As I've got all the front gubbins out while changing the compressor and condenser, it occurred to me that I could fit my spare crank sensor in place alongside the existing serviceable one, using the umbrella principle that if I have one in place, it will never fail.
Any thoughts?

If you do that Chris, sod`s law your original won`t fail

.. and when it does, the spare will have perished due to the heat of the engine bay.

[chrisgixer]

I wouldn't fit it until needed. Personally.

Just give it a good talking to whilst your down there.

I was working on the idea that the original is designed to cope with the same heat.

It is, but for how long?

[Shackeng]

Ah, are you implying that it is the heat that causes them to fail? I thought that it was just electrickery again.

The wiring runs very close to the exhaust manifold. Its wrapped in a heat shield,which isn't much more than a piece of silver paper.
Over time the heat breaks down the wiring internally until it fails altogether. Hence the advice to route it differently when replacing.

Wouldn`t it be prudent to use something like this when fitting a replacement then

Unless the new sensor is faulty, any v engine owner will only need to fit one sensor per cars life. As said, once the sensor is re routed, it sits in a considerably cooler environment.

[Shackeng]

OK, so how about I fit the spare in place but using the new recommended routeing? Then if it fails while I am traveling away or abroad, which is when I use the 3.2 the most, it will just need connecting at each end.

Its not routing it that's awkward though. At roadside, you still need to jack the car, get under there lieing on the ground to unbolt the sensors end, fit the new one, and bolt it back in. The rest, that your proposing is a two minute easy job by comparison. Your also introducing the possibility of debris, rust, corrosion in the plug end. Or possible damage to the sensor end as it will need to be tied up somewhere.

Your sensor, but not worth the risk IMO. But each to their own.

Keep it safe in the box, or there's a chance of two non working sensors when you really need it.

I agree with Chris,I wouldn't fit it till needed as following alternative routing makes it easy to fit anyway

[chrisgixer]

If your considering partially fitting. IMO it would be better to fit it new completely, as the new routing, job jobbed.
