Coolant Fan Problems

[D2BBA]

You might find that the fans come on after you switch the engine off because the water stops moving through tha rad which makes it get hotter after you turn the engine off as the sender is almost in the engine block.

Will have a look at this, but the temp climbed to 105o at one point before I panicked and hit the AC button.  I could hear the coolant starting to bubble.  I just dont want to let it climb and climb hoping it will activate.

Think i\'ll fit the new expansion tank, an alu AST and then look at a fan overide swicth just to be sure!  

Does anyone have faith in the std temp gauge?  It never seems to rise much past the half way mark.
