DIY How To Change a Thermostat on a 2005 2006 2007 2008 Chevy Chevrolet Equinox Pontiac Torrent
Before you consider paying upwards of $150-300 follow these instructions and buy your own quality parts and you can insure it's done right and you aren't being overcharged. Very easy to do, literally takes a few minutes. Stop throwing money out the window and DIY. Thermostat tells the car how much antifreeze to flush to the engine to keep it cool. If it's not flowing expect it to run hot. Hot engines equal cracked engine, cracked engine is no good might as well part out the car! lol The primary function of a thermostat is to maintain a minimum operating temperature in your car's engine. When you start your engine cold, the antifreeze / coolant mixture is kept within the engine by the thermostat. When the coolant temperature reaches the specified opening point of the thermostat, it opens. Coolant will then flow through the radiator to keep the engine at a temperature close to the rated temperature of the thermostat. Most of today's cars and trucks are designed to operate with a 195* F thermostat. If a lower temperature thermostat has been installed, it will affect several systems in your car. A vehicle with a computer controlled carburetor or fuel injection will sense the lower temperature and compensate by making the engine run richer, causing excessive fuel consumption and possibly a high idle. A lower temperature thermostat will also decrease the amount of heat available to keep you warm and defrost your windshield. Then again, if your thermostat is stuck partially or completely open, you will have the same symptoms as an incorrect thermostat. Unfortunately, a thermostat that is stuck only slightly open will cause double trouble. It will make the engine take much longer to warm up, but may not allow enough coolant to flow at high speed to keep the engine cool and might cause an overheating condition. A thermostat can last many years but it might be a good idea to have it replaced the next time your cooling system is being serviced as a preventive maintenance procedure. Also, remember that most manufacturers recommend a cooling system reverse Flush and refill every two years.





How to Replace Thermostat and Housing in Chevy Silverado
http://chevroletforum.com/how-tos is the leading Chevy Silverado resource for technical guides. The thermostat is a simple device that detects coolant temperatures and opens or closes a passage to the radiator. For the full step-by-step article, please visit http://chevroletforum.com/how-tos/a/chevrolet-silverado-1999-2006-how-to-re place-thermostat-and-housing-392998 This passage remains open as long as the coolant is above the thermostat's rated temperature. Since thermostats wear over time and its internal seals begin to deteriorate, the result is poor engine cooling. If the thermostat in your Chevy Silverado stops working, watch the following steps for a comprehensive DIY replacement. Replacing the thermostat and housing in your Silverado will take two to three hours to complete. The difficulty is moderate since it requires working in areas with limited accessibility. Compared to what a pro shop or the dealer would charge you for this repair, forty to sixty dollars to do-it-yourself is a steal. The supplies you’ll need are: a new thermostat, a flat head screwdriver, 10 millimeter socket, a ratchet, a catch pan, pliers, pry bar, sand paper, and coolant. Step 1 – Drain the Coolant Remove the coolant overflow bottle cap. Go behind or under the driver side front wheel. Near the bottom corner of the radiator is a thumb screw that is the radiator drain. Remove that and let the fluid run into the catch pan. Step 2 – Remove Air Intake Duct Loosen up these hose clamps with a flathead screwdriver. Pull both ends of the intake hose out. To remove it, just lift it up and out. Step 3 – Disconnect Lower Radiator Hose Using pliers, push the two teeth together on this hose clamp. Next, slide the clamp up the hose. Using the pry bar, pry the hose free. Pull back on it with the pry bar and pull on the hose with your other hand at the same time to get it out. Step 4 – Remove the Thermostat Remove this 10 millimeter bolt and the matching bolt on the bottom of the thermostat. Pull out on the thermostat, making sure to have the catch pan underneath first. Then pull the thermostat out the rest of the way. Step 5 – Install New Thermostat and Housing Use the fine grit sandpaper to clean up any corrosion on the housing. Then clean up any debris left behind really well. Take the new thermostat and feed it down into place. Then replace the two 10 millimeter bolts. Tighten them to about 15 to 17 foot pounds. Push the hose back into place. Then slide the hose clamp back down. Take the intake hose and feed it back down into place. The hose needs to go underneath the radiator hose. Once they’re both into place, push this hose back up and in. It will clip onto the side. Tighten up these two clamps with the flathead screwdriver. Replace the coolant to the max fill line. Start the vehicle and let it warm. Then check where the coolant level is, and refill if necessary.
