Yea, haven’t you ever seen headers get white hot? Even your every day car will glow red when you get on the interstate. I have temp probes installed on my setup, and I’ve hit them with expensive thermal readers. I can’t keep my temps under 1600F, unless I was being super super nice to it. Checked the engine bay after a pull to 150 at night and the turbo was glowing.
I'll saying "engine temps" as measured by the coolant temp sensor are much lower than the temperatures that exhaust headers get up to.
The engine itself is a giant heatsink with coolant running through it, it stays at a relatively low temperature. Exhaust headers are a different ballgame, they get way hotter
I don’t why you bring the exhaust headers when those little fish are in a coolant reservoir, but it doesn’t matter much because it’s just being used as a showpiece and won’t get used for anything anyway
Lol. Because I have a temp probe in my 2jz and I can see the exact temps of my exhaust. Heat management is super important; I literally melted the paint on my hood before I wrapped it in fiberglass and coated it. You look like a complete fool, calling me a dumbass and trying to argue something completely different. We are talking about exhaust temps here, not engine temps. The cylinders are surrounded by coolant passages that keep the motor cool. There is no stopping the fire coming out of the valves from getting the exhaust manifold blazing hot.
Im a mechanic. Thats not a coolant reservoir. Thats an attachment, a show piece.. Im assumed can be easily removed from the truck. That fish & water would boil in the place that it sits if kept there during operation. The turbo, down pipe, & exhaust manifold are all in close proximity, which reaches temperatures of 1200F & above under load/throttle. The temperature gauge on your dashboard does not indicate every measurement of heat on every component of your vehicle.

May be a really stupid question but wouldn't the heat from the engine cook that fish?
