i'm in so.cal, just trying to get my durango together.more later

 

i need some advice regarding my radiator. seems my water is backing up in my resevoir, plastic one around my radiator. any ideas why?

 

i just remembered why. about two weeks ago i was having problems with it losing water, and over heating, found a little leak, and poured aluma seal,to my radiator. plugged the hole, butnow i'm assuming it plugged up everything. can anybody relate. i havent used that stuff since the early 70s.

 

Welcome to DF! Please add some info about your Durango so we can move this to the appropriate section to get your answers. Year, engine size, miles, etc.

 

As the engine heats up, coolant expands. It needs to go somewhere, and that's what the overflow bottle is all about. Level should go back down as engine cools.
