TheChevrolet Cobalt is a compact car introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt replaced both the Cavalier and the Toyota-based Geo/Chevrolet Prizm as Chevrolet's compact car. The Cobalt was available as both a coupe and sedan, as well as a sport compact version dubbed the Cobalt SS. Like the Chevrolet HHR and the Saturn ION, it was based on the GM Delta platform.

As with their predecessors, all Cobalts and its Pontiac equivalents were manufactured at GM's plant in Ramos Arizpe, Mexico and Lordstown, Ohio. The United States Environmental Protection Agency classified the Cobalt as a subcompact car.[1]

According to the Insurance Institute for Highway Safety (IIHS) the Cobalt receives an overall top score of "Good" for front collisions.[6]However, it receives a "Poor" overall score for side impacts without side curtain airbags,[7] and an "Acceptable" overall score with side curtain airbags.[8] In 2008, side curtain airbags became standard, but the Cobalt's structure remains the same and consequently in structure/safety category of the IIHS's side impact test the Cobalt receives a "Marginal" score. Side airbags are limited to the curtain type; torso type side airbags are unavailable.[9] According to the IIHS's injury measurements taken from the side impact test, the driver's torso is given a "Marginal" score.

On March 2, 2010, GM announced a recall of 1.3 million compact cars in North America, including the Chevrolet Cobalt, because of power steering problems.[13] GM implemented the repair on older models before fixing more recent models, as the car was replaced by the Chevrolet Cruze in late 2010. The Pontiac G5 and its international variants were also affected, though GM had already ended production of the Pontiac brand by that point.

On September 28, 2012, GM announced a recall of 40,859 cars including the Chevrolet Cobalt from the 2007-09 model year because of a potential fuel leak. Although the recall was limited to five states, vehicles from other southern states were covered for repair when summer heat caused cracks in the fuel reservoir assembly. The fuel vapor leak could be detected during hot days by a gasoline smell in the vicinity of the car.[14]

Faulty ignition switches in the Cobalts, which cut power to the car while in motion, were eventually linked to many crashes resulting in fatalities, starting with a teenager in 2005 who drove her new Cobalt into a tree.[15] The switch continued to be used in the manufacture of the vehicles even after the problem was known to GM.[16] On February 21, 2014, GM recalled over 700,000 Cobalts for issues traceable to the defective ignition switches. In May 2014 the NHTSA fined the company $35 million for failing to recall cars with faulty ignition switches for a decade, despite knowing there was a problem with the switches. Thirteen deaths were linked to the faulty switches during the time the company failed to recall the cars.[17][18]

In Canada, a rebadged variant of the Cobalt called the Pontiac Pursuit was sold from 2005 to 2006 as a sedan only. In 2006, another version of the vehicle was released in Canada, now called the Pontiac G5 Pursuit, and it was now available as both a sedan and a coupe. In Mexico, the vehicle was called the Pontiac G4 and was sold as both a sedan and a coupe from 2005 to 2006.

In the United States, the Pontiac G5 went on sale in 2006 as a 2007 model, serving as the replacement for the Pontiac Sunfire, and was only available as a coupe. In Canada and Mexico, the Pontiac G5 went on sale in early 2007 as a 2007 model, available as both a sedan and coupe.

General Motors discontinued the Pontiac G5 in the United States in 2009, and it was discontinued in Canada and Mexico in 2010. The Chevrolet Cruze served as a replacement for both the Chevrolet Cobalt and Pontiac G5.

In 2009, Chevrolet launched the Cobalt's eventual successor, the Chevrolet Cruze (based on the new Delta II platform), in Europe, with launches in other markets (including the US) following in 2010. The Cobalt ended production on June 23, 2010.[21][22] With the discontinuation of the Pontiac brand by GM in 2010, the Buick Verano is marketed as the G5's successor in Canada, while the Cruze serves as a de facto replacement for the Pontiac G5 in the United States.

In 2011, General Motors Brazil introduced a new model bearing the Cobalt name in the Brazilian market.[26] This Cobalt replaced the aging local Chevrolet Astra. The car is equipped with a 1.4 Econo.Flex engine. Although sporting a similar front end style, it is not directly related to the Chevrolet Agile, since it shares the overall underpinnings with the 2011 Chevrolet Sonic,[27] while the Agile is derived from the considerably older Opel Corsa B, from 1993.

Chevrolet had no plans to bring the Cobalt to the North American market, which already had the Chevrolet Sonic and Chevrolet Spark as the subcompact cars in the continent. In GM Brazil's line-up, it is situated above the Chevrolet Prisma and below the Chevrolet Cruze.

The Chevrolet Cobalt was assembled in Colombia too. It was equipped with a simple range of two versions and a single 1.8-liter 8-valve 106-horsepower engine. With a very discreet commercial performance and a taxi variant, its production in the Colombian market ended in early 2016.[29]

In Brazil, production ended in late 2019, with 2020 being the final model year. The Cobalt has been succeeded by the Chevrolet Onix Plus sedan, which achieved higher sales upon its launch in 2019.[32]

After UzAuto phased out the Ravon brand in 2020, the Ravon R4 was once again renamed the Chevrolet Cobalt.[33] The Cobalt / R4 made by UzAuto never received the 2015 facelift seen in other markets.[34]

I have a 2009 Chevy Cobalt bought used a year ago from a dealership near me. It has about 81,000 miles on it and just recently started messing up. My coolant temp will start heating up to about 200F-206F when idle. The normal running coolant temp I had logged before all this was 190F. Then, whenever I start moving from a standstill, my car will lose the ability to accelerate with ENG PWR REDUCES message on readout. I'll park and turn off engine wait a while and turn it back on and I can drive again with coolant temps around 200F.

The Chevy Cobalt motor was introduced in 2005 by Chevrolet. The engine was based on the GM Delta platform. There are two generations of the Chevy Cobalt ranging from 2005-present, and you can find both new and used Chevy Cobalt engines for sale on eBay.

The second-generation Chevy Cobalt has been manufactured since 2011. However, the model is no longer available in the United States. In the U.S., the Cobalt nameplate was replaced by the Chevy Cruze sedan in 2011.

Currently, Brazil manufactures the Cobalt, and it is available in 40 countries across Europe, the Middle East, South America, and Africa. So, searching for a Cobalt engine from 2005-2010 will be easier than looking for a new Chevy Cobalt engine after 2011.

The Cobalt SS engine for sale is different from standard engines in the Cobalt model. The Super Sport (SS) is the signature performance Chevy. It was first made available with the Impala in 1961. The SS designation means it is powerful.

The SS model was discontinued in 2010. These are the two basic SS engines utilized by Chevy for the Cobalt. You can find 2007 Chevy Cobalt motor in a Super Sport, but a 2007 Chevrolet Cobalt engine 2.2-liter 4-cylinder is not a Super Sport.

***Some other sellers of computers do not disclose that these procedures must be done until you have bought the product---others claim that their units are 100% plug and play. To be 100% plug and play they would have to alter the function of the computers original design and you might lose your antitheft protection and the ability to detect engine misfires. The proper way to replace an engine computer and be sure your vehicle remains in it's original condition is to do both the antitheft relearn and crankshaft variation relearn if applicable.***

I'm not building a kit car. I'm just moving the Drive line and sub frame from the front to the rear of the car. It will have an "empty" sub frame up front(no drive train up front). You can see in the pic, the sub frame is mounted in the rear and rear floor is cut away. Will be slow progress as I will not be in the shop again until April 1.

Certainly a curiosity, I am not expecting to get this unit classified by any group other than my state allowing me to use it as an automobile. The SCCA is way down the road from this effort. It's got to be a car before it can be a Race car. IMO. I do not expect, initially, change the power train and emissions controls in any way. From running as a road going automobile the future is wide open.

The Cobalt package attracted me for many reasons not the least was it's electrically assisted P/S is in the dash, so no hydraulic lines and/or pump. The engine package and trans is narrower than the rear seat cushion thus the uni-body frame in the rear is wider than the engine/trans package.(I'm a cheater, I took out the back seat cushion and laid it across the engine compartment.)

Pleased to have you along! A running, completed car has many roads to choose from. Brandonsmash wondered how SCCA would class it? I don't know, but when it drives I'm going to find out! I think if they put it in with other old sidewiders(FWD) those will lose badly. I don't worry about all that because I just want to drive it down the road!

I now see what you are saying! I guess I know this car so well I know this picture is looking IN the passenger door! The sunshine is behind the car out the garage door. See the remains of the spare tire area? This shot is like looking through the invisible back seat. The pass seat is not in the car either adding to confusion.
