Hello
Problem: Temp fluctuates randomly (not every time) when in stand-still traffic on 30min+ journeys. Temp raises fairly fast to the H position, a warning sounds and the system corrects itself.
So about 4 months ago, when it first happened, Kmart bled my cooling system to ensure no air bubbles were present after my temp gauge
At the time, no leaks were detected and the car went without a problem through winter on short trips.
Today, on a hot day and a long trip, and only in stand-still traffic, the temp gauge slowly crept up randomly almost to the High position which I then received a High Temp warning and the system then corrected it and dropped back to the normal temp. Occuring randomly and not all the time, I am confused by the system decided to fluctuate.
Being a VZ V6 Calais, I know the thermostat and waterpumps are common problems and so too are the radiator caps. Kmart Auto recently determined the heater tap and hose is leaking, although the coolant levels are actually ABOVE the recommended levels. No liquid found on the road. I am getting them to fix it.
Can anyone with experience through so light as to whether the heater tap and heater hose is causing this problem as Kmart thinks it will only fix it at a 60% sucess rate.
I cannot confirm a blown head gasket, though this is my worst fear. The car was always stationary when the temp went to the H position. The car was driven very lightly (revs below 2500) when the temp was elevated at around mid-way on the temp gauge.
There is also the chance of the temp sensors failing and the cooling fans are working fine. In hope to cut costs, can anyone recommend how to go about testing what to rectify this problem?
Appreicate it!
