Just in case anyone is interested, I put together a simple pictorial howto on
how I changed a fuel injector on my MY03 XC70 with 108K . I did this howto
because I was not able to find any other procedure like this documented.
So here is a little insight to my problem and how I solved it. I was idling on a
fairly hot day about 90F – 32C and suddenly the engine started to run rough.
Engine light came on. I went down to AutoZone and had them pull the codes
(for free).
PO301 (misfire cylinder 1)
PO201 (Injector cylinder 1)
So my first thought was to replace the all 5 spark plugs and the coil pack
($62.00USD) on cylinder one, which I did. It ran better then before, but after
about 15 to 20 minutes running, the engine would start to shudder again. So
back to AutoZone and pulled the codes again. This time it was just PO201.
Apparently I had two issues, coil pack and plugs solved one, and the injector
was still a problem. So after trolling EBay I was able to buy a new Bosch fuel
injector for $25.00USD.So this is what I did to replace the faulty fuel injector.
- The first step was to remove the plastic cover. I had to remove the bolt on
the intercooler tube to gain access to the bolt (right side) holding the plastic
fuel injector rail cover.
- Next step was to remove the two bolts holding on the fuel rail.
- At this point you will have to remove all the metal retaining clips on all 5
fuel injectors. Once the clips are removed, unplug all the connectors from
the fuel injectors. Then you’ll need to press the 2 tabs in on the plastic fuel
line retainer, located underneath the fuel rail (between injector 1 and 2.)
Once the tabs are pushed in you will be able to pry the rail and injectors
from the cylinder head. This part I did very carefully with a long screw driver
evenly prying the rail, from each end.

Clips and connectors removed
- Once the fuel rail was removed, I removed the retaining bracket, which kept the fuel injectors and fuel line retainer in place. Once removed, the fuel
injector(s) can be pulled out.
Note the crack on the old fuel injector
- New injector(s) installed. Injector rail retaining bracket reinstalled, put
everything back in, and bolted up and presto you’re done. This whole project
took me around 45 minutes from start to finish. Problem solved! Just an
added note, it never hurts to throw a little fuel injector cleaner in the gas
tank. With all the ethanol in the fuel today, things can get clogged. Now
my XC70 pulls like it was new again.
Cheers.
Oh and this is my first post here, so "hey" to everyone!
