Engine/transmission removal and replacement

Hey everyone.

I'm working on my buddies 3 cylinder 1997 Geo Metro with a standard transmission.

He threw a rod and when he purchased the vehicle the previous owner included a 1995 Geo Metro engine and transmission in with the deal.

Upon receiving his vehicle the engine and transmission were removed but also came seperated, along with the new engine and transmission.

I have swapped over all of the old sensors and necessary bits from the 97 engine onto the 95 engine and I am ready to drop it in.

I am wondering if I can put the engine and transmission in while they're mated.

I've done some reading and it sounds like you have to remove the crank pulley and separate the engine from the transmission to get out. Though, I havent been able to find anything where the transmission and engine were removed at the same time.

Thanks for looking.

I pulled a tranny in and out several times putting in a clutch and I can tell you to be sure and use a quality clutch kit. The cheep one I used kept damaging the splines when the input shaft was banging on the clutch disk trying to get the alignment. Yes you will have a tight gap and taking off the pully is necessary. This may be why most mate the units first.

Warning I used to own a 95. Some 95s are actually the same as pre 95 on emission stuff. You may have a late 95 that is the same as a 97 but in my opinion doubtful. The 96+ all have a crank sensor. The pre 95 do NOT have a crank-sensor. If the 95 engine does not have a crank sensor next to the pully I would not do the swap. Just my two cents. Good luck

I had similar thoughts. I think your 95 is obd 1 (I could be wrong though, I'm not sure of the second half of 95), whereas the 97 is obd2, I think that might mean different sensors and harnesses.

Did you swap the the whole intake and distributor over? Was the water outlet the same?

As far as dropping in the engine....much easier to separate and mate outside of the vehicle.

I cant remember exactly but I don't remember having to take much off of the 3 cylinders to get them out while they are mated. I think I pretty much just disconnected everything and yanked it out....exhaust, popped the axles out (remove two lower strut bolts), vac, fuel coolant hoses, (even quicker if you plan on replacing all the hoses...snip snip), mounts....

The only minor hang up I have when doing it this way can be the rear motor mount, I think I wait to bolt the starter and alternator back up until I have it dropped in, to provide better access from above to that mount.

95 is OBD1 so a true swap requires swapping the oil pan and pump for the crank sensor. 94 had half and half of the emissions equipment, 95 should be the same all the way through. 3 cylinder engine will pull with everything attached, the 4 cylinder requires removing the pulley to gain extra room.
