fiatslug87 Posted October 27, 2019 Share Posted October 27, 2019 If you want to never have to replace that plastic tank but want to keep the closed set up you can get one of these http://macsradiatorshop.com/replacment-jeep-radiator-fill-tanks.html Pricey but very well made.

fiatslug87 Posted October 27, 2019 Share Posted October 27, 2019 Yes, I run all of mine to 2.5L overflow tanks. So technically it is not a closed system. Link to comment Share on other sites More sharing options...

buxmj Posted November 1, 2019 Share Posted November 1, 2019 I always bought the cheap replacement caps and should have bought the volvo cap. When the tank sprung a leak at a seam several years ago I splurged and bought a Mac's, won't ever have to worry about either now. Buck. Link to comment Share on other sites More sharing options...
