Help 146 heater problems

Hi all, Can anyone suggest anything for my Alfie's heating problem? The engine is always very stable temp wise but the heater will only blow lukewarm - never hot. I have flushed the cooling system but no improvement. I am hesitant to change the thermostat without knowing it could be faulty.

Thanks in advance!

Re: 146 heater problems

Could the heater cable have slipped on it's pulleys?

If it's any help, I had my thermostat replaced yesterday as the engine temp would go to 90, then fall to about 60 without warning then if I was lucky, creep up to 70 then go no further. Also, fuel consumption increased. Thermostat replaced (£29.50 for Quinton and Hazel part from a local Motor Factors and £20 to fit). The heater temp is now lovely and warm and fuel consumption has dropped again.

It could be that your temp sensor is also broken hence saying it's stable; but I am more prone to think it's the heater cable. Swine of a job as the majority of the console has to be removed to get at it.

Hope this helps?

If it were a 33 boxer I'd vote for the heater core to still be partly blocked despite the flushing.

Re: 146 heater problems

Partial success! Indeed it was the cable, the little plastic clip holding the outer cable on the heater box has broken, hence no adjustment :-( Couldn't manage to get enough of the dash off to give me proper access but I did manage to get my fingers on the control at the box end and move it fully to hot :-) I guess I'll put a window down if it gets too warm now lol. Many thanks folks!
