Hello every one.

Right here in Saudi arabia, Omega goes under Opel's branding. apparently, GM adopted alot of Vaxhull's development. You see Opel vectra, Opel Omega, Opel astra etc.

the GM dealer here is pritty bad specially with the Opel section. once you come in with your car, its about 500 US$ average. most of the time, nothing solved. Spare parts are high and basically the car is considered a curse if you own it, Specially that sometimes the weather reaches 54C over here.

sorry for teh long introduction. right now, i know an Omega owner friend of mine that got him self another car and is willing to sell his Omega. the car is a 2001 Opel Omega 3.0 V6 and he offered it to me really cheap. Then he warned me that the car has been having overheating problems since it passed its warranty period and some times, the heat meter tops red line. I would love to have this car if i could find a solution for the over heating issue. otherwise, i'm a student at college and its not really worth it.

before i posted here, i've searched and read 2 posts about the same issue but for different engines. the post that mentioned the eprson who locked his radio   and the other that pointed out the fuse location (neat picture it helps!)

what i need to ask right now is:- " what am i looking for? what am i checking? is there a list of things i should look for? priority? "

and thanks. i really love the way you people have provided information to owners about this issue. and it assured me that i'm in the right place!

Welcome to the site,  first of all it's worth checking to see if the fans are kicking in.  If not then it's check the fuses etc...  has the coolant ever been changed to your knowledge?  Could be simply old coolant! It may need flushing and replenishing. Does it lose any coolant?  if so it may have been topped up with just water.  

Does it actually go into the red sector on the guage, i.e. set the red warning light to on?  Or, just high...   they have a tendancy to read high anyway, just to panic you

I'll assume that it's an automatic,  there could also be a heat transfer from the auto box cooler which is a part of the main radiator.

Another small point, could the radiator fins / matrix be blocked with sand and restricting the flow of air? :-/

Maybe worth checking these basic things first..

Not much to go wrong - if the fans don't come on just above midpoint on gauge, you have a rad switch/fuse/fan/wiring issue.  If they do come on, you have either a coolant flow issue or ineffective rad.

All assuming engine is in good condition, and running right.

Thx for the reply guys.

so, if the engine is fine and every thing else is fine, would you sayit should run at normal temp even know its 50C outside?

I would imagine that the car was tested in hot weather.  Sadly, we can only dream of such temps here, so no first hand experience

Alright, i am now the official owner of teh car

kind of embarrassed to show the pictures of it since it needs loads of hand work ( inside cleaning, malfunctioning buttons, no alloy wheels, dried out tires etc )

as far as i've driven teh car, it doesnt seem to go above 95 what ever i'm doing.

but i cant really say anything about that til i get the A/C working ( can u believe its 48 C outside and no AC?!  :-? )

i'll post any updates i find.

any one has any idea about the A/C? its just blowing hot air like an oven. previous owner told me i need to change the battery to make that work properly and i'm like " huh?! " dont think that has to do with any thing related to the A/C does it?

[Albert1]

Two things to check - one is whether engine thermostat is functioning (if it's stuck closed, overheating would be likely).

Two, for the AC, can you detect a change in revs when you switch it on?  You should be able to, and that would imply most of the AC system is working, then I would advise getting the AC refrigerant level checked and topped up.  If the car has been neglected as you imply, it doesn't seem likely that anyone has been topping up the AC refrigerant gas.

When you say it's blowing hot air: hot because it's been heated or hot because it's hot outside? I imagine it's difficult to tell the difference but these cars have a heater bypass valve that is prone to failure, can result in unwanted hot air being blown into the cabin I think?

There are two aircon fans at the front that should kick in with AC on. The fan behind the main radiator is the engine cooling fan but the aircon fans help keep the engine cool as well.

On mine, The fuse below blows sometimes, resulting in the engine cooling fan and one of the aircon fans not working. That leaves one aircon fan, which only just managed to keep my coolant from boiling over even in the English summer!

i'm real sorry every one.

today i discovered the engine was damaged from the lower part meaning it bumped into something like a rock or so. and its leaking oil slowly when its standing but leaking too much when AC is on or u press the throttle paddle. talked to the cars' owner and he agreed to take it back

i really wanted this car bad. but damn right it costs too much to fix. front breaks were worn out resulting the the front left disk damaged and un-usable. the original breaks cost like 600 saudi riyals ( about 100 euro ) and each new disk costs about 1200 riyals ( about 200 euro ) meaning just to fix front breaks, i'd have to pay 3000 riyals ( about 500 euro )

compared for the deal i almost got on the car, this guy was selling it for 7000 riyals ( about 1100 euro ) and really, i'm not willing to pay the same amount to fix it

sorry every one, thanks for all tehhelp you provided. i've known more about cars since i came here and i will never forget what i learned. i wont be disappearing. i'll come visit every now and then.


cheers
