How do you change the spark plugs in a 2001 Tahoe?
with a socket. the spark plugs should all be into the head making it alot easier to change. it should take less than a hour and replacing the wires would be a good idea. be sure to replace each wire and plug one at a time so you dont lose the firing order..this would be bad. just start with one wire and plug then put it back together and then go to the next wire and plug. be sure to replace it with the same plug. they have platnium tip spark plugs and are good for 100,000 miles. i would suggest going right to the chevy/ gmc dealer and buying it from them. be prepaired, these spark plugs are not cheap should run $7.00 TO $10.00 A PIECE!!
