any one know what year models that a crank from a 2.2 eco tec are interchangeable ... i did find out that the rods and mains of the 2.4 and 2.2 in some years are the same but im more concerned with the stroke ...i found a 2005 2.2 ecotec with a cracked block but runs with no noise ..(water instead of antifreeze ) go figure... mine is a 2007 2.2 ive been researching and cant seem to find any thing as of yet ... thanks in advance

 

Mitchell Estimator says the same part number 2005 Cobalt LS 2.2L and 2007 HHR LT 2.2L.

You will need to relearn the crankshaft sensor.

 

thanks donbrew guess ill be buying the 05 2.2 and do some engine gut swapping....

 

well that 05 engine was a bust i went this morning to buy it and the dang thing was setting out in the weather (uh oh ) so i attempted to see if it would turn over ( guess what nope) the plugs were out and the thing was locked up tight...he tried to drop the price and say take it apart clean this clean that yada yada .... nah i dont think so....

seems im still looking ...fingers crossed

 

Check your local junkyards, tested and warranted used engines go for $500-$800.

 

yeah i have several looking through their inventory for me..

 

i know its been a while but here is an update i found and bought a 2007 2.2 for my hhr it came out of a 2007 cobalt just needed to swap the thermostat housing and the exhaust manifold and block that coolant line near the fill line... not sure what that was for ...but she is up and running great and i love it ... still some little odds and ends to tie up but its been a fun project... i do however have another problem of sorts but ill search before i start another thread but for all the info thanks guys...this is a great place for information...

 

That plug you mention was for the coolant recovery pressure tank on the Cobalt
Glad it is running great!

 

me too oldblue me too now if i can just figure out the tranny trouble sheesh...

 

Double check your ground wires and TCM connections
