Well, my lack of confidence was well placed: no car this weekend. They've replaced the thermostat and temperature sensor but have introduced an air bubble in the system that's got to be fixed.

Sigh...

Well, on the bright side they realized a problem with the coolant before handing the car back to you. A 991 GT3 friend of mine had the dealer replace the thermostat and completely muck up the coolant refill. Only found out at the next track event where all the warning lights lit up like a Christmas tree.

Hang in there!

Good point: better to find and fix a problem now. I asked my SA if he can get someone to work tomorrow to finish up the work. Crossing my fingers.

I really hope someone didn't come in on possibly their only day off for bleed the coolant.

No. Hopefully it'll be done this morning.

Woohoo!



(On average, the cars in the garage get pretty good gas milage!)

Here's what was done to fix the car:







I don't fully understand the issue about the temp sensor opening at 211 degrees and how that related to no coolant getting to the radiator. Can someone explain that?

Very glad to have the car back! Hopefully there won't be any more problems any time soon.

Congrats on the safe return. Glad to see they also set your tire pressures in order to reduce greenhouse emissions.

Happy to see you get the car back.

Those bikes on the rack look like they're right above the car! I'd never be able to sleep with that setup in the garage.

Ha! Yeah, I noticed that too. I actually think it's a pretty good idea since unless you actually care about your car and driving, you've probably got your tires under inflated. And if you're round-glasses-wearing, Berkeley-living, bearded 40-something driving in the far left lane at 10 miles an hour under the speed limit in your Prius, then you've definitely got your tires under inflated!

I read somewhere that the tire pressure law will save 75M gallons of gas each year in California. That's incredible.

I was wondering if anyone would comment on that! It's a very solid rack, with very big hooks holding the bikes. We live on a very steep hill (the garage is actually on the top of the house), 300 yards from the most dangerous fault line in the Bay Area (the Hayward Fault). I suspect that an incident big enough to drop the bikes will also have the house sliding down the hill! Our earthquake kit is up the slope from the house....

All that said, I might switch the cars around or just put the i3 in the drive way. It's leased so it can sit outdoors.

Glad it worked out!

Not to parade myself,but I have called the thermostat in the first post of this thread.
The temperature sensor is responsible for turning the fans on when the car needs cool down. Like stuck in traffic at idle. From the technician's description,the temp sensor was indicating the DME that the car is overheating when in fact it was not. They use 2 or more temp sensors in modern cars these days,so the technician had a reference off a different sensor.

FergusH, why soooooo much coolant added? 3.79 L x 2 = 7.58 L. Is this 100% coolant or the 50:50% blend.

Not sure. Perhaps there were two cycles of draining and refilling?

Yes, I remember you called it! Seemed a likely problem.

Any thoughts on the "no flow of coolant radiator" comment? I don't understand that part.
