I have a nice little ke55 and a few months ago the water pump went on it and i had a new one put in. That went well for a few months then it started getting hot again. I've flushed the radiator out, filled completely with new fluid, put on a new radiator cap and put in a new thermostat and gasket. but it looks like fluid is going into the overflow bottle and not going back in because when my car is dead cold my radiator is low on fluid and the bottle is full. driving on the highway is fine cause the air flow keeps it cool but as soon as i slow down the temperature gauge raises fast.
additional - the radiator cap is for one with a different kind of overflow system i think. can't for the life of me think of it's name now. but i only have the one hose going into the overflow and the fella at repco gave me a cap that's meant to have a overflow with a second tube coming out of it.
any thoughts? thanks
