depending on the year of the van I imagine that the area would differ but I have a 1993 astro and the jack is at the back so if you open the back passenger door it should be right there you unscrew a knob and it will let you remove the panel and the jack and all the other stuff should be in there hope this helps
Yes.
The Astro does not have a flywheel, it has a flexplate. To remove it you have to remove the transmission so you can unbolt it from the crankshaft.
The cost to replace a 1995 Chevrolet Astro van will vary depending on the labor costs and the part cost. The price for the starter starts at $46.00 dollars.
The jack in mine is located by opening the back door and on the right side there is a panel that pulls out. It is held by velcro so give it a tug. If you find a jack in there you will find it near useless as well. But you can probably get one that really works and store it in there for future use.
I have ran 275/60/15 on ours all the way around. Front would rub if you hit a hard bump while turning to the fullest extent. I favored the 255/60/15 the best.
