I have recently had the radiator replaced in my 1998 1.8 Vectra. Since then I have had no hot air coming from the heater. What should I do to correct it. Thanks

its prob an air lock in the heater matrix, to solve this is to bleed the system either through a bleed valve on one of the heater matrix pipes through the blulk head, or just pull the pipe off to the matrix and top up the coolant and replace the pipe when the water is coming through, or tighten the bleed valve, same as you would a radiater at home lol,,,,
