Discovery II 140,000
Water pump leaked so it was replaced it 2 weeks ago.
But no hot air from heater.
So took head off and had it checked, Pressure test ok but needed a light skim.
Replaced 1 hole gasket with new 3 hole gasket,
Fitted new thermostat and radiator flushed system out with hose.
Refilled and started the temp gauge goes up to mid point and holds but still no warm air from heater.
Hoses from heater. . . . . one side hot. . . . the other side much much cooler.
New radiator, top hose hot, bottom hose cool.
When refilling, held expansion vessel high out of cradle to try to remove air.
Any suggestions for next step ?
