pug Posted September 27, 2010 Share Posted September 27, 2010 Can i use a newer style overflow bottle instead of the big bulky one. I am converting over to the newer style winshield washer tank inside fender and the factory overflow bottle is in the way. Its a 1990 2.5. thanks Link to comment Share on other sites More sharing options...
ComancheKid45 Posted September 27, 2010 Share Posted September 27, 2010 Unless you convert the entire system to an open Cooling system i believe your stuck with that bottle... Link to comment Share on other sites More sharing options...
pug Posted September 27, 2010 Author Share Posted September 27, 2010 What is the differance in the bottles besides the size. thanks Link to comment Share on other sites More sharing options...
Geonovast Posted September 27, 2010 Share Posted September 27, 2010 All 2.5s have an open cooling system. Link to comment Share on other sites More sharing options...
pug Posted September 27, 2010 Author Share Posted September 27, 2010 So the bottle is different. My 98 with 4.0 has a cap on radiator and overflow bottle. Looks like same set up as the 2.5. I am confused on what a open and closed system is then.thanks Link to comment Share on other sites More sharing options...
MjPioneer Posted September 27, 2010 Share Posted September 27, 2010 Closed system utilizes a pressure bottle with a none capped radiator. Link to comment Share on other sites More sharing options...
Geonovast Posted September 27, 2010 Share Posted September 27, 2010 Closed system was only on 87-90 4.0s. Link to comment Share on other sites More sharing options...
