Ok, I'm going to look at a lady's Geo Metro on Sunday - not to buy, but to fix for her. I think she has a bad water pump bearing. She does NOT know what the trim level is, but she says she thinks it's a 1.0L (though she sounded unsure).
Before I back myself into a corner and agree to work on it I need to know a few things.
1) Does the car use a timing belt or a chain?
2) Is the car's hardware metric or standard?
3) Does removing the crank pulley require some special puller/tool/method?
4) I'm assuming the waterpump location is similar to that of a Honda - driven by the timing belt and behind a plastic shield that is behind the crank pulley. Am I correct?
The water pump is driven by the alternator belt, but the pump extends behind the timing cover, so to get the pump off I'm going to have to remove the crank shaft pulley. There is no obvious way for me to hold the crank pulley still on this engine. It is one large 17mm bolt in the middle, but nowhere to hold the pulley. I'm going to try getting the crank pulley bolt off today, and if I can't, I'm not going to do the water pump.
