I am soon going on a long drive down to S W France, probably around 2,000 + miles. I get the MV6 serviced regularly. Very recently had new coil packs. I sometime read here about crank sensors failing. Just how frequent is this ? Should I get it replaced before going ? Are they expensive ?

[minifreek]

Crank sensor is usually just a problem limited to the 2.6/3.2 engines.... not normally a problem on the 2.5/3.0 engines...

It wouldn't harm to get it replaced, if you feel it might need it - just in case, but hen Id be inclined to replace evry sensor too....

Just make sure you have Euro cover with the RAC/AA/Greenflag.....

..... Just how frequent is this ?

Not very, but having a spare when in Deepest France could very well save you a day or so of waiting for a new one. French only really do French cars. Many years (15 ?) ago, my V6's exhaust failed very noisily, I calledinto a Feuvert ... a French Halfords .... and they wanted €700 for cheap Bosal exhaust

Should I get it replaced before going ?

No, just put a genuine spare in the boot, just incase.

Are they expensive ?

Cheap, pattern sensors are very cheap, but IIRC my OE from Vauxhall was more like £70 (I think)

And failing crank sensors does affect 2.5/3.0 as much as the later cars

[Bojan]

I believe you have, but worht a mention:
Check plug wells for oil (leaking camcover seals) -> IMO long trip could ruin HT leads which are deteorated by oil, but were still working perfectly fine before the trip.

Also, check your scuttle for leaks -> if it leaks, on heavy rain, quite a lot of water drips all over the DIS pack. Hot DIS pack and cold water is not a good combo.

One more thing -> HBV - they fail sometimes, spraying cooland around the back of the engine. Again, DIS pack.

Helpful. Thanks 

But I may just get it replaced and keep the existing one as a spare. I read here that they can fail after 100k miles. As far as I know mine has never been replaced and I'm at 115k. I did much the same trip last year without any problems, but I'm a pessimist

I carry a spare new crank sensor in the boot all the time, takes up very little room, and is actually very easy to change.

Most things that fail on the Omega are "bodgeable" to a certain extent, or pattern parts can be used to get you home.. but a failed CS means the engine stops and will not run.... end of story.... and getting hold of a GENUINE GM spare may be somewhat difficult, especially in France.

Exactly my thoughts. I'm getting it changed before going and hanging on to the old one as a spare. I've had a sensor fail on a previous Omega. Yes' it just stops 

It may be easy to change for car DIY-ers, but I simply have no idea about even where this is or where to begin. I do none of my own work. So my local independant garage is doing it next week, with genuine Bosch part.

[Mr Gav]

If you`re driving to France no doubt you will have some form of breakdown cover, so as long as you have the part in the boot then they will be able to fit it for you at the roadside

Entirely your choice obviously, but I'd go with a genuine spare in the boot. The reason being, one of my crank sensors lasted over 60k miles and another lasted less than 20k miles. They were both genuine, purchased over the counter at my local Vauxhall dealer.
Another reason to take a spare in the boot is that, if you believe the one on there to be original, the garage will just cut it off, as the original is wedged behind pipes. I've tried to remove them intact but the heat shield around the cable is wedged between the pipe and the engine block, making it nigh on impossible to remove without damage. A garage won't mess about, they'll snip it, yank it out and fit the new one, leaving you with no spare. 
Be handy if someone close to you could show you where it is to make it easier for you in the event that you need to change it.

You might want to check that with TheBoy.

All V6s are prone to crank sensor failure.

Well, I think so. My mechanic said that Bosch is manufacturers part, and this seems to

But, if anyone thinks differently . . . .

You cannot remove all of a original crank sensor.

[terry paget]

Changing it involves getting under the car. I suppose I might manage to raise the n/s front wheel high enough with the car jack to get the spare wheel under it, then crawl under the car. Is that the recommended technique?
