Adam123 Posted July 2, 2017 Share Posted July 2, 2017 For some reason my expansion tank is low/empty even when I fill it up, there is no visible leaks coming from anywhere I have checked all the hoses and they are bone dry. The car has never overheated or anything like that...Any ideas? Quote Link to post Share on other sites
akyakapotter Posted July 2, 2017 Share Posted July 2, 2017 The way they work is it usealy pushes out extra coolant when its not needed then when the cars turned off it sucks it back into the system or when its needed. do you fill it up ? cheers nick. Quote Link to post Share on other sites
Adam123 Posted July 2, 2017 Author Share Posted July 2, 2017 I don't have to fill it up that often. It doesn't need that much anyway so from what your saying it could be right. That helped alot Cheers Quote Link to post Share on other sites
akyakapotter Posted July 2, 2017 Share Posted July 2, 2017 yeah bud mine fills up after a bit of a hammering then go back to it later and its sucked it back into the cooling system. Cheers nick Quote Link to post Share on other sites
