We have a 1997 Geo Metro with the 1 liter 3 cyl. I found a 1992 motor, 1l 3cyl in good shape. Both are standard trannies. Will these year models compatibly swap out. Or swap out easily. Any mods that may have to be done. All help appreciated. Thanks!

HELP FOR CHANGING SPARK PLUGS IN MY 1998 CHEVROLET METRO LSI by r21gloria3

I AM WANTING TO REPLACE MY SPARK PLUGS, BUT HAVE FOUND THAT I NEED SOME SPECIAL TOOL, AS THE REGULAR TOOLS WILL NOT GET AROUND THE SPARK PLUG THREADS. IT LOOKS AS IF WAY DOWN IN THE CYLINDER, AT LEAST 5-6 INCHES DOWN, THERE ON THE PERIMETER OF THE SPARK PLUG IS A RUBBER COVERING, WHICH DOES NOT ALLOW FOR ITS REMOVAL. HAS ANYONE ELSE HAD THIS EXPERIENCE?

Hi bitmaster,
I just went thru the same project and found that those two sets of wires are indeed ground wires, their purpose is to provide a ground for all of the sensors in the head and intake manifold that require a grounded circuit.
You might need a mirror to see where they are mounted to on the back side of the intake manifold just below the air intake base. You need 2 bolts about 1/2 long not sure of metric bolt size but a 10m wrench fits. There is one on each bottom corner on the throttle body.
Good luck

Coach,
 
  Thanks! I tried a couple different things after getting recommendations from one other group, and found that having one attached to the firewall and one on the post where you mentioned seems to work best. I will add your input to the list if things go wrong. As it stands, I took the little Metro for a spin around the block for the first time since we switched out the clutch, and it runs! I'm really grateful for all the help I've had working on it.

My Geo Metro gave me this same problem just the other day, BUT in it's defense I did let the gas tank get below one eigth full, with NO dry gas additive, in 10 degree weather (less if you count wind chill then it was really colder) and had not started it in two days ! Whatda ya expect from an old eco car ? I mean we can only abuse them so much before they retaliate ! A little dry gas in the tank & some dumped right onto the carbeurator, and a hair dryer on the spark plugs for a half hour and she finally started. When I put a new engine in her next spring I'm also putting in a engine block warmer (frost plug kind) for a measley $20 it'll be well worth it. Otherwise you gotta kepp these fine old Geo's in a warm garage if it gets below 20 degrees. And thats my two cents guys !

Find Me An 97Geo Metro Engine ! by suz13

I know you all have talked on this site before about where to get an engine but I can't find the thread. I intend to spend some of my tax money this March putting a new engine in my Geo. It can be a used engine w/ under 50G miles on it OR one of those new Japanese jobbers (i think i can afford it). Locating a "USED" engine with my old mechanic is taking too long so I'm leaning toward just getting a new one. Afterall, I've replaced so many other major things in my Geo I might as well consider it a slow rebuilt top to bottom, I'm STILL spending less per year than car payments and gettin 39mpg on my commute. Can anyone tell me how to buy the engine ? Do I need to say anything to my new mechanic about where to get the engine (he is a trusted affilaite of my employer and reputable) or should I just see what he says & compare it to what you guys say ? Or should I attempt to buy it myself & have it shipped to him ?

First check the bat. termanels and or clean them. Know one can know this answer, as it is an intermit problem. I'm sure as you know, this is sometimes a warning before leaving you broke down. If it is not the connection at the termanels, it could be a bad possative connection attaching to the starter selonoid. Most likely the starter selonoid is going bad, and is giving you its warning now. It is a bolt on part,of the starter. Its very common for it to go bad and blame it on the starter. In short, he selonoid job is to engage the starter gear in to the flywheel and trigger the starter to spin at the same time; it is electra mechanical! The clicking sound is coming from the week selonids electromagnet, making it unable to engage the flywheel; in turn the starter will not spin. So if you brake down, dont give up and call that tow truck, try turning that key about 50 times eventually it will give you 1 last start; and if that does not work, hit that starter with a wrench or a small hammer, then try to start it; this will get you home! I hope this helps you!

Hi zenden and thanx for your answer.
 
One thing is sure, it's not the batterie: it new from 2 day ago
Maybe the termanels? (is there a simple way to check if it's that?)
And for the started selonoid
(srry, i'm sure it gonna look stupid, but i realy bad in mechanic..) So the selonoid is a different part of than the starter. Cause my starter have been changed only 6 month ago... (do when we changed the started, the selonoid is also normaly changed??)
 
thanx for you help,

Yes! the solenoid almost always comes with the starter 97% of the time. I just read your 1st post about this, so please excuse me for that. The bat. was changed so most likely the connections are good. There are many things that can cause this, but I would be focusing on that starter selonoid even tho it was replaced. The odds are high that this is going bad if you where not having this same trouble before you replaced the starter; especially if the one that you bought was not new; or had a lifetime warranty on it. Re manufactured starters come in 2 grades, the one with the short term warranty is processed quickly on an assembly line; No one is held responsible and corners are cut. At times I have found that these starters will not work at all when purchased. Often they only last for 3 months.
  If you have noticed this problem before the replacement of the starter, then I would be looking for a bad connection in the wiring system; AS IN: a bad ground connection where the negative wire from the battery connects to the engine; or possibly a faulty ignition switch witch is inside the steering column. I hope that this info helps you.
PS: If the headlights dim when you here the clicking sound then there is a bad connection between the battery and the engine! On the positive or negative side!
