Just bought my son a 1999 Exploder and I want to show him the proper way to spiff up the engine compartment. It's been many years since I have used Gunk. Used to do it all the time on my first car 1972 Cutlass.

Seemed that no matter how well i covered the rotor cap and carb inevitably the fucking thing would not start for a couple of hours.

Anyway what should I not spray in order to look like I know what I am doing and so the damn thing will start when we are done?

Thank you all !

I'll be honest here is what I do on both my 95,04 and 05 jeeps. Go get a gallon of purple power at the parts store and a spray bottle. I fill the spray bottle with straight purple power. Spray the entire engine compartment down. I do not avoid any components. Let sit for 15 minutes however do not let it dry. I always start with a cold engine. After 15 minutes I take the pressure washer to it. Try not to stay in one area to long and work from top. Only thing I avoid directly spraying is the air intake.

When done start it up and let idle for a bit to dry off.

I do this every 6 months or so and never have an issue. One word of advice though is to make sure not to do it on a paved driveway or you will leave stains.

He means don't spray directly into the connectors. Yes, they are moisture resistant, but not idiot proof.



Every once in a while I give 10 bucks to the mexican guy that pressure washes all our equipment to do my truck on his lunch break. He uses degreaser and a pressure washer with a 25 degree tip. He is smart enough to not spray real hard onto the electrical stuff.

Simple green works GREAT.

I've used both Simple Green and Purple Power and either a garden hose with a good nozzle or a low pressure pressure washer. After everything dries thoroughly, I mist the engine compartment down with Armorall or something similar.
