I am not trying to stir up what seem to be heated opinions (pardon the pun), but I have always worried about the safety of flammable refrigerants in a diesel vehicle. There probably isn't enough refrigerant in the system to worry about, but I always wondered if a catastrophic leak would create a runaway engine scenario. I have heard of caterpillars hitting propane lines which fed the engine too much fuel, thus blowing the engine. Anybody think this would be a valid worry on our vehicles?
