My Td5 has a issue regarding the heater. After a couple of mins of driving the heater warms up nicely but if I park & leave the engine running the heater gets cooler & cooler until its just blowing cold air. If I drive off it will warm up again
It doesnt matter if Iv driven 10 or 50 miles it does the same.
Any ideas?
Thanks Ian

It's normal. TD5 engines do run cool especially on tickover. Get yourself a rad muff to restrict air flow in the winter

Great many thanks

Take the viscous fan off for the winter and/or fit a leccy one.
The heater matrix is enough to cool the TD5 at idle.
