Somebody once posted that heater kits were furnished with 195°F thermostats to improve heater performance. Is this true and has anybody used one?

Here is another, perhaps more succinct explanation: http://yarchive.net/car/engine_water_restrict.html Copied the text from that link: From: John De Armond Subject: Re: Cooling system fact or fiction Date: Thu, 23 Sep 1999 06:12:19 EDT Newsgroups: alt.autos.rod-n-custom,rec.autos.rod-n-custom...

Sorry Rick, your idea just doesn't hold water. Heat flows from hot to cold at a rate proportional to the difference in temperature. The hotter the coolant gets the slower the rate of heat transfer from the engine to the coolant. Slow down the flow of coolant, and you agravate the problem...

I've done testing with normal thermostat, high flow thermostat, and no thermostat. The operting temperature decreased with each step. Magzines have done the same tests. The thermodynamics agree with t. Yet, somehow, this myth will not die.

Remind tech support that they're not dealing with a small block chevy cooling system.

The thermostat in the multi is used to balance coolant flow between the radiator for cooling and recirculation back through the engine to prevent hot spots; I suggest keeping it. You really have nothing to gain by removing it.

Hopefully not too far off topic since I believe that objective is noise reduction... Has anyone tried the nylon engine driven fan?
