Thing is, if the engine is actually running that cool, then the oil won't cook off the nasties and you'll have bigger problems down the line.

The only reason I covered my rad was to try to put some heat into it. I had 2 temp gauges. 1 either side of the thermostat, so I could "see" it functioning. My engine would produce heat, plenty out of the heater ducts. But radiator had plenty of time to cool between cycles.

This was after I did the floor covering, fixed the blend door seal. Patched the swiss cheese squirrel cage cover (underside of this cover in the engine compartment was rotted out and not visible until I pulled it off.)
