Hi, have you checked if the car is comming up to temp? ... It may be the thermostat has failed open or the radiator expansion bottle pressure cap has failed.
If you need to "bleed" the matrix, on some models there is a vent cap on the return hose in the engine bay, otherwise its off with the top hose, with the heater on hot, fill with coolant until some comes back out, then reconnect the hose and run the car until it comes up to temp with the heater on full then carefully release the expansion bottle cap (dont burn yourself) and fill the expansion bottle ... that should sort it out. When cool topup again.
I'm sure its only one of several ways to bleed the matrix.
Hope it helps
Why is it the older I get .... the better I think I was ?
