In spite of its appellation, you could purchase the 2007 Cobalt in expanded colours than even-handed clouded moody.
In the 2005 design year, Chevrolet began phasing absent the aging Cavalier and introduced its eventual replacement, the Cobalt. Unfortunately, it was nowhere near as fruitful as its predecessor, and Chevy discontinued it after decent six base oldness. The 2007 Cobalt came average with a 2.2-liter engine that used GM's proprietary Dex-Cool coolant to grasp it within an fine temperature scale. Chevy recommended flushing and refilling the 2.2-liter engine's cooling step every 60 months or 150,000 miles, whichever came ahead. Flushing the 2007 Cobalt's coolant is another epoch consuming than backbreaking, on the other hand the chicamin you save makes it hale price your date.
1. Unscrew the cap from the coolant degas bottle slowly. Whether you hear a hissing sound, objective loosening the cap until the hissing sound stops. Once you remove the cap, fix it in a secure aim to prevent losing or bad it.
2. Commencement the engine and acquiesce it to lazy until the upper radiator hose is febrile to the touch. Shut the engine off.
3. Lift the front of the Cobalt with a floor jack and slide jack stands under its subframe. Lower the vehicle onto the subframe.
4. Slide under the passenger's side of the vehicle and good buy the petcock, the radiator withdraw plug, on the backside of the radiator. Position a withdraw pan directly under the petcock. Wrap your handwriting in a thick shop cloth to protect it from heat and turn the petcock counterclockwise to begin the flow of coolant into the extract pan.
5. Brisk the petcock once the flow of coolant stops. Lift the vehicle off the jack stands with a floor jack and remove the jack stands. Lower the vehicle to the ground.
6. Hint the lower radiator Issue hose, the hose on the Chauffeur's side of the radiator, until you extent the thermostat housing. Catch where the thermostat housing connects to the bathe pump inlet tube meeting and hint that toward the engine. Good below where the damp pump inlet tube meeting connects to the engine block is the damp pump filter plug.
7.15. Start the Cobalt's engine and hold the engine speed at 2,000 to 2,500 rpm for three minutes. Allow the engine to idle for 30 seconds, then shut the engine off.16.
Hand-tighten the water pump drain plug, then torque it to 16 inch-pounds, using an inch-pound torque wrench and socket, once the coolant stops draining from the engine block.
9. Pour clean water into the degas bottle until the level reaches the "Cold Fill" line. Do not install the cap onto the degas bottle.
10. Transfer the drained coolant from the drain pan to a clean 5-gallon bucket.
11. Start the engine and hold the rpm at 3,000 for three minutes after the upper radiator hose is warm to the touch to allow the water to circulate through the system.
12. Wait until the engine is cool to the touch, then repeat Steps 3 through 11 until only clean, colorless water comes from the radiator and engine block when you drain them.
13. Pour 50-50 premixed Dex-Cool coolant into the degas bottle until the level remains steady at the "Cold Fill" line. The cooling system holds a total of 1.7 to 1.85 gallons, on the 2.2-liter and 2.4-liter engines, but the exact amount needed may vary.
14. Tighten the cap onto the coolant degas bottle.
Position a extract pan under the hose pump bleed plug and loosen it with a ratchet and socket. Wrap your labourer in a thick shop cloth and remove the plug by help to filter the engine block.8.
Allow the vehicle to sit until its engine is cool to the touch and check the coolant level in the degas bottle. If needed, unscrew the cap from the degas bottle and add 50-50 premixed Dex-Cool coolant until its level reaches the "Cold Fill" line.
17.Take the coolant in the 5-gallon bucket to a local used automotive fluid recycler for disposal. Some auto parts stores take old coolant free of charge.
