Mk3 Cavalier Owners Club | Vauxhall Cavalier Dot Com

They are the same engine and yes if you strip the carlton engine mounts etc off and fit FWD parts then it will go into a cavalier. There will be a spigot bearing in the end of the crank to remove and the Injection loom is a different length. I've done this the other way around and taken a C20NE fro...

Hey guys,

Feel kinda silly asking but want to be sure!

I have found a low mileage late plate Carlton with the C20ne in it but obviously the carlton mounts in line rather than the transverse in the cavalier

With the cav mounts could it be turned and fitted easily or is this a no go area.

So far: New temp gauage sensor New Coolant temp sensor New Spark plugs although 2 very difficult to put back in and threads need investigation / clearing I believe Replaced Distributer cap Checked all fuel lines Checked vacuum lines To be done: Lambda sensor Fuel filter (under car one) HT lead repl...

Rechecked paperclip test with engine running and no fault codes bar 12 diagnostic start and end.

Still can't find any leaks!

As I'm at work until mid afternoon I have removed battery + terminal to see if it's a ecu issue and let it reset itself

Coolant temp sensor already done and made things worse, new lambda going on mid week and if that doesn't improve things it'll get scrapped.

Even with the boot system I still got 350 from a full tank.

Sick of spending out on it tbh, owes me too much money.

Pinched from Steve on Migweb, sure he'll be cool sharing info though.. All you need to know about sensors COOLANT SENSOR . Usually located on the cylinder head or intake manifold, this sensor is used to monitor the temperature of the engine’s coolant. Its resistance changes in proportion to coolant ...

Some details on Crank shaft sensor

http://www.topbuzz.co.uk/info/crankshaf ... sensor.htm

Does state it should illuminate the Ecu light on the dash which did happen before but goes off as car starts each time so I dunno, at £15 though its worth a try I guess.

I think the crank sensor is one of those things that when it goes wrong, the engine doesn't run. Never heard of one to cause fueling issues, but I have been known to be wrong! Did a google search and apparently its one of the main sensors needed to regulate the Ecu and injection system, wish I had ...

Just ordered from VCP

90451441N Vauxhall crank speed sensor
9152245N Outside temp sensor

All for £23.00 which I thought was reasonable, just hopes it helps to sort the issues out

Ok just remembered to do Paperclip test, bit late for some parts but got the following after the diagnostic flashes ***-* (31) Looking this up on topbuzz it relates to NO rpm signal from Crankshaft Position Sensor I believe, could this be the cause of the huge over-fuelling issues?? Any further help...

Didn't mention it

Another job for wednesday night while up in the air!!

135 miles to near half a tank? Dude, at full whack, even the V6 would struggle to beat that.. You must either have a leak somewhere or the gauge is drunk... Guage is ok mate, now that as when I filled it last time it took what I expected about 57 litres as was near empty, no sign of a leak anywhere...

Righty ho.....lol..... I ducking hate this car or it hates me one or the other!! So far changed both the coolant sensors, dizzy, plugs and leads and guess what..........The fuel economy is getting worse!! 135 miles to near half a tank!! FFS Do however now have the new shiny Bosch Lambda sensor in my...

Fuel consumption would probably be better than it is now

Thanks but no thanks mate, lovely motor but omg has it caused some grief

There really ain't much else to check then. Hopefully the replacement lambda will cure it. Yup, cure or kill basically..... Tbh at 135,00 with 40k of those with my disability of a lead right foot it probably needs some internal works, still pulls well however and haven't had the timing checked yet ...

Yup, I'm around for sure that day.....

Keep reminding John as he should be coming along

Which sensor did you replace? Did you check to see if your plugs are fouled from over-fueling? Both gauge one and the CTS on the rear of the thermostat housing, cleaned AFM and filters checked also. Not removing the plugs until I can get down to Chichester due to problems with it previously the plu...

Still no further joy in getting the mpg back to normality so over the weekend I changed the CTS (coolant temp sensor) and took the car for a good run, unfortunately this doesn't seem to have helped and infact it has chewed from completely full to 3/4 tank in just 75 miles :cry: where as I am used to...

See what happens, costing me an arm and a leg but come a nice day and some proper wax and it'll all seem worth it again rather than the monsoon we're not enjoying today!! Yeah, it's this time of year, everybody gets a bit down I think. As you say, come summer it will all seem worth it. Definitely J...

Despite everyone telling me that the previous temp sensor I fitted the single pin type by the thermostat was for the gauge only the car isn't stinking quite so much, yesterday it stank prior to changing the sensor and the main fuel smell was exiting the exhaust along with being a tad smokey on start...

AFM? Air Flow meter? If that is faulty, I'm sure it would throw up a code, at the very least clean it with special cleaner spray, I have a can here, they're cheap enough to buy and handy to keep, I'd do the temperature sender unit first and eliminate that. Just picked it up but tooooo bloody cold a...

That does look a bit crusty, was it definitely that one that the technician mentioned? What about the one on the back of the thermostat housing? The one in the photo is only for the gauge, I think the other one with the 2-pin plug actually talks to the ECU. Yep only found this out yesterday lunchti...

Yup, try £40 for the one on mine!!

Good work Dave, will be dropping mine off shortly with all the spare bits you have

Still having fuel issues!! In fact the last full tank did 270 miles and ate quarter of a tank just doing a local trip without my foot on the loud pedal!! Working on experience and a quick look by a Vauxhall technician who was hanging around on his break and interested in the Cav he looked her over f...

Nasty ain't they, mine was the same even after heat and lots of Plus gas to try and loosen things up.. Unfortunately due to their location the easiest way is to swap out the entire unit that the Thermostat mates to, it does mean a timing belt change and waterpump with tensioner to do it properly and...
