I will have to second Dan Lessers comments. Back in the early 90's Ford motor Co.as now, was making ambulance chassis'. The differnce back then was that they were using 460 gasoline engines in most as the diesels were not nearly at the level they are today.
When a 460 was stuffed into an econline F250 or 350 chassis, add a pair 250 amp alternators and hugely oversized A/C compressor, and drive the hell out of it, or have it idle for long periods of time, a HUGE amount of heat builds up.
The stock rubber hoses would fail sometimes catastrophically sometimes a small leak. The small leaks, hitting an exhaust manifold caused dozens of fires. Yes, antifreeze does burn. As a volunteer paramedic, I watched our services rig burn half to the ground as a result. Ford replaced the rig, and retro added silicone hoses to the vehicles to prevent fires and leaks. The problem was that you could continue to sell antifreeze from time to time even though there was no leak.
In the turbo community I know that there are folks who use the rubber hose and put a silicone liner over the hose for heat protection.
