interchangeable engines

2.2 ecotecs are everywhere. Why not just keep it simple and replace it with the same thing?

I need to interchange my my engine to ecotec engines suck

Its an 11 year old Cobalt. It's not worth the massive expense and time required to change it to a different engine. What's the problem with your engine? The Ecotec is one of the toughest and most reliable engines out there. That's why GM and all it subsidiaries use it in just about everything they build.

I habe a 2007 chevy cobalt 2.2 motor.. Mine is going out what other motor can I replace it with that will work.. My cousin cause he can take 2 different motors and get them to work for mine... Please help

Don't waste time an money trying to make other motors work. The days of being able to easily mix and match engines are long gone. You need a 2.2 out of an '07 car to avoid problems with electronics, wiring etc. etc. If you want your car running again sooner rather than later tell your cousin not to get creative. There are hundreds of these cars in wrecking yards, finding the right engine should take about 3 phone calls at the most.

Was told colbalt 07 and 08 will interchange

I am needing to know if a 2.0 out of a 2007 Chevy Cobalt will interchange with a 2.2 out a 2008 Cobalt LT without having to change wiring harness and computer

will a 2003 saturn vue engine work and fit in a2006 cobalt

I would doubt it. The electronics will be different

The 2.2 Ecotec is only made to last about 80K miles. I have a 2008 Cobalt that has had 3 different motors in it since I bout my Cobalt new 12 years ago. The bolt holding the timing cover on will start to come loose and the tensioner slips, causing the timing chain to get loose and then started shredding the valves. By the time you notice the problem it is too late, you need a whole new engine. The last engine I tried was out of a 2006 Cavalier and it did not work, only fired on 2 cylinders of the 4. If it is a 2007 Cobalt, go with a 2007 or 2008 2.2L period. Anything else will cause more headaches than it is worth.

Where did you hear that the Ecotec 2.2 is designed to only go about 80,000 miles??

2005 Chevy Cobalt 255,000 miles on original motor and just went into limp mode with a slight tap on the top end of the engine! Still starts right up and will drive but wont go over 40 mph! Have parked till I find the time to find the problem and fix it! Cobalts have many many many issues but never had an issue with the motor till now!

It's a machine. Machines eventually wear out. 255K miles is pretty amazing. That top end tapping sounds like a timing chain problem. Definitely don't drive it till you find out for sure. It's easily repaired now, but if it skips the valeves hit the pistons and that will be the end of the car.

Thanks munron! Gives me a good place to start looking! This is the first engine like this I've ever had! I did the water pump prior to this issue but I used the specialty tool to keep the timing chain intact! But may have caused issues?

I've replaced just about every part on this car! New rims and tires, new suspension, all new front end parts, new rotors and brakes, new head light assemblies, new interior door handles, new ac compressor, new belt, new water pump and thermostat, new plugs, keep oil changed! It isn't the 2.0 turbo but it ran good till this issue! Did have a intermittent issue with the anti theft system!

I doubt that you caused the problem. As I said, things do wear out. And of course that may not be the problem at all. Really just more of a warning because it’s an interference engine which means if the timing is out valves and pistons will collide. I learned that the hard way when I ignored ominous noises coming from my ‘06 years ago. Still have it with about 160,000 miles on it . Your experience shows what consistent care and maintenance can do.
