My Punto 60S MK1 1243cc gives off a distinct hot rubber smell after a run. No wild driving and the tyres are usually quite cool as are the hubs. Can't see anything smoking under the bonnet and can only assume that the exhaust is too near to something underneath. I have checked the cambelt and alternator belt which seem OK. Could it be something to do with the heater although this works fine and normal. Any ideas would be appreciated?
