Hi - I posted something on here ages ago about this but can't find it and its still not resolved. Problem is when I am sitting in traffic, the temp guage will obviously go up, but then suddenly has a tendancy to jump up to max, warning light on, before falling down to a sensible level again. Normaly I rush to put the heater on max to aid cooling and that works.
Coolant level is good, doesn't lose any - its been flushed ages ago and water pump done with cambelt. I had read somethiing about burping but perhaps I have an airlock and hadn't quite burped properly? Can someone explain the procedure please? (or other possible reasons for the temp guage jumping)
Other times, it doesn't do it. Just when sitting about in traffic occasionally.
Thanks

Odd, cooling system self bleeds so I would think any air would have worked it's way up to the coolant bottle by now? Might be worth repeatedly squeezing the large coolant pipes to and from the rad?but I'm not hopeful...
Seen mention of missing under tray causing slightly erratic gauge readings iirc, but not to this level.
No real experience of cooling issue personally. :-/

I think I'd be looking to change the temp sender & go from there. :-/ As Chris says, any air that might have been trapped will almost certainly have moved by now.

ok thanks - where abouts is the temp sender on a V6 roughly, then I know what I Am getting from VX :-)
I am positive its not the car running that temp, as it would steam out!! - and it returns to 'normal' as rapidly as it hits max. Maybe that the resistance in the temp sender is fubar I guess.
