Well firestone I'm beginning to regret trading in my little old very reliable Agila. Funny looking in the showroom at the new Vauxhalls an old guy said they are getting mucho to complex and he may be right. I've always been a motorcyclist and always dreamed of having a beemer now I have one ( second hand) I'm finding they are not the reliable pot of gold I once thought.

Indeed - I miss the simplicity of my old 53 plate Corsa 1.2 and wish I'd kept it now, so easy to take to bits and repair myself!

I'm tempted to try and find a decent example for sale locally even the late SXI+ models (56 seems to be the newest I can find) seem to be going for no more than £700 now.

Trouble is Susan I'm not sure if it's the rad, this motor had a turbo which is water cooled so the leaks could be in that the head, water pump etc etc. I'm taking it in tomorrow as I'm sure with it being just over one year old it'll have warranty left on it. One curious thing though the header tank cap just screws around it doesn't lock down tight but this might be normal ?
No it is not normal! It should screw down tight!
Radweld is not just for rads despite the name . It is most effective in small cracks in blocks and core plugs. In fact modern rads are not easy to plug and you already know its not leaking externally. Vauxhall used to put in a small brown block in the rad - looked like a dog turd - in every new built car to finish off the assembly job specifically for cracks and joints. Talking about 1960/70s!
Anyway not for warranty cars unless the dealer does it.

Don't regret it. They've added such features to extend oil life and engine life. Turbos put a lot of heat in the oil which will make it degrade alot faster and deposit a lot of carbon residue inside the engine if it's not cooled. Think of those french 1,6 liter diesel engines, they kill one turbo after another. One of the main problems on those engines is that the oil is not cooled.
But i agree, new cars have some complex electronics.

Well the dealer's tech spoke to me, he found a split hose under header tank. Funny I kept looking under the motor even had some news paper to check for drips and nothing, but there we go. Any of you guys know if I should ask them to change the oil in-case turbo running hot could have cooked it ( the oil that is) somewhat or am I being pedantic??
Thanks for all you comments anyways.

Glad it was just a split pipe and not something more serious! How long was it since it was last serviced? I'd just wait until the annual service is due but check the level and ask them to top it up if it needs it.

I Will borrow this topic.

In april i had car accident with my 1 month old corsa. Car was crashed on front right side. After repair i have second time now that coolant liquid was gone and splashed under hood. They found one crack so Will change damaged hose.
First time temperature went to 130'C, second time to 110'C.

Technican told me that on newer cars engine can't overheat so no damage was done.
Should i belive them.
Otherwise car was visibly repaired ok, no color difference, equal spacing on hood, bumper,... and driving normaly.

1stopel, the 130 - 110 deg.C coolant temperatures means the engine was overheating ...

Now the 1.4t engine with it's start/stop technology, may be a little more tolerant of a FEW temperature excursions. I believe I red somewhere it has some special self-lubricating seals and bushings in the engine (or it traps some oil), to minimize engine wear over the frequent start/stops.

This may be the reason the engine is still 'driving normally'. However I would also do the following quick things (if not done already), for peace of mind:

* Replace engine oil and oil filter. Do it Yesterday. The 110 - 130 deg.C temperature excursions may have very well degraded what oil was in the engine and continued operation may rapidly wear the engine out, even if now it 'feels' normal. Some soot or debris can have been generated also, resulting in partially clogged oil filter.
* If the crash was big enough to crack stuff on the inside of the engine compartment, do a wheel alignment check, just to be sure the chassis geometry was not affected.

Yes I think it's important to change oil and filter, I've told the tech at the garage I'd feel happier with having the oil changes but perhaps I should have said change the oil. Techs as I know (I was one once and worked in the fishing industry) some times cut corners because of time and pressure constraints. The biggy for me why would a hose split after 12k miles and just over a year old???

TheGeorge i Will told them to change oil and filter. They told me when ''new'' car is heating it limits to 2500 revvs and won't allow engine to overheat. I also saw on board computer that 'ESP'?? or aircon sistem is off and engine turn off warnings.
I told them 130 and 110'C is a lot to be without any damage. They said if anything goes wrong even if waranty expire they Will urge to opel and Will repeare any damage.
