Part 1: So i put new Denso O2 Sensors in and fuel mileage hasn't changed yet for the better
so very quick history
Original 2001 engine 220k kms getting around 16lph around town and as low as 13-12 on the highway
I accidently blew my engine and got an alleged lower km newer one 2003 with maybe 120k kms it started at about 18lph and i think on my trip to tasmania i could only get 15-16lph
should i reset the BCM? and if so how.
Part 2: My hydrolic thermo fan is on its way out is this a serviceable part or do i have to source a new/ 2nd hand one
