Omega Electrical and Audio Help / Re: rpm sensor fault

« on: 18 November 2008, 04:03:22 »

My 2 pence worth.

Hmm. I'll check it out and post here... This problem is quite common among Vectras, Monza/Ascona, and Kadett, that uses the (same?) 2.0i engine.

Buuuut... I have a 3.0L and usually these codes say NOTHING... my car was crazy, not starting, dying and the like. I kind of reset my ECU by unplugging battery for a few hours and that cra* ran well after. Error codes I got: 73 plus 13. Lambda + air flow sensor...

HTH.

Omega General Help / Re: starts then cuts out when you press the accelorato

« on: 21 November 2008, 19:27:11 »

I had the same problem. Check out the fuel pump relay and the pump itself. My case was the connectors were loose, so the car started, I could drive for a while, then it "disconnected", the engine would not accelerate  then cut and then ROADSIDE. the car never started.

All i did was to check the pump. It was failing sometimes (was afraid of having to change it), but it all turned to be the relay (you can't see somtimes if it is the guilty, but i suggest you disassemble it, put is again and ask for someone to start the engine while you look at it.

It should start the pump when you turn the key. Another silly test is go under the car and listen if the púmp starts when key is turned (2 pple). Other tests involve tools... and i cant help.

What i did: resolder the realy contacts to the PCB, they were loose, you couldn't see it however. the car is best to this day. drove 100km today, not a single fault, except it wanted to overheat in traffic jam, but didn't. Cost? R$ 30.00 for multmeter (used to see if i got 12vdc at the pump contacts.) Had the solder already at home, so say i put 0.05 of solder plus 0.25 of electricity

Other thing: the temperature sensor sometimes is ok, but it's wiring is rotten ... need to be checked with a voltimeter, should give if not wrong, 5vdc.

if the wire is corroded, no deal.

check a bad video of it: http://www.youtube.com/watch?v=QOrGRd65_1s

HTH!!!

Omega General Help / Re: need a haynes manuel.

« on: 23 November 2008, 15:35:17 »

If you were a REALLY good boy, you'd scan it and send me a copy   .. Just kidding...

I ordered my manuals from www.abebooks.com . I wish they come soon... While many of my doubts are answered on line, it's better to have some printed reference... only for safety

I don't know if it can help you in any way, but learn if the engine is used in other cars. You don't have to have the exact manual for repairing your car. For example, my gearbox is used in about 10 other models (honda, toyota, bmw, suzuki, isuzu) from other makers.

This allows me to get a manual for other car, covering the gearbox, buy cheaper rebuild kits (in USA they are very affordable, send by mail), etc.

Other example: the engine used in the Carlton (brazilian 1993-1998 omega) 2.0 is the same of kadett, ascona/monza, vectra; the 2.2 is the same of the s10 truck; the 4.1 is a tune-up of the opala (opel rekord); and so on.

Ah, yes: we make a lot of adaptions here; sometimes you get the same part from other car. Example: brake valve (the one that goes to brake assisting "pan") at store: omega: R$ 150,00, vw kombi: R$ 10,00 (R$ 1,00 = US$ 2,40). works and fit equally. I suspect it's the same part. This includes brake pads, anything. If you ask for "omega" the atendant will poke you in the eye (and you sometimes can see written in the part box "Fits: car 1, car 2, vw beetle, gm omega"... if you ask for the beetle part, it's a 1/10 ou 1/100 of the price...  

If you want some omega a/b material (unfortunatedly, looks like there is no manual for omega diesel, so learn which other cars have the same engine and look for them), i have some 500MB of it. while i hate to have this stuff instead of an original printed book, it's better than nothing.  :-/ :-/ :-/

Omega General Help / Re: Front wheel bearings - change one or both?

« on: 21 November 2008, 19:15:22 »

Just to add... I chaged mine too. Only the bad one and it's running fine. If the other guy starts humming, check out and change, else... keep it .

Take a look at the shoks tower screws. They get loose and you risk you life. Mine were about to fall when I changed the bearing. Thankfully everything is ok now!

jack the car and not only shake but make the whell roll (run). Yu can notice a bad bearing this way too.

GLORY TO THE LORD!!!

Omega General Help / Re: [help needed] Electric radiator fan

« on: 22 November 2008, 19:37:20 »

Hi Andy and all... Well, i didn't do a thing today, as i tried without success to remove/clean the gear switch (damn it, it's tight under!) and started to rain...

However, the car is running ok again (i did nothing), and thankfully i found at www.abebooks.com some vauxhall carlton haynes' manual for a US$ 1,00... Now i just have to cope with that SOB of mine until the books (bought 2, one for the car toolbox, other for the bookcase) arrives...

 Time for a new 4ton floor jack and some tools (bought a 700g ball peen today... love big hammers, i'm into blacksmithing )

Ah... ok... I have a pdf copy of some manual, but it can't help much in any aspect. I also got a manual for my car... i like the pics, since that thing is written in russian or so.

My car has only one electric fan outside. Later models came with 2, as you said. Here the Model A (Carlton - cigarette brand??? ) was produced from 1992 to 1998. The caravan was built from 1993 to 1996. GM gives me headache sometimes... The very same car is made in many countries with different names etc, making a lot of confusion. I got relief when i learned the 4L30E trans is the same american thing that fits many models, thus making it a lot easier to fiz just in case...   Other stuff is like mining diamonds... lots of work and a little gem from time to time  

Back to the topic. Looks like the electric fan alone is not enough and the electric motor of the other runs faster than the usual idling at 800rpm. That's why a have a hot head... but doesn't explain the cary idling. I'll try cleaning the whole thing tomorrow as it's Sat and I bought a new can of that "stuff"...

Hi! Well, looks like the previous owner made some "tuning" then, cause my fan only runs with the engine movement. I think i understand what you said: there's low speed fan, that one driven by the belt, that also have and electrical motor, maybe? And the big fast one outside. That wont go with igntion off.

My gauge went to 110C, what made me concerned for a while, then back to 100C. When i turn engine off, did stuff and started it again, it was marking 110C, then 100C, then again 110C at jam, then 100C on the road.

Thx

Omega General Help / [help needed] Electric radiator fan

« on: 21 November 2008, 22:03:06 »

Hi all. I got the following sympton today. It's very hot today (about some 30ºC) and i got into a big traffic jam in Sao Paulo (one of Brazils biggest cities). Well, the engine got very hot and when the electrical fan started working, it was idling at higher speeds. What could this be?

I cleaned the idle regulator these day, but i was short of carb cleaner, so i decided not to open all the rail/air inlet stuff to clean.

Could be maybe due to some electrical issue involving the fan? Is normal for the fan do go off when you turn off the keys? I saw other cars that keep the fan running even when the car is off... i think its smarter even if it eats some battery, cause you don't leave too hot water around. but i just dont know what 'im talking, i'm no enginneer...

ideas anyone?

TIA!
---------------------------------------------------------------------------
another silly joke. here the word for "engineer" is "engenheiro", the same word used for a guy that is a "garapa seller" (a kind of hot dog/fish & chips street tent that sell sugarcane juice (garapa) -- i like it!). So when when we wnat to play on a friend we tell the other person the friend's father is an "engenheiro"; this usually get some "oh... which kind of engineer? civil, mechanical..." Answer: no, he just drives a sugarcane [press] engine... nevermind... stupid joke... just had to say it...

just for the sake of our personal archive: can you post pictures of this part, showing where it's mounted on the various models? A mechanic showed me today my PMS sensor where i saw nothing more than an oil ball...

TIA!

Omega General Help / Re: NEWBIE asking for HELP

« on: 19 November 2008, 14:54:37 »

Hi Gary.  My personal advice. Spend a lot of cash now, layback in peace tomorrow. Bad surprises you'll surely encounter:

- check those belt tension wheel. they break suddnely and leave at roadside. TIP: change all them at once, learn how to change a belt, have the wrench and a spare in your trunk. soon or later you'll need  :-/

- run (mean, go with care) to the mechanic and ask him to take off both front wheel hubs and check the bearings. There are some support screws too that may become loose, make noise and risk your life.

- check radiator lid if it's ok, else buy a new one. I used a cheaper ascona/monza, as the original omega costs 20x more (judge yourself what to do and ask an expert if in doubt)

- check fan relay (temperature) and fuse. If the fuse goes or the sensor fails, more roadside and lots of steam... :

- check (test) fuel pump and its relay. Don't wait until you stop at roadside to remember (i did it...). (applies to petrol. dont know diesel)

- change all filters, specially fuel (applies to petrol. dont know diesel)
(is there a valve to flush old diesel in your car? if so, use it at least once a month to clean water from fuel... diesel is awful somtimes)

- clean idle sensor, and air intake it gets clogged. seriously. car won't idle and will burn more gas (applies to petrol. dont know diesel)

- clean / check starter motor. it gets clogged, burn its brush,etc, and there you are at roadside again... do it now, not next year

- for lights: check every fuse and relays (sorry haven't the instructions, saying my generic knowledge), clean contacts. check for grounding... some stuff wont work if not well grounded, that is tight your screws well and dont forget hanging wires...   (i do sometimes)

- what's this blower fan? turbo stuff or else? Im ignorant on this... Well, always check eletric wiring if its and fuse.

sorry for being so ignorant. HTH in some  way  :-/

Omega General Help / Re: Auto gearbox selector lights come on.

« on: 19 November 2008, 14:29:08 »

don't tell anyone.. i was thinking this gearbox had some critter inside.. no clue about numbers, letters and not even thought that it is not that hard do fix... that is. not easy, but if you can read the instructions...

my car wasn't idling... i never knew before what a idle sensor did, what was, WHICH thing under the hood was it (i never knew there was such a thing... in carb you adjust 2 screws and you're done). I took take thing off, cleaned, then MAGIC! the car is no more crazy... and idles like a clock...

looks like the guys put these ugly names and myths around cars in order to keep you away from under the car... and buy a new one next year, after everything starts to melt and you don't have a clue from where to start (and your mechanic doesn't help either)...

Funny (or not): in portuguese the word for "tinker" is "mexer", it has the sound of "mesh" + "er" > The word for "mechanic" is "mecanico".
When you want to say a guy a "tinker of a mechanic", one who can't find a seed in a watermelon, we call them "mechanicos" (meshaneecos). The best tool for finding "mechanicos" here is a broken Omega... They will reveal themselves too soon!
