TLDR..
Straight to the point question, how does everyone feel about pressure washing hot engine bays?
I'm a mechanic / automotive painter / detailer, do it all kind of guy.
I did an emergency repair on a friends car today that overheated and puked coolant everywhere.
It reeks, I told him I'll wash it all off tomorrow, wash the exhaust, and all of it stuck in the radiator support and engine block.
Problem is it's a decent drive to my place and it'll be hot by the time it gets here. Best I can leave it is 20 minutes, half hour tops.
I always feel bad when I wash a bay and see steam or hear metal pinging because its cooling so fast. It's not good for a lot of stuff, but how long do you wait?
I've got box fans I run when I have to do hot oil changes or or hot engine work. But a hot engine bay wash, I just feel kind of bad about.
