Hii,

I'm driving an 89 Dodge 250 Van it has a 318 and im assuming a 727 tranny (maybe a 904). The van has overheated on me twice while I am just driving it around, I have just been waiting for it to cool down then adding water to it. This has worken, but im not sure where the water is leaking to. and also feels like overdrive is not working, I think it has overdirve though im not positive. I am positive its not going into it now. Is there like a vacum line for overdrive or a cable or somethin?
The van has 56,000 miles on it.

thanks for any help

if it is over heating and the water isn't going anywhere it might be a bad head gasket. I would check with a pressure tester on t I have seen some very slow leaks before.
and on the 727 or 904 they are both 3 speeds with out over drive

You would think if it's a head gasket, and the coolant was going into a cylinder, you would see white smoke. It may, however be leaking out of the block and slowly evaporating on the hot block or exhaust. You would think that you would smell something, if that was happening, though.

The Van overheats everyday this week, afer it overheats i throw about 3 gallons of water into the radiator and it rusn fine, i dont know where the water goes. I dont see a huge puddle after it sits, I guess the engine could be burning it off or boiling it out, so i flushed the cooling system today and put in some prestone with some fresh water. I'll find out tomorrow if it leaks.

About the overdrive thing, today i was driving it and it kicked into overdirve kinda hard, but only once while driving it all night, seems to only go into overdrive when the engine is overheating. or really warm.

Thanks

I also used to own a 5th avenue with a 904 tranny, it had overdrive. a 4th gear.

wow that is a crazy amount of water in there
you are almost emtying the complete system and well if you didn't have a head gasket bad before i am sure you do now.

pressure test that thing to see where it is going
