Due to an utter moron in a tractor going down a flooded road at 35 to 40mph my Z4 got covered in muddy water. I've cleaned most of the car up, which has meant things like taking the wing mirrors apart to get full movement back, taking the door to bits, etc. However the engine is still getting way too hot - it's struggling to keep the oil temps under 130C under any kind of non-cruising condition. There's no mud on the front of the radiator or IC anymore so I'm assuming that it's coated with dry mud on the inside of the fins.
Are the radiator & IC up to being directly pressure washed or is this a steam cleaner job?
