what is that noise on my 1988 Ford F150 I-6 after i turn it off. it sounds like some kind of fan. but when i open the hood nothing is moving. it doesn't bother me but i've heard up to like 20-30 mins after i shut the truck off. none of my other ford products do this. and i am curious if this is going to run down my better

 

Could be an after blower have same thing on my truck, think its called an after blower dont hold me to it.

 

ok since we basically have the exact same truck except mines a year newer

 

you have a fan to cool the fuel injection system.

 

On the passengerside plastic wheel well housing is a small fan enclosed in a black metal housing. It's used to cool off the fuel injectors/fuel rail after you shut the engine off. The fan only comes when a certain temp. is reached and when the engine is shut off..

 

ok thanks guys i thought i was an idiot i knew i heard something.... ok welll i let the ford do its job then

 

and what is this coffee can looking thing by the battery is that normal or something somebody tried to rig up

 

that is the vacuum canister.

if you do not have one, go out and get a manual.

it will help you for many years.

 

That is the emissions vacuum reservoir.

 

Ahh yes the good ol Coffee Can, yeah my brother always makes fun of that on our truck. It really does look just like a rusty old coffee can someone cobbed up in there to do something. It has something to do with the emissions, I think its some kind of carbon filter or something. Definatly dont quote me on that one though, but its definatly supposed to be there.

 

Thanks guys you have to forgive as the truck is older than i am its an 88 and i wasnt born until may of 89. and my first 2 trucks came from the dark sides. (86 Chevy, 92 Dodge) and i just thought it was weird. but i did find that even though i liked the chevy and dodge. they just cannot compare to this damn ford... now i know why everybody's always so crazy about them ford trucks
