sure that's not a relay you've pulled out?  The fuses have a coloured see through housing with the rating marked in white on top.

When the temp gauge hits 100 how many of the three fans were rotating and at what speed, slow or fast ?
Note: at that temp all three should be at fast, should have kicked in at 98 degrees.

Have a look at this post. http://www.omegaowners.com/forum/YaBB.pl?num=1215079466/22#22 there is a picture half way down of the fuse most likely to give a problem. You should be able to see if it has blown from above but pull it anyway and make sure it is intact. There will be a gap in the metal of the fuse when looking at it from the side (through the clear colured plastic) if it has blown. Probably blackening of the plastic too.

thanks for your clarification , i checked the fuses and they looked intact. what seems strange that i've driving the car for last few days with average temp of 90-95 no more spikes to over 100 !!!! cant explain this , whether its just the whether cooling down a bit i dunno..

guys i just want to thank you all for this great forum, i am very impressed with the quick responses, accurate problem solving, and the effort to explain in simple words for inexperienced guys like myself  
the water problem on the passenger side was actually caused by 2  blocked drains as you all suggested, and the illustration provided by x25xe was very helpful to locate the drains.
it is very amazing how your explanations guys reveals the garages stupidities , they were suggesting water coming from the radiator, heater matrix, air conditioning and they were trying to convince me changing these parts which was ganna cost me hundreds, but i am very fortunate to find this great forum..
The heating issue is not as bad as before i shall keep in eye for the next few days and see what happens, if the problem exacerbates i will come back for your invaluable advice again.

Glad you found the advice useful. There are a lot of really helpful and experienced folk on here.

I had a very similar 'overheating' problem myself which took a long time to trace. I hinted at it above but this is the link to my previous posting http://www.omegaowners.com/forum/YaBB.pl?num=1215079466/22#22. The bottom line is that as long as the coolant doesn't boil then it is probably nothing to worry about. It is very difficult to convince yourself of this fact if the gauge is going into the red and your sitting in traffic on the Motorway or alike.

back again , temp was sky high yesterday after half an hour drive, going into the red lines again and again, put the air con on and temp settled down, then i realised that i have been using the air con for the last few days when i thought the problem is sorted . i switched air con off and temp climbed up again , had a look at the earth lead on the battery, it felt very hot to touch, looked at the coolant and tried to open the coolant tank but i noticed there was a lot of pressure in there and water was ganna slash out everywhere if i continued, but surely i didnt....
now not sure where to start with this problem , shall i change the thermostat for a starter???

[rickyboy]

Pretty sure when the thermostat fails it sticks open meaning your temp would be low rather than high.  Need someone to confirm that though.

Edit - just read previous posts and Marks DTM suggested that the thermostat fails open.  If there is anyone to trust on this matter it be him!

[rickyboy]

Still don't believe you've checked the correct fuses.  The fuses you need to check are under the steering wheel not in the engine bay.  I'll have a look in my Haynes manual and see if I can find the exact fuses for you to check.

[v6coop]

Marks DTM mentioned recently that they fail open so this should not be the problem. Not a good idea to ever open the coolant cap when the engine is hot. It will boil as soon as you release the pressure and likely to spray all over you so don't go near it until it has cooled down.

A little surprised to hear the temperature goes down when you put the air con on. My theory about the negative connection would suggest that if you put it on it would get worse. However you did say it was hot. Was it too hot to touch? If so I would suggest checking it with a voltmeter as I suggested in the link above and report back your findings. Do you have a multimeter. If not you can buy them for under a tenner from Maplin amongst others. It needs to be tested with the engine running and when you are seeing the overheat, not when it is cold.

If the voltage is OK I can still only think that there is some problem with your fans switching on and off be it a sensor or relay or a blockage in the rad somewhere. How long have you had the car and has the oil cooler ever failed to your knowledge?

[omega2.2CDX]

 :-? well i followed what has been said before, the fuses next to the battery not the ones under the steering wheel, i am confused now, are those the ones i need to check!!!

[rickyboy]

Yes it's the ones under the steering wheel you should be checking.  F4 - according to Haynes.  The fuses should have a symbol under them anyway so look for the one that resembles a fan if not fuse 4.

[omega2.2CDX]

i check the fuses under the steering wheel , they all look intact however i also managed to lock my radio , and now in search for the code, going back to my car papers there is a key replacement code of four numbers is that the same for the radio, and there is also additional audio manual with title ncdc 2013, i will try both and see what happens...

You're not having a great time of it at the moment are you...

Radio code is on the car pass and should be marked Radio Code and then four numbers.  If there are two lots of four numbers split with a "/" it will be the last four you enter.

Still think you've got a split fuse I'd change the cooling fan fuse anyway just so you can be sure.

[omega2.2CDX]

none of the above numbers worked, cant find car pass , am screwed now
i will change the fuse as you recommended , but not sure how to get  the radio code???
