Temperature Rising On V6 !
Not really too sure what this is all about, but I have noticed from last week that the coolant temperature is beginning to rise higher than what it usually does. At either a standstill or in slow moving traffic, the gauge is rising to somewhere around the 110 degrees mark, which is definately higher than what I have ever seen it, and it does rise pretty quick when at a standstill. It also takes a while, when back on the move again, to bring the temperature back down, although the radiator fan is switching on and preventing it from going higher.
I'm not sure if this could be a faulty gauge/sensor (the warning light doesn't come on), a dodgy thermostat (which I replaced around 9000 miles ago), a leaking head gasket or anything else, although the coolant level is fine, and there is no scum or residue on either the oil filler cap or in the coolant header tank. The car drives spot on.
Any ideas anyone? I was thinking of maybe aquring one of the head/block leak testers and try it that way to confirm a leaking head gasket?
