Over heating in freezing temps-help
Hi guys, new here. I’ve found lots of threads about overheating but I’m wondering if someone’s ran into the same problem as me before. I’ve got a 2003 disco and when I’m at idle or low RPMs I start to overheat, fast, while this is happening my heater cuts out. When my disco is driving on the highway or up a canyon it runs just fine at the correct tempeture with the heater also working. I can be in freezing tempetures though and if I’m just rolling slow I overheat super fast. Anyone have any idea on if this is a particular thing you’ve ran into before? Thanks for help in advance.

Yeah, sounds low on coolant. The pump does not create enough differential pressure across the heater core at idle to pump through it (could be plugged). After bleeding the system using the bleed screw, let the system cool off then remove the expansion tank cap and rev the engine to 2000 rpm. Level will likely go down as the pump pushes coolant through the heater core
