What engine is in a 2007 Chevy Cobalt LT?

The 2007 Chevy Cobalt LT uses two Ecotec inline-four engines depending on the build: a standard 2.2-liter and an optional 2.4-liter.


In general, the 2.2-liter engine (Ecotec L61) delivers about 145 horsepower and around 150 lb-ft of torque. The 2.4-liter engine (Ecotec LA1) provides roughly 172 horsepower and about 165–170 lb-ft of torque. Both engines were paired with front-wheel drive, with transmission options typically including a five-speed manual or a four-speed automatic (4T45-E) in most LT configurations.


Engine options for the 2007 Cobalt LT


The LT trim of the 2007 Cobalt offered two main powertrain choices. Here are the key specifications you’re most likely to encounter:



  • 2.2-liter Ecotec inline-four (L61) — approximately 145 hp and 150 lb-ft of torque. Typically paired with a 5-speed manual or a 4-speed automatic (4T45-E).

  • 2.4-liter Ecotec inline-four (LA1) — approximately 172 hp and 165–170 lb-ft of torque. Transmission options commonly included a 5-speed manual or a 4-speed automatic (4T45-E).


Concluding note: The LT designation could correspond to either engine depending on the specific build date and package, so verify the exact engine on your vehicle’s VIN or door jamb booklet if you need precise identification.


How to identify the engine in your Cobalt


To confirm which engine is in a specific 2007 Cobalt LT, check the following: the engine code stamped on the engine block, the RPO code on the under-hood label (L61 for the 2.2L, LA1 for the 2.4L), and the vehicle’s VIN. The door jamb or under-hood sticker typically lists the engine type and associated options. If you have a service history, the paperwork will often state the engine specification as well.


Summary


The 2007 Chevy Cobalt LT offered two engine options: a standard 2.2-liter Ecotec (L61) and an optional 2.4-liter Ecotec (LA1). Both could be mated to either a manual or automatic transmission, with horsepower and torque ranging roughly from the mid-100s to the low-200s depending on the engine. To confirm the exact engine in a given car, consult the VIN, under-hood labels, or the original window sticker.

What are the most common problems with a 2007 Chevy Cobalt?


Common problems with the 2007 Chevy Cobalt include issues with the ignition switch recall, which can cause the car to stall or turn off while driving. Other frequent issues are ignition coil and module failure (leading to misfires and a check engine light), stuck ignition keys due to a faulty shifter, a failed timing chain tensioner (causing rattling), a bad gas cap that triggers the check engine light, and a sudden loss of electric power steering assist.
 
Engine and performance issues

  • Ignition switch recall: A major recall affected many models, with a faulty ignition switch that can cause the engine to shut off while driving. 
  • Ignition coil failure: This can lead to engine misfires and a flashing check engine light. 
  • Timing chain tensioner failure: A rattling noise from the engine, especially when cold, can indicate a failing timing chain tensioner. 
  • Stalling: Some models experience stalling at idle or when coming to a stop, with fluctuating RPMs. 
  • Electric power steering loss: A recall was issued for a sudden loss of power steering assist while driving. 

Other common problems
  • Stuck ignition key: The ignition key can get stuck in the ignition because of a failure in the automatic transmission shifter assembly. 
  • Faulty gas cap: A loose or failing gas cap can cause the check engine light to turn on, often accompanied by a fuel smell.
