Hi I have a 2003 Mini Cooper s. The water pump went and it over heated once. I replace water pump, all hoses, and thermostat. Everything was fine but the coolant started to leak at upper radiator hose neck so I go a new radiator and replaced it. A week later started to leak at same spot. I’m lost, seems like to much pressure and has a miss when starting up til warm. Oil is clean no mixing. Anyone have any ideas
thanks
