Is it normal for a 33's heater to be only mildly lukewarm? Like as in only just above ambient temperature?
So far to remedy it i've...
flushed the radiator,
flushed the system,
reverse flushed the system
and in desperation, i've even pulled the heater box out & flushed the core - passes water effectively, so I don't think it's that.
It all looks to be in perfect working order, but the bloody thing just doesn't heat... Even when the car is sitting at 80C, it's still not blowing more than a very subtle increase in temperature.
Any ideas? or is it normal for really woeful heat...?
