Bought an 06 solstice 2.4 with a hydro locked engine, bent rod, I have completely gutted this car, also have a wrecked GXP, complete car with a very low mile engine, plan on a swap, engine wiring harness in and out and dash. What parts fail on these cars and what should I address while I'm putting everything back together, for example should I change out both cores in the heat exchanger? they are most likely plastic, should anything on the engine be changed out? Plus I will have a lot of parts left over including a manual trans with all the associated components for an auto to manual change
