I know theres alot of topics on this matter but i need real answers from a holden tech or similar out there please....
Ive got a vn 90 model thats been looked after from day one since rolled out factory and recently to improve fuel economy as i had replaced everything and had injectors properly serviced etc I was told to get my coolant temp sensor replaced as it was the orignal one & couldnt hurt to replace.Now ive noticed the temp will get around half way which it never really has done before and the thermo fan kicks in, It's summer now and there is plenty hot days then is this normal especially when stop start driving ??
My thermostat is ok had replaced in last year or so and top hose is bloody hot when you touch it,The one thing I was thinking of doing is replacing the coolant as it's been diluted a bit from after i topped it up with just distiled water from cracked hose recently so the boiling level would be higher now i would presume.I was thinking of replacing bottom radiator hose casue it looks old and flushing the engine and radiator with the garden hose.
The water pump was replaced in less than a year and isnt making any noises.
With me having the coolant temp sensor replaced could my mechanic have put in a higher degree sesnor? is this ok ? could have original sensor been stuffed and causing bad fuel economy as now car doesnt have petrol smell and economy is better.
Is it ok for the car to run half way every now and then aslong as the thermo fan kicks in? in winter seems not to got that high.
Sorry for all the questions but Im worried , the cars treated like a baby & i look after it oil changes etc, its just coming up to 190,000 km's.
Thank you in advance for your help ...
