How much would it cost to repair a Ford Windstar, & should I bother?

i think you would be better off buying another. thats gonna cost 1000s

There is an outfit called Jasper that specializes in rebuilt trans and engines.  I'll bet you can find them on the 'net.  Their prices will be as good as you'll get, and you'll still have to pay for installation.  I strongly suggest you follow jennifer's advice, especially since there are better deals available these days.  Recent model Chrysler minivans have some pretty attractive features.  Check the NADA [Blue Book] website for the value of your Windstar and then decide if the repairs are worth it. 

Is it a 3.0 liter or what size engine. That makes a differenceWhat part of the country do you live in that also matters because some states are higher than others. New York HIGH where Mississippi LOW. If you have a 3.0 and live anywhere in Georgia, Alabama, Mississippi or Tennesee I have a 3.0 that came out of an earlier model Windstar but a 3.0 liter is a 3.0 liter as long as the cam confirguration is the same (duel overhead cams DOHC, single overhead cams SOHC or the regular single cam with pushrods engine) Most have the regular. I will take $100 for the engine because a guy bought the truck that it was going in for "muddin" before I installed it. He wanted a bigger engine. As far as the radiator you DO NOT have to scrap it. You can put the radiator on its back with the tranny lines pointed up with a  long rubber hose on one of them going into a jug of some type. Then you use compressed air to blow all the bad fluid out of it and then you put a funnel on the end of the hose (or a mustard bottle and squirt fingernail polish remover (acetone) into the line and let it sit for a day. You continue to put acetone in it until you see it come out the other line. Let it set like that for a day or two and then blow out the acetone the same way. The radiator will be fine at that point.
