Omega B 2,0 l, 1 36 HP , Caravan, Built 98 I went on holiday with Omi , first 1500 km, with the caravan at the rear, no problems. Cooling water temperature about 96 degrees In Austria, Gerlitzen – Bergstraße: It goes on, without caravans!, Cooling water temperature gets into the red area , Blowing / steam, the ride uphill is over! Return trip: 1500 km, no problems. Because Omi did not like the mountains, I had changed the cooling water pump before. The old pump had no damage. Fan runs impeccable. No coolant loss, the hoses are filled and hot. Cooler is not dirty. Cooling water I had also changed. It is clean. What can I do to prevent Omi from dying of heat death??? Cereale
