How do you replace starter 1990 gmc truck?

Answer 1

you disconnect your battery. Then you crawl under your truck, and locate the starter. There are two bolts that hold it in place, and two wires, a small one and a larger one. If it's your first time, easier to unscrew the bolts and lower the starter and unbolt the wires and observe how they are positionedand where they go as opposed to trying to feel abovve the starter for them. Also look out for spacers. Not all starters have them, but if yours does, you'll need to put them on the new one (between starter and engine). To install it, tighten wires onto new starter, and lift it into place. Lining it up with the holes in your engine block is tricky and hard on the arms. How I do it is hold it as close as I can and take one of the bolts and "feel" for the grove where it belongs. Once you've located one, tighten a few threads, and then get the other one located. After this you can take a break to relax your arm depending how long it took you to locate the holes and get a few threads into each. Dont forget to make absolutely sure that your wires are on tightly or they will come loose(nuts will fall off the threaded shaft, and you'll be cursing your truck isn't starting). You can use Loctite to secure them. email me if you have further questions on how to do this. By the way double check your cable from the battery to the starter once you are done to make sure it doesnt actually touch your exhaust manifold. I had another Chevy (84 half ton ) where I never thought about it and moved the cable, and ended up that the rubber cvoating melted, shorted to the battery till the battery melted and left me stranded on the side of the road.
