ouch, keep the hood closed. Only open it for checking fluids. This goes for your F-1-fiddy also !!!

 

Pressure wash my 03 Expy and 09 Fitty once a year, 1200psi. I go back and hit it with an air gun. So far, no issues.

I don't do it on my 91 Z nor my 66 Stang, however.

 

Sprayed down the engine bay on my 2001 V10 superduty when I was getting it cleaned up to sell. Started up but idled very rough and was definitely missing lots of power and running very bad. Let it sit for over a week to dry out but it never helped. Ended up getting water down in all the coil packs and it was causing all kinds of random firings with the ignitions.....$700 later I learned that fords are notorious for this.

 

Not just Ford.

 

That sucks a DA is a must have.

 

I'll buy one and tell her that I agree it's a must have. After I'm done with her car she will realize.

 

Got a call from the dealer. They were able to get the car started but it runs like crap. They found that the 3 back ignition coils shorted out. The mechanic already took apart the intake and cleaned it. He put it together only to find out the coils have shorted. They are charging me for the coils and not the labor because he missed it the first time. However they have to charge me for the initial attempt to fix the problem. This quickly turned from an $400 bill to an $750 bill plus tax. I can't believe I caused that much damage. F*&k!!

 

A lot of cars can have the engines washed when new. Unfortunately, as they age, the rubber seals that keep water out of places that it should not get into start to harden and crack. This lets the water in and causes problems. Since its impossible to know when to stop washing the engine, I usually just leave them dirty.

 

Sorry to hear that man. Like I said in an earlier post though, it's not an uncommon problem these days. And yet there are those (and you heard from one) who seem to get away with it. After having spent some money to fix the same issue a few years ago, I don't stick my head in the lion's mouth anymore. And I absolutely refuse to detail engine bays on cars I detail for customers. Just not worth it.

 

Good point! Even though my truck is new I think I'll stop washing the engine bay. Now that it's clean it should be easy to manage with wiping it down every once in a while.
