How to change spark plugs on your Volvo V40 & S40:

It’s very simple, actually, to change your S40 & V40 spark plugs; and, yes, it’s worth the savings. Make sure you buy genuine Volvo plugs or what’s recommended in your owner’s manual. You must also gap them to the correct specification. The how-to is below. (Tightening torque is 20.5 ft. lbs, which works out to be about the same as tightening them up until they bottom out and then another 1/4 turn).

Here’s a two-minute, 27 second YouTube guide on what you will see when you pop the hood, and what you need to do to get to, remove, and replace your spark plugs:

The Volvo S40 is a series of compact and subcompact executive automobiles marketed and produced by the Swedish manufacturer Volvo Cars from 1995 to 2012.

Spark plugs

Your spark plugs perform an essential role for your engine and should be monitored/maintained regularly. If plugs fail they can cause all sorts of damaging effects to an engine so you shouldn’t cut corners with these.

If nothing else you should look at your plugs at least every year to see what’s going on in the engine the plug can tell you if you are too rich/lean and a multitude of other things pick up any Haynes manual or similar for a description of the various engine conditions shown by your spark plug tips. Anyway, down to business – how to change plugs :

Why use Genuine Volvo Spark Plugs? Let’s be honest, there are times when using an aftermarket part on your Volvo is not only ok to do but very reasonable. Take suspension parts like ball joints, tie rods etc, there are a lot of good companies out there that make decent products and some of the companies like TRW, Mehle and Sachs actually make some of the parts that are sold as genuine Volvo. So why can’t I use NGK or Bosch plugs instead of genuine Volvo spark plugs?
Don’t NGK, Denso and Bosch make some of Volvo’s spark plugs?
