Problem with my car after washing it.

I'm experiencing a problem with my car after i washed it yesterday. While breaking i hear a very smooth "scraping" sound. It sounds like its coming from the left front, and sounds similar to a tire scraping the chasis ever so slightly, or maybe a breakpad rubbing against something.

 

During washing i used soap on the entire body, including all 4 rims and windows. I used a wash mit to clean the rims and i followed by hosing down each rim thoroughly. Also while washing the windsheilds lots of water dripped down to the wiper area.

 

Could my cleaning approach of caused this funny noise? What do you think is wrong?

probably just rust buildup on the rotors -- one or two heavy braking sessions should have taken care of it.

 

that'd be my guess at least.

hmm...same thing happens to mine after washing it because the brake disc get a thin layer of rust on them..but that only lasts for 2 seconds, once I brake all the rust gets scraped away...same thing happens when I park out in the rain.

 

If the sound is still there longer than that I would pull the wheel and take a look.

I always wash & wipe dry the rotor...the "Rust film" is what you are experiencing;)

yes but the problem is still there today after i drove 30miles to get to work

City driving or highway?

Did you get water in the intercooler?

Oh noooooo....if you did.....

he also admitted that he used soap -- can you imagine if he got water AND soap on his intercooler.. i'm surprised he was even able to make it out of his driveway..

Bastards

Did you get water in the intercooler?

Yeah, I thought maybe you had forgotten to mask off your hood scoop to prevent water and soap from getting in teh intracooler!

 

Thanks god its only the rusty rotors, whew...

 

 

 

 

 

 

 

 

 

My rotors don't rust anymore. I had the dealer put on stainless steel rotors.

Water "IN" the intercooler? Please explain...

^^

 

oh no...

Water "IN" the intercooler? Please explain...

 

on the intercooler is more of a problem than in it --- if water gets in it - usually it's hot enough to turn to steam right away and just pass through the engine..

 

water ON the intercooler -- thats trouble..... you get the aluminum heating up and shrinking and expanding at the same time leading to major problems - least of which is the engien seizing and the intercooler MELTING!

But if it melts completely then it's been proven (where's that old thread?) that a regular, house-hold mop can soak up the liquid metal pooling at the bottom of the engine bay quickly and efficiently.

I hear the same thing on my car, I'm going to bring it to the dealer to see what's up with it. It just happened recently and it still brakes ok...

So... if your engine is cool there is no problem with detailing etc. correct.

as long as you're really really carefull and dry the intercooler immediately afterwords -- for whatever reason, the alloy used in the oxidizes really quickly - leading to corrosion.

 

you also need to be carefull because the hood scoop opening provides a path for water to get into the rest of the engine bay -- you dont want water on all those other components -- especially all of the wiring.

 

 

 

 

one of the members on here developed a hood scoop plug to avoid the possibility of water and/or soap of getting into the engine bay and onto the intercooler. Looks like it would work well, however i use the cheaper aproach of stuffing towels and plastic bags into the hole to block it.

Isn't this the same issue addressed in SOA Service Bulletin #8675309? Have we determined whether the VIN ends in an even or odd number?

 

Whatever you do, do not attempt to dry the intercooler yourself; if the dealer detects tampering, it could void the warranty. Not even the Magneson-Moss Act will save you then.

 

If the dealer feigns ignorance, print out a copy of this thread from legacygt.com and show it to the Service Manager.

I had the same problem with my brake rotors rusting. My first attempt at solving it involved painting the rotors with high temp paint, the the damn pads kept scraping it off. Not very pretty. My last solution involved putting grease on the disks. Problem solved. My disks haven't rusted after 5 whole months of sitting in the wrecking yard! I must say that I am a GENIUS.
