Cold heater on idle
#1
My heater is warm when driving. But when i run the var on idle the temperature drops to 80'c and after a little time down to 30'c .  And no heat in the airheater.
Coolant level is ok.
How do i bleed the wather system? 



Maby change wather pump. And thermostat if bleeding does not help.
Any ideas????

I would suspect the thermostat 1st.If the vehicle is old & not been well maintained,the impellor on the pump may be eroded due to cavitation & lack of coolant addiitive.

2009 berlingo 112 000 km on the wheels. i have not changed anything on it yet. just filters and a steering link.
so maybe its time to change the weather pump and thermostat then.

I thought that impellors were all plastic these days ?
A mute point really as the timing belt is likely due anyway - an easy way to find out for future reference perhaps ( hint ).

I too would suggest the thermostat as the first port of call.

Happy new year to all .......

Is this a non-AC model?

If so, then the thermostat is the most likely culprit.
On Non-AC models, the heater is just a small radiator on a parallell loop to the normal radiator.
(Hose connects to the thermostat housing or near it, but on the other side of the thermostat than the top radiator hose)
Water is always circulating through this secondary radiator, but because of small size and little 'heat loss' it doesn't impact engine temperature all that much.
Now, if the water is always circulating through the big radiator up front... even when the temperature drops below the point when the thermostat should close... then the temperature keeps dropping like nothing else...
