hey virused, you said dont do it while car is hot and not to overtighten, i did both.. whats that mean for my truck =/

 

i think he said it so you dont
a) burn yourself
b) work on the hot engine cause moetal expands when heated up... so if you take a 'hot' spark plug and put in a 'cold' spark plug... u may cross thread the heads on your engine.... not sure

 

i said it because when you are working on a hot block, you can easily strip the threads inside of the block because the metal is softer. also, i have seen people crack aluminum block by overtightening when it is hot. never overtighten or work on the block while it is hot. rule #1.

 

30,000 Miles (48 000 km) or at 24 months
â€* Change engine oil.
â€* Replace engine oil filter.
â€* Replace engine air cleaner element.
â€* Replace spark plugs.
â€* Drain and refill automatic transmission fluid
and change filter (4.7L only).

 

NICE!! whats the minimum downtime youd give it to cool down?

 

The 4.7s don't have aluminum heads, do they?

 

thakota: let it cool down until it is at ambient outside temp. dont rush it, go get a 6 pack and tell some stories with your friends. depending on outside temp and engine temp when shut off, it usually takes between 1 1/2-3 hours to cool all the way down. so crack a cold one and chill out!

horatio, that is a great question, and i dont know off of the top of my head. i would assume they are aluminum, but i am really not sure. i will check it out when i get home.
