I just watched your video on overheating. I have a 07 nissan murano with 270,000 miles awd automatic it is overheating I've replaced thermostat radiator is new coolant full no headgasket leak. It overheats while driving only I can let it idle in my drive way and it is at norm temp fans work. While driving I have to turn my heater on full blast to keep it from getting to hot. Any suggestions?
Definitely make sure there is no air in the system. Usually only driving is more commonly a restriction... heater core possible since the radiator is new
Bypass hose collapsed internal blocking flow
Thanks for reporting back with the fix!
Try jacking up the front end, open the heater valve and burping the system again if it wasn't done correctly the first time.
It was bad bypass hose
You might just need a new radiator they will corrode internally and not dissipate
Wrong. Like I stated in my question radiator was new. It was bad bypass hose
