Changing front lambda sensor 2.3 t5

[Green440wedge]

I would appreciate some experienced advice -

I am going to replace the front lambda sensor following the occasional fault code and odd running.

Is this done from below on the 2.3 t5? Mine is a P2 V70. It looks hard from above, and would need the heat shield removing which I don't fancy.

I don't have a 22mm spanner which gives enough clearance from below. I am going to get a Halfords oxygen sensor socket. Any views?

Cheers

Hello Green440wedge.

It's a while ago since I changed the sensor, but from what you're saying I think you're along the right lines. Volvo have a special tool for the job, I didn't have access to this or a O2 sensor specific tool so I bought a cheap spanner, cut the shaft down and ground the end smooth.

I seem to remember there is a topic on this forum with more information, maybe have a search around, I don't remember if it was T5 specific but it may shed further light for you.

i did the 2.4 t5 from above I think, cant remember but if it is from above you need to remove the heatsheild on the exhaust manifold first

I read the warnings about buying "universals" or cheaper sensors as the Volvo system was sensitive so I went with a DENSO model as the name, along with Volvo's, was on my original.

The non-turbo was easily reached from above as only the foil heat pipe needed to be removed.

As far as tool goes, don't get the huge, clunky, tall socket as it is really massive. If you must buy something specific, get something thinner. Also, should the available tools seem wrong, consider cutting or even bending a regular wrench of the proper size.

Of the 6 of these I've done, none were tight at all.
