Hi 
 
	 
 
	My 2006 350z has recently started blowing cold air whilst idle and even when moving it wasn’t as hot as it used to be.  
	 
 
	Today at the end of a 30 minute drive the fans came on and didn’t go off, the stock temp gauge moved to the middle but my aftermarket temp gauge was at c85 and normally fans don’t kick in until 95.
 
	 
 
	Other things which maybe related;
 
	 
 
	Squeal from the engine bay (sounds like belts)
 
	 
 
	Aftermarket oil temperature gauge has been bouncing but when settled reads normal
 
	 
 
	6/7 months ago it has a new radiator, cap, hoses and thermostat 
 
	 
 
	Any help would be appreciated 
 
	 
 
	Kev
