2003 Buick Century Question: Can the spakplugs be changed while the car is on the ground?
Yes you can reach them. The O2 sensor gets in the way when doing the rear plugs so be carfule not to damage it. - gmc4me
false use a sparkplug socket,5/8ths deep dish would work too. all plugs can be done easily from ground. id be willing to change them for you for a small fee? - kevinnoah
