Not exactly what I expected to read.
I thought this was going to be about transmission/engine oil/ power steering cooler issues. Most cars with an automatic or cvt use a cooler that is inside the radiator. Back in the day when I was an active mechanic in the 90s it was common to have transmission damage in a car that was over heated which used a radiator internal cooler vs an external cooler.
I dont really buy this. The power used to power the fan is way less than what is needed to overcome air resistance.
Having said that I know the gen 2 insight starts to retard timing and notice a lack of performance as the water temp passed 185. I had undo part of my gril block and tried water wetter. It made the difference so I can cover up againand get the savings plus make the cooling system work better.
