high temp in the exige

Drove the exige down south today. All good on the way down parked the car at the house then went back out 20 mins later and the temps of the car went up to 100c. Had new ali rad and fans not that long ago. Noticed some coolant has come out the ex tank.any ideas why this would be? Seems to be fine again.

Cheers

when was the last time you changed the cap?

Never!!! Would the cap make the temps go that high? You around tomorrow mate?

Could be a faulty temp sensor? I see 100 C in my car in traffic, even seen 106 once, fans kick in a bring it down every time and no probs to date related to temps

The thing is when I stopped I went back to normal I was seeing 100c when I was doing a good speed??

Air lock? Sensor for the gauge would give odd readngs if faulty too

Even though it looks like some coolant has come out the tank?

i was going to say air lock as well. Does the temp fluctuate? Does it make a difference when you use heater radio or any other electrics? Re. The cap, id order one up anyway. Always good to replace every year or 2. 6 pound iirc

Hmmmm I should really listen to what I read... Sorry, any mayo in oil?

An air lock may fluctuate the level, as the temp changes and air expands pressurising the sytem possibly forcing water out the overflow or cap?

I'm told those rads are a pain to bleed!

Drove the car back to scotland to pick up the PUG temp was fine between 83 and 87 all the way. Checked the coolant when i got out the car way way down again. So No idea what is wrong with it. Keep thinking HGF but NO sign of MAYO in the oil cap.

HGF doesn't always give you mayo.

Airlock doesn't always have to be HGF either.

Bleed the system, see where you stand.

Can a air lock just appear Shug? The new Rad was done about 6 months ago?

No, not really - there is always a cause. It just might not be HGF. Might be a pinhole somewhere, or a leak that has sucked some air in as it cools. I suppose technically, it should always push out under pressure, but there may be situations where a leak would suck some air in?

Coolant system isn't a speciality of mine

but that's as I understand it.

im no expert either and i dont want to keep banging on about this, but if the cap is knackered, is it possible that this is allowing the intake of air?
