hope you can see the pic as ive had problems here before with them. as you can see the flow through the radiator is virtually non existent . car does not over heat on a journey and non of the warning lights come on . has a new aluminum radiator , water pump , fresh coolant , working thermostat and as far as I can tell no blockages although it looks like it might . after a drive the top hose gets hot like it should but the bottom hose which has a spring in it is soft and barely warm when I touch it . ive burped the air out the system also . its a factory 455 . so now I really don't know where to go from here any help guys thanks .
