Coolant Issue

[Jammon]

My 2021 Supra (~22K miles) just notified me that the coolant is low. I had the system checked and no leaky was found, but the shop add ~12oz to top system off. Has any else had a similar issue with coolant being low?

Hopefully they added HT12 and not generic coolant.

In regards to the error -- Everyone'll get it with enough heat and aggressive driving. I've had to top mine off a few times during track days (Distilled water)

Reminding me I should probably get a bottle so I've got one laying around

Please tell me you didn’t pay a shop to top off your coolant?

I got the same warning this past Sunday in a '21 Supra 2.0 (B48). Already topped it up with HT-12 and tho I didn't see any signs of leaks, the dealer is gonna check it next week.
Comforting to see it's not that uncommon.

Yeah, I had this on my '22 for the last 3 weeks. Turns out, the expansion tank was bone fucking dry (news to me), and I'm not losing coolant due to any leaks. I had hit a small log on the highway the day before this message popped up on my infotainment screen and just assumed it was damage from the hit. It wasn't, dealer didn't find any leaks, so they told me to keep an eye on it.

Glad to know this is a somewhat common issue.

Ever use Red Line Water Wetter?

Come to think of it, I've not checked my coolant level since like 2 yrs ago when I did the HPS bleeder.. well, that's only like 2k miles for me so no biggie, but I did order a bottle of HT-12. Thanks @Rensuhlo


By the time I get the bottle this weekend, I'm going to be putting away my Supra for the season.. but the car will be ready for next Spring.

Redline was a shit sponsor to me, so I tend to not use their products anymore.

But I have in past cars.
