I have a really dirty engine bay and want some advice on the best way to clean it!

I don't want to damage the paint.

The reason I ask is I have oosed out the engine bay before and got corrosion on all my terminals.

Do you use degreaser in a can and then wipe it off?

First cover your battery terminals, cam cover +/ coilpacks, afm, alarm/siren.

Use engine degreaser, spray on hose off.

Use a cloth dry out as much as possible, then uncover the covered bits, and start the car up in as short a time as practical as to dry out the rest.

Then continue to detail the rest by hand using metal polishes and/or silicone spray.

On the inner panels - I use cut and polish, in a similar way i'd do the exterior panels.

i do as what howie said.. but i have som slight changes:

- cover alternator, battery, alarm, coil packs, AFM - try uising plastic bags and/or old t-shirts or rags

- spray with a little bit of water

- use about 1-2cans of degreaser.. spray it all over everything and leave it do its job for about 10-15mins

- hose it all clean

- get some WD-40 and go nuts over all the electrical items you can see - electrical plugs, wires.. i sprayed WD-40 over the entire engine bay basically!

- remove the covered items such as alternator etc.

- start the car and let it idle for about 5 minutes with the hood open.. then take it for a brief drive

enjoy!

cheers,

Warren

get a heap of cans of the cheap export degreaser. use a few cans to get it to soak into all the crap, then use the next few cans to work like a pressure gun. get in as close as you can so the pressure sprays off al the crap. or go out and buy some of that real expensive stuff that you have to mix up. that stuff will lift off some seriously stubborn gunk.

Or you could do what im doing and completely remove the engine and every little nut bolt and washer and polish everything one by one...But i probably wouldnt advise this as it tends to take just a little longer :( Mind you the end result should be insane!

cover all electricals... then give it a fine spray of this stuff called "shift it" which you can get from most auto shops like homobarn and crapco. Make sure you don't get it on your paint as it sorta eats into clearcoats. leave it on there for a couple of minutes then douse the f**ker with a highpressure water hose. make sure you wash off excess etc.

goes from filthy to clean in minutes.

I've never been as carefull as you guys in my almost 5yrs and almost 150,000km's of owner ship.

I head down to the local car lovers/bp self wash, pop the bonnet while its still hot, shove a dollar in and spray the engine bay with its degreaser. I then wait a few minutes, and high pressure spray it all off.

I'm not carefull where I don't spray but I don't concentrate it on plugs etc.. I simply just spray it off.

Never had an issue except for when my injector plug boots were cracked, they soon got replaced. :D

Ours in Adelaide do.

Its called Engine Degreaser/Tyre Cleaner.

To wash the car I never use their brush. I always bring my bucket and mit along with my own car wash. I then only use the high pressure wash to wash the suds off. :)

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
