  1. Cool me down to take another round

    I haven't yet but I thought about mixing a lower amount of the bmw ht-12 coolant with one of those or Summit Racing non-glycol coolant. Maybe I'll do that first for the low temp circuit to see if it helps lower IAT at all.

  2. Cool me down to take another round

    the only coolant you should be using on a track is water+water wetter.

  3. Blown Head Gasket ?? [HELP NEEDED]

    How low does your coolant temp drop after flooring it ? I don't have a catch can setup. Just running the factory pcv system right now. However, I do plan on doing pcv block off pins when I replace the head gasket since I'll be in there anyways. I can understand small amounts of smoke but it was...

  4. Bad direct injector?

    First off I want to say thank you for all you suggestions, I really appreciate it! I have done a smoke leak test but not sure if the smoke was able to get into the intake manifold as most of the smoke was leaving through the air filter. I want to give this another go but not need to figure out a...

  5. Bad direct injector?

    Have you ever smoke tested your intake side? That's another diagnostic that I don't recall in the thread's post history. Perhaps you have a significant leak somewhere, and the car is hunting, to the extent that it's tripping cylinder 1. Grasping at straws some more: How are your MAP sensors...

  6. Coolant issue

    I brought the wife's car in for service last week (same engine but in a real BMW) because the coolant was a smidgen low and the warranty is about to expire. They performed a pressure test and couldn't find any issues. The service writer (who I generally, mostly trust) said that it's very...

  7. Supra engine overheating

    Coolant target is 95c at operating temp and 107c at warm up. Control (when the alarm bells sound) is 130c. So you are close at 120c. Did you do the correct bleeding sequence for the high temp circuit? High temp circuit is with the engine running and low temp circuit is without the engine...

  8. Supra engine overheating

    Yep, if the coolant is low, you'll be shooting air bubbles through the system, and they could be super hot. If filling is needed be sure to use the right stuff and that it's mixed correctly as well (usually 50:50 with DI or RO water, i.e. from a grocery store, if it's not already pre-mixed)...

  9. 2 Port head cracked and burning coolant

    ...My Supra started smoking about a thousand miles after purchasing it. I could tell it was coolant by the smell and color. The warning for low coolant has come on twice in 9 months, and I’ve put maybe a half liter in both times. I took it back to the dealer and they claimed it was blow by, and...

  10. Mechanic flushed in wrong coolant type

    I really appreciate your guy's help. I did find some sources saying that cars which require the green coolant aren't reverse compatible with HT-12 though. The TIS doesn't really mention being able to mix them. By the way, Would anyone know how to flush them low temperature coolant loop for the...

  11. Correct coolant 2024 3 ltr GR

    Hi Guys. Can someone tell me the correct coolant to use in my 2024 ,3 litre MK 5. There seems to be some confusion at my dealership, it's not low but l do like some as a backup as my last 2019 Supra lost coolant and had to have the water pump replaced

  12. High oil temp WOT

    My personal supra with 600whp+, 28psi to redline, on track down the straight to 130mph+ This was also after five laps. Coolant temp is directly related with oil temps, which is why I asked him to log coolant as well. I bet there is air in the system and/or coolant is low.

  13. High oil temp WOT

    I had a reply in mind but it's related to coolant temps not oil temps. But I can't delete my reply so I guess I'll suggest filling the coolant and trying again. There's a bleed procedure to run as well. Not sure the Supra steps but in BMW land it's a couple of things turned on, then you set the...

  14. High oil temp WOT

    I am having issues with engine oil temps getting high after going WOT. During a single WOT pull <10 sec, temp goes from 232-252f. Driving around town, no issues with engine oil temp. Any ideas where to look? Only thing I notice is this coolant reservoir is a little low (which I plan to add...

  15. Cooling System Bleeding for MKV Supra

    Did you ever figure out the low temp side procedure?

  16. Coolant Drain and Fill Inquiry

    bummer. maybe i will just drain and flush with distilled water until it is clear. drain one last time and refill concentrated coolant to be about 50/50.

  17. Coolant Drain and Fill Inquiry

    I only got about half the coolant capacity of the low temp circuit out when I drained it at the radiator hose. I also got half the coolant capacity of the high temp circuit drained as well. A lot of the coolant remained in the radiators and heat exchangers.

  18. HVAC Issue, Driver Vent Temp feels off

    Hey guys, I got an interesting one. Essentially, the vents on the driver side (left of steering wheel and the vent in the middle closest to the steering wheel) aren't blowing the same temperature as the passenger side vents. At first, it was that the driver side vents weren't blowing as much...

  19. Brown Coolant

    I admit it is difficult for me to explain the cooling loss. My best theory is that the coolant level was already juuuuust above the trigger level for the coolant level sensor. Then, a small amount of natural-and-expected loss plus loss from bonding to the surface metals pushed it over the edge...

  20. Brown Coolant

    On the BMW S55, the top mount intercooler would leak and dump small amounts of coolant into the engine and cause a low coolant over time. I suspect the intake manifold integrated cooler in the B58 is also susceptible to a similar flaw. Other than a leaking cap or hose somewhere, there are only...
