I changed the water pump and now I cant get the timing set on 91 Geo Metro?

Answer 1

use 17 mm wrench to put crankshaft at top dead center, of course you have to remove belt pully and timing cover, there is a dot stamp into the bottom timing belt pully, and there is a projection that also lines up with the dot. and if you observe the area directly above the crankshaft timing gear of pully , there is a vertical projection that is about a 1/2 in long line up the dot or projection with the line.

Second there is a indent in the top of the camshaft[timing cover and you should notive a line or something on the camshaft gear it needs to line up with the indent on the timing cover. When you have both lined up, make sure the idler pulley is loose. put timing belt on and tighten belt with the idler , belt go to the left of the pulley. there should be a spring tensioner with a long 10mm wrench size , loosen bolt on pulley and tighten belt and recheck you timing marks so that they are in time. use 17mm wrench to turn over by hand to make sure everything turns ok . replace timing cover and install crank pulley and water pump pulley and water pump belt first and then air conditiloning comp. belt.

PS I have found it easier to work on it i put a floor jack under oil pan and then remove the two bolts that are the passenger side front motor mount , so you can get to the bolts in the crank pulley and the timing cover from under neath.

Also it is a lot easier to work on the car it you jack up the front and put jack stands under the body just behind the front wheels. I know i own 3 geos and

have been working on them for 4 years. Larry Stephen Adrian Oregon
