No heating in my 182.... :-(

[lambo7]

My heating was ok until I had my radiator changed........i have just changed my thermostat (just in case) and still no warm air.......I must admit once or twice a week I get the heating working but most of the time its cold air.
Could anyone please advise me...????
thanks
