Well, it turns out that when taking the car out on the highway at more than 100km/h, now with the heat the temperature is rising little by little, it rose to 97°C, I stopped accelerating and the temperature dropped again. If I go 90-100 km/h the car runs fine. It does not pick up pressure or raise the level of coolant, so it seems that the cylinder heads are fine, the water pump I put new 3 years ago and about 25000kms. The radiator has been cleaned and the thermostat new. Could it be one of the cooling sensors? Do water pumps fail? Let's see what you think

I have always found the 3.2, and 3.0 before, always is a hot engine and in Summer weather can often get up close to being at the 95+ degree mark.

Never had any problem with that and always found the tempreture drops just as you think you are going to blow!

Some perspective. What's the outside temperature when you're doing this?

If you put an pfl auto radiator in,using the in built cooler,will run about 5' cooler,  3.2 runs slightly warmer than 3.0L..

Blow the radiator fins out,from the back forward, if still warm change the thermostat, still runs warm, might be a blockage, check rad gets warm all over.

I suppose if you’re going to flush do the heater at the same time👍

Well, the truth is that the needle was in the middle although it normally works in the lower line, if it wasn't for the obd that I saw 97℃ in theory it would be within normal, but I don't remember how it went in these conditions before riding the 3.2

More than 30℃, almost 35℃ but I would say that it starts to happen after 30℃, in winter it has gone well. Maybe the A/C increases the problem

Interesting, I guess it's for the oil, where does that radiator go? I have an omega 3.0 auto restyling located

I'm sorry but I don't understand, what do you mean? Heater matrix?

Well, I've already seen what you're saying on google, I've seen a radiator with some connections that will go to another auxiliary radiator, but I can't even see it in the GM part. Do all omega 3.0 automatic pfl carry it? How curious that they removed it

               Just saying if your flushing the system do the heater radiator as well

Ah, ok, the matrix is new

[Raeturbo]

I meant you’re ahh good no need if it’s new then👍

My previous post believed as you live in Spain, and in certain parts have had record breaking temperatures recently, you had experienced at least 30 degrees+.  My answer accounted for that, and certainly when I have run my 3+ litre Omega’s in outside temperatures of the same level at speed along motorways for long periods, my gauge also ran to over 95+ degrees.

So, personally, I would not worry about yours running at high temperatures.  As I said, our big engined Omega’s are always running hot, especially in hot weather, which you feel when you step out of the drivers door and the heat roasts your legs!

Agreed with all above.

My 3.2 normal sits at 92.5 to 95.0 on most days.When summer arrives and outside temp gets up into high 20,s to 30 it often goes up to 97.5 when pressing on especially up hills.

Its perfectly normal and given the temp gauges are notorious for being inaccurate I would not be at all concerned.

If it goes above 100 or into the red then worry but otherwise dont concern yourself
