ok so i found a 2005 cobalt 2dr w/2.2l for sale, problem is that it wont start, if i buy it i will check everything and eliminate all other options, but worse case senario is i have to replace the engine. Just curious for any of you guys who have replaced a 2.2, is there anything i should know about this car/engine before hand, any common hang ups or problems. Swaping an engine doesn't scare me as i used to be a mechanic, just not familiar with this car/engine.
any info would be appreciated thx.

just realize this is probably the wrong section, can mods plz move, thx

i would swap the lnf engine into it...if thats possible. which it should be, its the same car

this is the right section. technically its a question about the L61

but yeah. try to get a s/c or lnf in there.

I dont believe it is as easy as just swapping it in. ( LNF or LSJ that is) .

DarkCobalt13

I think to do the LNF, your talking rewire the entire car almost..... this dude just wants to know if there would be any prob with dropping and identical motor in so the car will run.

To answer your ? As long as you know what your doing, it should be fairly straight foward. Never done it personnally though

2.2 to 2.2 is no problem. 2.2 to LSJ or LNF is not going to happen.

Jackalope

Not without a lot of supporting stuff.

alleycat58

LNF I don't think is possible at all. LSJ is going to end up costing more than the entire car is worth IF it's even possible to do.

Jackalope

QFT!!

still u dont want to swap the old engine out if there r no probelms with it.

do u know wats wrong wit it? could b so many things.... fuel pump, electrical, etc does it crank?

Anything is possible. I'd swap the LSJ motor into it and tranny. Just have to gather all the supporting mods.

LethalSS

jus going with the odds.

Make sure the engine is from the same year and the same model (2005 2.2) and you should have no issues.

blackbolt89

actually, i'm surprised no one mentioned swapping in the 2.4. same tranny-ish lol, same mounts, same intake. i'm not 100% but i wouldn't doubt it would be a relatively easy swap.

when i get it later today i'm gonna do all the checking that i can think of because i don't think its the engine, pretty sure its electrical, could be as simple as a relay or something. i'm getting it for a good enough deal that i don't care what the problem is, it will still be able to turn a profit if i flip it, or a damn good car to bum around in for ridiculously cheap.

and ya i meant swap the 2.2 for the same 2.2, and what i was referring too for problems or complications is for example, when i changed the clutch on my s2k there is 1 starter bolt that is f***ing impossible to get at, and you spend like 2-3 hrs on that damn bolt. just wondering if i will run into anything like that.

thx for the responses!

also the problem with the car(from what the last owner tells me) is that even with a new battery, fully charged, the engine wont even crank. i wasnt able to try when i went to look at the car because the battery had died and frozen cuz it was sitting outside in canadian weather since fall. he says all the lights come on and there is a small click or tick. he said he checked the starter and it was fine, he couldnt figure it out so he gave up and bought a civic...

can u guys gimme an idea of what to check on these cars. i have some idea as i checked some of the other "car won't start" threads here. and have never had a problems with my 07 ss s/c when i had it besides crank sensor. thx for any help

id do a 2.4 bottom end with a L61 head if your going to boost

Edubs

There are a few GM techs around the board. Keep this bumped and one of them will eventually come across it. They'd be your best bet. Sounds like a wiring/ignition issue to me. May even be a simple fix...

He's just buying it cheap and then hoping to sell it for a profit. He's not building a race car.

to the people who are saying swap to an LNF/LSJ or LE5....dont even try. Its not that simple. The three engines all use completely different electrical systems, and to swap engines, you would need to swap every electrical device on the car, including gauges, indicators, ABS sensors, airbag sensors, etc. Everything would need to go. In addition, there would be a LARGE amount of custom work to bolt it up to the F23 trasmission as well. The LE5 would do without the F23 issues, but the electrical end alone would be completely ridiculous. It seriously would probably be cheaper to buy the LNF cobalt than to swap an LNF in to an existing cobalt..

to the OP: make sure that if you DO end up swapping motors, get an L61 of the same year, as the 07+ uses a different PCM and has a cam sensor amongst other small changes, and will not work with your '05 PCM. I believe the '06 also has a minor electrical change opposed to the '05, but they share a PCM, so an '06 engine should still work for you

thanks for the reply's, i hope its electrical. if it is then i should be able to find the problem pretty quick and get it up and running,(personally i love electrical work). ya i knew there was a difference between 2005-2006 and 2007 pcm. ill probably find a 05 engine. my question is if i am just swapping the motor out and putting the same year engine in, will i have to do any type of recalibrating for any of the electrical components, just because its a different engine that came with it? havent done any swaps on newer vehicles with all this electrical crap, and i was a Heavy equip. mechanic so the knowledge i have doesnt always apply here lol

to the best of my knowledge the only thing that would need to be done electrically is a crank relearn. Another member would have to give you the details there tho, since I've never needed to perform one.

Sentry

Also, before you go swapping motors that could potentially have more issues than the one that's in it, make sure that the engine is officially unusable. It could end up being something rediculously easy like a fuse. I'm sure you know that though. Might be a good idea to have it checked out before you try and swap anything.

07vrsssc

so, i just picked up the car. and we had the battery hooked up briefly in order to get it into neutral (auto) and i turned the key to start and there is nothing, didn't even hear the starter trying to engage or selenoid clicking, i think there was a feint clicking noise like a relay. so when it gets lighter outside ill go figure it out. correct me if im wrong but there is a 2nd fuse panel on the passenger side foot well? cuz if there is than the previous owner didnt know about it and therefore didnt check it out. keeping my fingers crossed its something simple. also the ignition cylinder seems to be sticking, its hard to get the key in/out and isnt smooth when turning to start, that could be the problem right there. haha i love electrical problems, so fun! (i know im retarted for saying that)

07vrsssc

so because of where i am, i currently have no tools to use, besides a multimeter. so far im pretty sure that the engine is seized. all fuses and relays ok. wiring seems good in most paces accept for the butchering of the stereo wiring (think he must have had an aftermarket stereo). getting power to the starter and its engaging however engine is not cranking at all. i don't have any wrenches or bars or else i would just try turning the crank. so far this is my best guess. also there is an oil leak somewhere, dripping down off the oil pan and there are a few(very few) metal flakes on the dipstick (like 1 or 2, about the size of a grain of sand).
