I'm ordering a new tank, but I have a question, is there a way to check the thermostat?
Is new too, but I don't want to drain the system to replace the tank, and then figure I need a new thermostat too.

Another question, when replacing the tank, should I order the transmission thermostat too?
Its also 3 months old.

Thanks !!

Depends on where you got it and where it was manufactured. If it's URO, it's usually junk and that's why it didn't last, Buy the parts from manufacturers that manufactured the original part. Doesn't have to have a Roundel on it as long as it was manufactured by the OEM. The crap made in China doesn't last. It's cheap for a reason.

Thank you all!

It was both, the level sensor (that was old)
And the thermostat that was new and failed in less than 3 months
I replaced them, and all seems back to normal !

Now just need to fix the programming of the idiot temp dial.

How do I do that?
Seems to be working fine.

"fine" as in normal is basically a 3 position dummy dial. its either cold normal or hot. Hes referring to re-programming it so the hot and cold portions are more accurate. I want to do this also. https://xoutpost.com/1121333-post23.html

That's exactly the problem. It always seems to be working fine. There is about a 40° range sheet it points to noon

Oh, thank you both !!!

I'll Read that and try to do the programing !
That needs to be done for sure !

Glad you got things fixed. Thanks for following up. Tough when there is more than one failure to confuse the issue. :thumbup:

What was the brand of the new thermostat that failed? Could you tell exactly how it failed?

A couple of months ago, I posted that after a tune up, my mileage was worst, someone suggested me to unlock the hidden menu and check the temperature, so I did.
And the temperature was jumping, not too bad but between 90 and 104.
Anyway, I totally forgot about that.
Then:
It started with random "Low coolant level" warnings, that would come and go. (That was obviously the sensor)

But pretty soon after that I saw the temperature gauge go up (at around 1 o'clock) and then back down ant 12.

That's when i started this thread, and while I was trying to decide what to look at, I remember that someone had mentioned on my other thread, that, that variation was not right on the thermostat.
I'm not sure what the brand was, but had good Amazon reviews, the only noticeable difference was that the connector had a different orientation.

So I decided to get a new one from ebay (following a link that someone posted on this thread), and voila !!
