Agreed. Looks good, but what are your exact before and after numbers?!?
Vendor claims don't count for as much as lab experiments.
Just to think about - let's assume the hoses were perfect insulators, and none of the coolant heat escaped into the engine compartment. The heat has to go somewhere, and that's into the radiator. Whose airflow comes right back at the engine compartment!
And let's say the old hoses were made of metal and radiated like a banshee into the engine compartment. What percentage of heat would come from the sides of those metal tubes, compared to the HUGE metal mass of the engine and two HOT exhaust manifolds?
I myself have reinforced silicone hoses from when they were offered for the I6. I got them for peace of mind in 120 degree deserts where a burst hose would be much more than a temporary inconvenience. I'd have to wait until nightfall (and then some) to swap out for my spare rubber hoses. But as an engineer, I can't detect any temp difference by having them.
You have to be very careful with what's called "confirmation bias" when looking for justification for mods. As nice as they are, they may not do all the vendor claims they do.
DAMN. How did I get sucked into replying to a necropost!?!?!?!?!?!?!
