I have just installed a new 3 core in my 65 coupe, and for some reason everytime i stop the engine, it spits a fair amount of coolant out the overflow hose... Is there an overflow bottle that should be fitted, as all the pics i have seen do not contain anything except a wiper bag... Just trying to search the web for some pics.. but they all seem to cut that side of the engine out for some reason... maybe it isnt too pretty !!! but as long as it functional.. any thoughts appreciated.. spending alot on an engine to have it overheat is not what i want... Thanks in advance.. ( I have a 14" flexie and a 12" thermo to help keep it cool)
