No hot air

Hi all, ti was low on coolant, i topped it up and now it wont blow any hot air even when the engine is warm. Can anybody help?

Cheers

you'll need to bleed the cooling system, look in the knowledge base, someone did a walk-through I think

Park car on a hill or steep driveway. Turn heater on full blast. Before the engine reaches operating temperature, remove the radiator fill cap and adjacent bleed screw. Slowly add coolant/water until you see a steady stream with no bubbles flowing from the bleed hole. Tap and/or massage the radiator hoses to assist any trapped air bubbles. Allow engine to warm up slightly. Replace bleed screw and fill cap. Drive vehicle around for a few minutes. Allow engine to completely cool down and repeat the process about 3 or 4 times.

Be sure to use plenty lubricant because while tapping may work a hose is far more likely to respond to a massage...
