That’s a good idea, can I just buy a Z4 coolant cap? It’ll be cheaper and faster to get than a new one from Toyota. That’s crazy because I’m also trying to mod my Supra, I have all my parts but don’t wanna add things until I figure it out.
No code was thrown which was stranger for it being empty and having the sensor on it since it’s the larger tank. Do you recommend any specific aftermarket cap? Thanks
My 2022 3.0 had white residue on/around my larger coolant. I checked my larger coolant tank and it was basically empty. The smaller tank was still filled to the max. The car has 25k. I see people replacing the coolant cap it seems to fix the issue. Are people replacing with another OEM cap or...
