Steam cleaning the engine bay is fairly safe m8.
I cover the induction kit and MAF only.
If I dont cover the induction cone it drives like a dog, so I guessed that was a bad thing.

scooby,dlm.

thanks for that,where would i find the maf sensor?
Is it around the air box?dont have an induction kit on mine.

Thanks again,dave.

not disaggreeing with you japimport, but i heard its a really bad thing to try steam clean a scoob engine, with it being a flat four. thats why ive always left my engines alone in that sence.

anyone clear this up as i would like to give my 95 wrx a clean under there too....

Keep away from the alternator aswell and you should be ok.

Leaving engine running or you could have problems starting after

DONT clean the engine unless you want a nice BIG bill for the alternator
It doesnt matter if you cover it up, water can still get into it and then your looking at a 600+ pound bill for a new computer controlled alternator.
Take my word for it, ive forked out 600 quid for one of these

I gotta be honest i damaged my alternator on my classic and it set me back £130 so i haven't done it since but i does look good when done . Next time i think i'll remove the alternator first.

New age models have a computer chip in them that controls the charging, they are unfortunately non-repairable

I think at the risk of forking out £600 i have to agree with Tony i'd leave my engine bay well and truly alone. Bad enough paying £130 for a bog standard alternator for my classic.
Although a mate of mine does his regular without any problems.

Done mine a couple of times on a blobeye and a classic. Cover the alternator well, the intercooler and fuse box. Don't use a pressure washer just a hose after Gunk or similar engine cleaner.

I see no need to cover the IC.
I have IC spray and I'm sure that makes it wetter than a general steam clean. but so be it

The alloy fins on the intercooler are delicate. Its not te wetness that can damage

take out the bit you want to clean, spend a good nice sunny day, taking it apart (remember how to put it together again!) i think thats the best way
