fixed my issue of to cold coolant temp. I had a check engine light for coolant temp being too cold. My old thermostat was stuck open tank goodness instead of shut bc I could still drive it while the part came. It was the perfect fit and it has been in my truck for at least three years, so I'm gonna say the quality it very good. It returned the Heat level back into operating range!! ## Features - Repairs leaking thermostat housings - Corrects engine overheating caused by failed 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004942LSM | | Additional Features | Genuine, OEM part with nationwide warranty at any licensed dealership | | Backlight | No | | Best Sellers Rank | #570,003 in Automotive ( See Top 100 in Automotive ) #835 in Automotive Replacement Engine Thermostat Housings #1,130 in Automotive Replacement Engine Thermostats #15,777 in Automotive Replacement Engines & Engine Parts | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Color | Multicolor | | Connectivity Protocol | Wi-Fi | | Connectivity Technology | Wired | | Control Method | Touch | | Control Type | Button Control | | Controller Type | Manual | | Customer Reviews | 4.7 out of 5 stars 977 Reviews | | Display Type | analog | | Global Trade Identification Number | 00707773658994 | | Included Components | Coolant Thermostat | | Item Type Name | Coolant Thermostat | | Item Weight | 0.73 Pounds | | Manufacturer | ACDelco | | Manufacturer Part Number | 15-11073 | | Manufacturer Warranty Description | 24 month / unlimited mile limited warranty on parts sold on or after 04/01/18.

The gas releases heat, condensing into a high-pressure liquid. After cooling, the liquid passes over evaporator coils to cool the air as it is blown through the vents. **Q: What are the signs the system needs service?** A: Common indicators of an air conditioning system in need of service include warm and/or weak airflow through the vents, frequent on/off cycling of the system and a strange or musty odor. **Q: Is the puddle of water under my car a sign of AC problems?** A: Not necessarily. Condensation typically builds up on the AC evaporator and the water is drained at the bottom of the vehicle. That’s normal, but a larger puddle combined with reduced AC performance could indicate a problem. **Q: Does low refrigerant mean there’s a leak in the system?** A: In most cases the answer is yes. AC systems in older cars will experience refrigerant leakage over time, but a later-model vehicle that needs continual refrigerant recharging typically indicates a leak. **Q: Can a new cabin air filter improve AC performance?** A: Yes. A very dirty or clogged cabin air filter can reduce the airflow of the AC system, reducing its cooling efficiency and making the system work harder than normal. Periodic cabin filter replacements help the AC system keep its cool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price and OEM Quality *by J***Z on February 20, 2017* OEM Thermostat for my 2004 Colorado.
