ABL8R Posted November 8, 2021 Report Share Posted November 8, 2021 Hi I bought an S1 Eclat in the summer which looks great cosmetically but needs a lot of work under the surface, not least a new chassis! It is off the road in my garage for now while I wait for a new chassis but as the temperatures up here in Scotland start to drop I am beginning to worry about the coolant. The PO just put water in it. The expansion tank has a thick layer of rust inside. I will probably replace it for an alloy one but meantime I am wondering if I should drain the water and replace it with conventional antifreeze. I have read about the waterless stuff which is very expensive if I am just going to drain it in a month or so when I take the rad out for the chassis swap. I could also just drain the system now and leave it dry but I worry that could cause bigger problems which channels getting bunged up. Also, forgive my ignorance, but can the S1 run on unleaded or is lead replacement recommended? any advice appreciated chris Quote Link to comment Share on other sites More sharing options...
