I discovered that the thermostat in this car is quite buried and I couldn't access it in the time I had.

Do OBDII monitor readings match with the needle? I plugged mine in and a reading of 73°C had the needle in the center.

Thanks, Paul- that is definitely worth looking into. When I was doing the initial bleed (funnel in the reservoir), I had my OBDII monitor plugged in and the coolant temperature got to 110°C, so the thermostat was open. The biggest "burp" happened when it was that hot. Is it possible that t...

Ya, that's where I got lost... I think the real issue is that the thermostat opens at over 100, and from my experience, the coolant never gets that hot during a normal drive.. Thanks. So I'll fill the block through that opening and bleed through the overflow. I wish this radiator had a cap- my Honda...

I recently flushed the coolant in my neighbor's 2015 XC60, and we've been watching it over the past few days to add more coolant as needed. We have noticed a very weird issue; if the engine has been off for a few hours and is cold, the temperature gauge rises to the middle within a few seconds of st...
