Reply to "Ceramic coating for coolant pipes??"

Larry,
Stainless steel isn't a very good conductor of heat, so I don't think ceramic coating really hurts heat dissipation very much. Now, if the tubes were aluminum . . .

I'd have to agree with David. I don't think it will make a measurable difference in coolant/engine temperature.

1. The coolant tubes do not serve to reduce coolant temperature. They merely transport the hot coolant to the heat exchanger (radiator is the exit point for heat in the coolant).

2. As David pointed out, stainless is a lousy conductor of heat, so probably no difference in coolant temps from passing through the tubes. I put stainless headers on my Mustang and find that an hour after shut down they're still too hot to work on the engine. On my Pantera with ceramic coated headers I can comfortably work on the engine around the headers about 20-30 minutes after shut down.
