Heater not working after waterpump replacement

Hi, have a Peugeot 207cc which is almost six years old. A few months ago overheating light came on dash and temperature gauge shot straight up, I let the car cool down and added water, took it to Peugeot who fitted new water pump. Now when I put the heater on its luke warm and temperature gauge stays on cold, heater smells like sweaty socks. Checked anti freeze and it was on minimum so I topped it up and called Peugeot who can't get it in till next week and will charge £90 just to look at it. Any ideas what it could be and whether it's ok to drive till I can get it in.

I suspect an airlock. Try taking the pressure cap off the reservoir, then starting the engine and running it fully up to temperature (until the engine radiator fan comes on). If the thermostat is opening properly that should purge the cooling system of any airlocks and you can then top it up, replace the cap and (if all is otherwise well) it should run normally.

Improves on the 206 CC in every single area. A quite impressive coupe-cabriolet. Best of the CCs this size.
