hi,
the engine started to steam up today near home, 1/2 mile away , coolant level warning on, but the temp gauge did not move.
got it home and notice steam coming up from the back of the engine bay.
once cooled i poured about 6 litres of water in the expansion tank and noticed it was pouring out at the back of the bay on the right hand side (looking at the engine).
i had a good look at the top hoses but couldn't see anything so i think it could be lower down.
does anyone know what it could be?
thanks
