The engine is a 116 FI (29 B4204T3) <-- don't really know what that means... I want to put in a K&N air filter to save cost in the long run by being able to clean it myself, and also to increase performance on my '02 S40 1.9L. When I search, I find two different types, the flat and the conical. ...

Can anyone help me with the instructions on how to change the spark plugs on a 2002 S40 1.9L? I really don't have a ton of money and would like to do them myself if it's possible without a torque gun or something like that. Thanks~

The code was P0128 when I got it checked.

2002 S40 (1.9L 4cyl Turbo 5A) that has had trouble starting. It is turning and sometimes won't go all the way, while other times it will start right up depending on if the car has been sitting or driven. The check engine light came on that indicated the coolant temperature sensor. A mechanic told me...

This one has been solved! In my ineptitude, I mistook the motor and bracket for the transmission and bracket. This is not an obvious mistake, so I had a laugh and got my head straight again.

I have a newly acquired 2002 S40 (1.9L 4cyl Turbo 5A), and there was a time when the horn worked periodically at best, but now it does not work at all. The fuse is fine, but I don't know if an electrical malfunction could make this happen. How do I test for this? If it is in fact the horn itself, ca...

Thank you for the confidence booster. Well, I believe I found the problem. The bracket only had three of the four screws showing, and when I felt below where the bracket was connected to the motor, the missing screw wasn't just absent, but that quarter portion of the bracket was broken off and missi...

I made sure that it wasn't the wiper itself that had a loose nut or malfunctioned because of stripped splines. The whole unit moves actually. Could it be something if the bar that seems to connect the two wipers moves when you jiggle the drivers wiper? I dissected the whole thing to get to tighten t...

I am investing in a newly acquired 2002 S40 (1.9L 4cyl Turbo 5A) that is in rather good condition and 95,000 miles. This is the first fairly used car I've purchased like this, and want to take the necessary measures to sustain and prolong its performance. The windshield wiper (driver side) is loose ...
