hi everyone, just wondering, i changed my spark plugs a while back on my 2006 V70 2.5T, but i wanted to know if you also have to change out the coil packs too? or do you just change them when they stop working? thanks

You shouldn't have to unless you have a misfire or something.

 

Don't have to change them until they malfunction, rare. Keep in mind they are quite expensive. I was quoted close to $400/ea., and they would have to be ordered from Volvo. Good luck.

 

thanks for the info guys...

$400 x 5 = $2000!!!!!. That's more expensive than a new coil, distributor and wires on a small block Chevy in the good ol' days! For that money, I could replace all those parts, the intake manifold and put a new Holley carb on one! I guess I better bring in the whole neurosurgery team the next time I replace plugs so I don't damage any of the coil packs.

 

you must be talking about $400 to do the whole job at the dealership, I have replaced coil packs in my 960 and the coil pack cost me around $55 and we just replace all 5 in my friends c70 for $ 280 which is $56 each, so the pack are not that expensive and are very easy to install....but to answer you question NO they only need to be replace if a particular cylinder is misfiring!
