beast overheated,

[Ryoken]

had a bit of a worry yesterday, coming home from the shops, noticed temp gauge almost in the red, dunno how long it had been creeping up there, got home. now I know it was a hot day (24 degrees) but , really?.
lifted bonnet , cars running sweet as usual , thermo viscous fan spinning as normal ,

turned car off and left it ,
water level was ok. and oil level ok ( checked when cooled)
checked codes with scanner 1.41. came up with nothing ,
is there anything these engines are prone to doing when warm ,
or am I just worrying too much?

update...............

just to update you guys,
fired beasty up , sat there idled for 30 mins (while I was cleaning garden)

temp gauge read 1/2 went on motorway shortly after , got about a mile or 2 and the gauge started creeping up , right up nearly to the red, but not quite, pulled car over opened bonnet, NO fan on front of radiator
put heating on , full and hot , temp came down , limped car home , turned heating off, outside house, gauge increased, still no fan

either fan or sensor ,
I read codes again this morning , says nothing about a temp sensor failing
is there a way to test the front fan, now it spins freely, not seized,

Firstly, 24 isn't hot mate. I drag my 2.5 ton caravan in 35 degree temps and the needle barely moves even hauling up hills.

You got something going on and unless dealt with could be fatal for the engine.

Wish I had some insights for you but I don't I'm sorry. Hopefully the petrol engine gurus will be along soon

its hot for England
any one know if you can fire the fan up from a scanner/reader. as my fan has 3 wires on , so I don't think its as easy as plugging 12 to it

I concur with Trader4 it sure seems like a sticking thermostat.

[Ryoken]

thermostat is about 5 months old , im going to take it to garage and get them to test or check it seeing as they fitted it

took beasty in on Monday morning ,still not got it back yet.
plus still no closer knowing what it is
he was running tests yesterday, but didn't call to tell me what outcome was.
but he's not ruling out a bhg
and if it IS a bhg, then its bye bye x5

so even though I don't know what's going on im starting to look for a new car..

BMW X5 4.8 5dr

what you guys think of this?

[ants_oz]

A blow head gasket does not automatically mean the end of the engine.

[Kristophe]

you'd have coolant loss if it was a BHG

[Ryoken]

im still waiting on garage,
will update when I get info

A stuck-closed Tstat. failed fan clutch, or blockage in cooling system. That's it.
