The "parts cannon". Great line I just learned. Easy to exclude the heater core acting like second radiator: just make sure the heater hoses aren't full temp. Heater off. Engine takes to r long to reach closed loop. I suspect you can IR temp the upper hose on the radiator it should not be hot until reaching operating temp and thermostat opens

Yes, I agree 100% with that statement. My E46 water pump failed at 150K and I indeed fired the "parts cannon" at it. Every part short of the heater core and heater hoses. $1700 at the dealer for everything and I installed it myself. Been strong now for another 51K with no issues. I love my X5, I'm just trying to balance throwing too much money at a 14 year old car. Everything has 150K on it now.

I would maybe wait for the water pump to fail as the trigger for the parts cannon on that overhaul. I'm right at the point is about time. It's so easy to do hoses with quick release I think I may do the refurb in stages. Wife's car is about 10,000 miles behind me so that should space us a year apart.

I took the drive this morning to validate the temps on the highway. Sure enough, dropped to 67C. As mentioned above the car sitting in traffic would hold at 88C so it looks like it is certainly a soft fail thermostat. I picked up a new thermostat and housing from the dealer and removed the fan and shroud and am just waiting on the engine to cool a little before dumping the coolant to replace it.

All done and solved. About 30 minutes start to finish to replace the thermostat and housing. I spent more time test driving it after the job was complete. Looks like it holds right around 87C-93C all the time, on highway or in traffic.

Just for an FYI, the needle high noon position is buffered from 75C to 115C. 40C variance and you will never see any change. LMAO, BMW.
I changed this buffer on my E46 to be 90C-100C with the hex editor inside PA Soft 1.4. I really should have a look at the hex on the E53 and see if we can get the same results.

Absolutely!! I would be all-in for that info!! I don't have PA Soft yet, but I would invest in it if I could get all my temp gauges to read closer to real World values... I have an issue with my newest addition to the family... Becky, as we have begun to call her, will not heat the cabin, despite having hot inlet heater core hoses... The return is luke warm, indicating a blockage on the return side... Has anyone experienced this one? Anyone replaced the heater core yet? I have not pulled things apart yet... I saw this post and figured I'd add instead of making a new one... Cheers all!!!
