Hi,

Went driving along a very dusty road. Have cleaned the exterior but would like to clean the engine compartment. Before I spray the engine compartment with water, is there a need to cover any part of the engine?

I, for one, I pressure washed the engine without any precautions.
But I have a TD4 engine, not a gasoline one...

Most of the Freelander 2/ LR2's engine bay is covered in removable plastic pieces. I simply pull off the engine cover, air filter box, battery cover etc... one by one then take them inside and clean them in the laundry sink. Any pieces that are too hard to remove are lightly sprayed (hosed) and wiped with cloth.
Finally, I wipe (with a damp cloth) the insulation under the hood (bonnet).

No need to cover anything. All the electrics are well protected. I do mine once every year and have done for 6 years. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........
