[DeTomaso] Ceramic coating coolant pipes??

[Larry Finch]

All,

Was speaking recently with another owner who shared he had treated his stainless steel coolant pipes with inside/outside ceramic coating. 

We had been talking about the coolant pipes radiant heat that tends to warm the cabin. 

I initially thought this was a pretty good idea but with more thinking I am finding there are two sides to coating the pipes. 

On one side, the inside/outside coating will serve to reduce the outside temperature of the coolant pipes, just as occurs with ceramic coated exhaust headers. Those cooler pipes …should… result in a cooler cabin.

But then I realized the heat blocked from radiating off the coolant pipes is heat that remains in the coolant, unlike in an exhaust system where the heat has a point of exit. 

So in theory, coated coolant pipes will provide a cooler cabin at the expense of increasing the coolant temperature. 

Open to everyone’s thoughts and opinions on whether the increased coolant temperature has the potential to be a problem. 

For the sake of this discussion, let’s assume the cooling system is a fully functional, upgraded aftermarket system capable of 200° idling on a 105° summer day
 
TIA,
