Omega General Help / Re: Removing air con system
« on: 28 May 2022, 11:57:18 »
Possibly, but they didn't build the face-lift without AC, even Plod, and that includes the last 3.0/2.5 :)


Someone needs to go back in time and tell Vauxhall/Haynes that then - would've saved them the bother of doing those electrical layouts ...  ;D

You miss the point, the 3.2s ALL left the factory with AC and front fans and even if AC is switched off, the front fans still run if the coolant temp demands it.

Deleting the entire ac set up will potentially cook the engine as the residual heat in a 3.2 on a hot day will cook burgers.


Ahh, did they change the cooling design on the 3.2 vs the 3.0 because of that then?

Is there a different bracket for the PAS pump or should I just take the grinder to the old one?

(I think they share the bracket but it's been months since I unmantled it...)


I haven't got as far as looking at that bracket yet on my engine, so if you get there first let me know  :y  It looks like it's a shared bracket...

Joking aside, the front fans are integral to cooling the engine, as are the relays.  ;)


The one behind the radiator, yes - but the two in front aren't used on a non-AC car (on the right below). It does away with one of the radiator temp sensors, and the chained relays for the aircon fans.

It's a 6PK1900 belt if you delete the aircon compressor.


Then also a bunch of relays, two fans and half a mile of pipework if you're feeling keen.  :y

Well, it's not really a car - it's more just a car shaped ornament - when you get to that end of the market.


You see them everywhere - thousands spent on 'nut & bolt' restorations, with panels & paint more perfect than they left the production line, a grand spent in the blink of an eye for the exact right original ashtray, engine polished and tuned to buggery, then kept in a cocoon and never driven for fear of it getting dirty or devalued. I find them tediously dull...  ::)

Have you tried 90466214, sure that's the one listed for the x30


Aha, that code throws up a few more suspects from across the GM group  :y  Funny how the supplier engraves one code, but the book lists something else - probably copied down wrong off a smudged fax or something twenty years ago!


Turns out I've also got one under the bonnet of my 9-5 Aero...  ;)

83
It should be the same as the front one if that helps you any ;)


Well, knowing it's there is tantalising but unfortunately it's not spare.  ;D


I'll cap off that line to the plenum valve for the moment and see if that was all of it and silence returns, or discover I'm still chasing another leak...

Omega General Help / Vacuum valve alternative part numbers?
« on: 03 May 2022, 23:35:13 »
I've an X30XE running standalone that's currently making more hissy noises than I'd expect (or remember from when it was in the car). My hearing's dodgy on the best of days, but I could at least tell there was a rush of air at the back of the 2-4-6 bank, as a starter for ten.


It seems that at some point the vacuum valve for the plenum multiram got a teensy-weensy bit bashed and has sprung a leak. The engraved part number seems to be 90466244, but I'm not coming up with much for that. Is there a different number I can search for, or a magic combination of keywords? Or if you happen to have a link to one I can just order, that'd be great too...  :y

The speedo & tacho just went bad in the 2.6 I picked up last year, whilst the rest of the gauges kept going. Thought it might've been a duff battery causing them to randomly just stop, but alas seemingly not. Swapped out the cluster a week later for one from a chap breaking an estate of the same vintage, and not only did I get a working speedo again, I magically "lost" 138,000 miles ...  ;D

Yeah, it's relatively easy to get a bare set of clocks up and running on a bench. You don't need the rest of the loom that you can see in this pic, that just happened to be there whilst I was thinning it out  :y  Without a spare connector, I'd just use small crocodile clip leads to put 12V onto pins 19 & 25, and earth to 7 & 26.





I don't recall seeing anything that the pinouts on the connectors were different for V6 clocks to any others, but just be wary. You can easily trace the live and earths round on the back of the unit anyway;

If you've doubts about the fuel pump, could you not loosen off the fuel line going into 1,3,5 and then jumper the pink pump relay (in the engine bay) ... ?

Omega General Help / Re: Lack of heating - pfl 3.0 MV6
« on: 17 October 2021, 22:38:04 »
Had a similar experience with mine recently, and it was down to the "Matrix Air Temperature Control Arm" having become disconnected on the driver's side. This drives another servo that opens/closes a valve on the heater matrix, without which the hot water from the engine just comes in and goes straight back out. As per maintenance guide -

Action shot of the arm for you - thought I might as well film it given I was already upside down in the foot well...  ;D

Omega General Help / Re: Autobox gaskets?
« on: 15 October 2021, 12:57:11 »
Interesting thread deviation whilst I've been away all week with work.  :)  This 2.6 auto just happens to be what I ended up with at the time, but the reality is it's a high-mileage relic that doesn't justify any efforts at improvement over standard, but should soldier on quite happily with regular maintenance.


New gaskets and a rinsed out filter it is then...  :y

I wasn't ta, but hadn't got much further into thinking the job through than pricing up the bits as yet - mostly to see if it just stayed on "the list" and I did something else instead  ;)


That's why threads like these are great for flushing out little tidbits of knowledge  :y
