JRLinTN Posted July 13, 2016 Share Posted July 13, 2016 I am looking for a radiator overflow bottle for my 1988 Comanche. Am I correct to assume that all engines except the diesel use the same bottle setup? Is there and OEM like reproduction out there? If not is there a replacement that will work and look right. Thanks.

fiatslug87 Posted July 13, 2016 Share Posted July 13, 2016 The 4.0 has a pressure bottle http://m.quadratec.com/products/product.php?pid=51216+01 or if you want fancy http://macsradiatorshop.com/catalogsearch/result/?q=Jeep The 2.5 has a traditional overflow http://m.quadratec.com/products/product.php?pid=51216+02 Link to comment Share on other sites More sharing options...
ScottJeep Posted July 14, 2016 Share Posted July 14, 2016 Used the Quadratec bottle when I was running the closed system. Even after replacing it with a new one it cracked. Have been using the 2.5 style bottle shown with my open system. Works fine. I have a cowl induction cold air so the 2.5 fits perfectly where the 4.0 air box was previously with LOTS of room to spare.

JRLinTN Posted July 14, 2016 Author Share Posted July 14, 2016 Thank you both your replies. I ordered the bottle for the 2.5 at the link provided. I replaced the original engine with a Chevy 350 and it is not a pressured system. Restoration and modifications to this has been a ten year project. Paint is on. Interior done. Finishing up the detail stuff now. I will try to post photos when done. End of summer.....hopefully. Randal Link to comment Share on other sites More sharing options...
