What did you do to your Supra today?

[puzzled]

Meh.. I searched online all over the place on how to do a coolant drain and fill on my 2020. I don't have a vacuum fill device and don't feel like getting showered by coolant..twice. but I also don't feel like taking my car to the dealer just for this. Can the Supra survive gravity fill?

Not sure if there's a good way to drain the coolant other than disconnect the bottom hose from the radiator. I haven't personally messed with the cooling system before.

For bleeding, this should work:

Be warned, car will rev to 3.5k rpm during the process, might be worth getting an exhaust silencer, or just going to harbor freight and getting the vacuum bleed device

edit: Also worth noting the bleed procedure may be different for the low temp circuit. not sure off the top of my head. I'm sure there's instructions in that thread.

Changed my at 39,500km

1) ZF8 Transmission oil (Motul ATF)
2) Rear Diff oil (SAE 75W90)
3) Brake Oil (motul 5.1), Full flush
4) Cabin Filter
5) intake filter
6) Spark plugs

was a long time due since i bought the car at 38,000km and only changed the oil then, didnt know if the owner changed before, looking at the oil i doubt it.

They are recommending 30,000 km before changing the rear diff and transmission oil again, and 40,000 km before changing the brake oil again.

seems a little bit short? but meh, its cheap.

Kind of excited to be ready for my first track day ever in april.

Oil coolers work man. Will absolutely help with oil/coolant temps. My coolant temps at the track today were almost too low (ambient was about 70)

• Verus AOS
• Verus Oil Cooler

Are you still using these coolers?

The oil cooler yes. The other one isn't a cooler it's an air oil separator

I've posted on some of the work done to both the car and the diffuser itself to optimally run this thing but it's finally done.

I ended up not running the frame I had CNC'd to mount the diffuser. It made the setup way too heavy and my mounting points didn't allow enough adjustability. So after some consultation, I reinforced the center-top of the diffuser with really high tensile strength carbon fiber flat bars and the leading and trailing edge with aluminum angle bars. With everything weighed together, it came out to be 7.2 lbs. Overall, the process was a bit of a pain, but I'm glad it's done. Hopefully shakedown soon

Weather is back in the upper 50s/60s, so ethanol is back on the menu, boys.

So I heard BMW is recalling the Z4 for starter motor potential fire.. I wonder if our Supra's are going to burn up on its own too..

I do need a fire starter for my charcoal grill come spring..

B48 only. Doesn't apply to B58

Toyota.com/recall

Enter your VIN and find out. Starter to my knowledge is for the b48 motors.

 

[tracer bullet]

It is indeed only for those. Of course, some Supras do have B48's.

It was announced a few months back, dealers seem to finally have replacement parts now and can do the work. Theoretically you park outside until then. I think they replace the starter itself. What a PITA to do to a huge number of cars out there.

 

[Davo307]

Close friend of mine is a master tech at Toyota and said he's done the starter recall on a 2022 3.0 Supra which surprised me. I told him it was just the B48 and he said nope. But it was 2022 and earlier. Odd. Worth a call or check on your VIN maybe.

 

[tracer bullet]

Indeed you are right. Seems very few B58's, but there are some. '20-'22 for Supra would be worth checking on.

This is what he said. 20-22 only. I asked them what they changed and he shrugged lol. Is the starter a different part number from say a 21 vs a 24?
