Hi. Any advice as to cause of overheating on my V5 Passat? It comes up to normal temp after about 5 minutes, stays there until about 25 minutes, and starts to climb into the red. However, putting the heater on high keeps the temperature down.

After running for about 50 minutes today, the bottom radiator hose was cold, and the top hose hot.

Is this a symptom of a blocked radiator, or stuck thermostat?

Advice, as always, is appreciated .
