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
