Every spring season, the pollen becomes a nuisance to the city I live in. I just opened the hood of my truck and it is filthy. I want it to look new again.
My question is, is it okay to high pressure wash the engine under the hood? I used to drive a Celica with a Cold Air Intake and I ended up hydrolocking the engine which concerns me about spraying the dirt off the engine with high pressure water. I would like to clean the outside of my engine really soon but thought I should ask if anything under the hood can get damage from the high pressure washer. Thanks.
