Hi yet another newbie! I got a 1996 imported wrx. Problem is recently when it is ticking over and heater is on hot it blows cold even though engine is warm, when you rev a little gradually gets warmer. Initial thought was head gasket but no obvious signs of this. Anyone else experianced this or got any idea whats up with it?? Any help much appriciated. Thanks

 

Hi, Have you fitted a new rad or pipework, disturbed the cooling system in anyway?

Could be an airlock or a blockage

 

hi no not had anything done with rad or anything recently

 

Perhaps the linkage on the heaterbox is disconnected or the motor/position sensor is corroded or stuck?

Cheers Iain

 

could also be a warning that the water pump isnt shifting as much water around for some reason

 

How long you had the car, what do you know of it's history?

 

many thanks for replies. now u have said it, it would make sense. hopefully its just that dont want scooby dieing!!
