What PR? As I read it, if you're cooling system fails you basically have
enough time to set it down then you're looking at a new engine.

So far, I've not read of any reported catastrophic coolant losses in
the Ford powered airplanes. There have been instances (I've read of
two in Bruce's newletter) in which the head gasket began leaking.
This resulted in pressure readings that were abnormal, and the pilots
in both instances noticed them.

The airplanes were flown back to their home fields and the head
gaskets were replaced. In one instance, the airplane was a fair
distance from the field. Inflight coolant temperatures did not change
much, it was the pressure when the engine was shut down that got the
pilot's attention.

When you think about it, where where might a catastrophic leak occur
and how? Could a hose burst? A hole develop in the radiator? Those
things normally don't just blow up and spew out everything, they leak
very slowly at first, and a thorough preflight should include looking
for signs of coolant leakage I'd think.

When you put together a water cooled auto conversion, you use premium
hoses and radiators, right? You don't install aged and hardened parts
do you? Well I'm not going to anyway.

I wasn't implying that a catastrophic coolant failure was a likely event,
but rather that this was an unlikely PR angle.
