93 Geo Metro
I recently replaced the water pump on my 93 Geo Metro, 1.0 and of course you have to disconnect the belt tensioner. My question is, are there more than 1 spring that hooks up to the lever that the belt tensioner bolts to on the front of the block and where does the second spring connect to? I would really like some help here as it doesn't show anything in the chiltons manual, poorely published whoever wrote it. ty

RE: 93 Geo Metro
Are we talking about the belt tensioner for the accessories or the cam timing belt?

cam timing belt, I know that there is a spring that hooks to the belt tensioner plate down by the crank sprocket but then there is a smaller spring that is called, a spring damper, that is the one I want to know where it hooks to. it kinda is u shaped but spread apart some. hope you know what i am talking about.

RE: 93 Geo Metro
Here's what I came up with floating around the web. About half way down the page there's a great / clear shot of everything that should be there on an actual engine, not a diagram.

http://geometroforum.com/topic/2232748/1/

BTW, someone in that forum mentioned there were two slightly different versions of that engine with the 93 being right in the middle. There's details in there depending on rounded or squared off timing cogs being the clue. No mention that I noticed on tensioner springs, although there may be a difference if you search for say a 1995. (replacement engine at some point?)

Now, back to your original question.... a damper spring is usually something added to the larger spring for the sake of vibration or unwanted oscilations. (noise issues?) Typically one spring is inside the other so there may not be a second post or hook to mount this on. At 500% zoom on that picture I think I can see this may be the case for your engine.

Hopefully you installed a new timing belt so the specs for tension are right on the money.

thank you for researching that, I really appreciate it.

RE: 93 Geo Metro
yep it's me again, wanting to know if one G10 geo metro motor which is a 5 speed manual transmission and the other G10 motor being an automatic, would I be able to put the clutch and pressure plate on that G10 motor which is an automatic. I call the auto parts store and had them count the bolts for the pressure plate, they said there were 8 of them. On the motor I just got has only 6, will the pressure plate still bolt up to the new motor? I know that sometimes they offset bolt holes just for that purpose. would like to see some pics. or even some information, thank you.

RE: 93 Geo Metro
I think you are confusing the flywheel bolts (to the crankshaft) with the clutch plate bolts. In order to make this swap you would need to remove the torque plate (that's what they call the flywheel on an automatic) and install the flywheel from the other engine.

There may be other minor variations between the two engines but the general thrust is to swap everything so the replacement is the same as the original.

What I would do if I were in your shoes is call my local junk yard and pose that same question. They have something called an "interchange manual" that is the Bible of the salvage industry. It will tell you what fits and what doesn't fit plus any modifications necessary to make things fit if it's possible. (flywheel swaps, manifold swaps, only certain years, etc)

Let us know how you make out.
