^^You all are describing same problem my van is experiencing for a really long time now and I can tell you it is directly related to your A/C being on. The radiator is not cooling efficiently enough to compensate for added heat from a/c condenser fan. On a hot day at idle with A/C off temp would remain stable. But with A/C on it goes up in five minutes. It will cool great while in motion. Last week I had fan clutch serviced with silicone oil because I read this thread and tried static advice, but the problem is still there. Mechanic advised to do radiator flush or seek new rad. Hope this helps.
