Chasing my tail here.
2017 xc90 t6.
Water pump was drawing too much with an internal issue causing a voltage issue. I replaced the water pump and thermostat while I was in there.
Issue is, car still gets hot 220, thermostats opens but getting poor circulation.
Upper radiator hose is 68 degrees as well as the lower hose. Cooling fans come on, but there is no heat being pulled through the radiator.
Took the upper and lower hose off and put a garden hose in it with out a lot of pressure and radiator flows fine. Tried hot water a can see with a thermal imager radiator is allowing water to floor throughout the core.
Water pump seems to be circulating. It’s been bled 10x.
Just curious, if the LIN Bus could be failing giving false readings on the scan tool.
Anyone have an issue like this?
Thanks
