I need to replace my starter on my 1990 GMC Jimmy 5.7l. I will only have a couple of hours to get it done has my vehicle is a daily dirver and i will have to use my vehicle to go get.

I have looked them up and they are showing a large or small opening. I was wondering if anybody knew which one I will have on my vehicle.

Thanks,
Dan

 

Take your tools with you and change it in the parking lot (if you can get away with it). Whenever there are options for parts without specifications as to where they were used, I always take the part into the store with me to verify an exact match.

 

make sure you unhook the battery first

 

Replaced the starter and all is good.
