So I am not at a total Loss on why my 400 is running 210 at idle. Start the car and it will just slowly get to about 210.
This is what has been done.
-All filler panels verified and good. Two rubber beside the radiator, Upper steel and lower fiberglass panel. - HD clutch with 19 inch Fan half inside factory shroud. -New Champion 4 Core Aluminum Radiator -160 thermostat with two 1/4 inch holes drilled. -New Flow Kooler Water pump -New Divider plated clearenced correctly to the pump. -Distilled water with Water Wetter
Timing is at the mark closest to the top of the timing cover. not sure what degree that is. Running a MSD complete setup timing is 36 total
So Im at a loss here...
A T-stat with holes drilled in it is not a t-stat. These engines run hot as per normal operating. A good 160 t-stat will be open most it's life. Putting holes it will not change that.
Stock rads are just fine so I can't comment on whether your new rad, pump etc are any better or worse. Where are you measuring the temp of the water? What kind of setup is it?
Stock parts when working correctly will keep the engine at correct temp. So have a lot of new parts and they may not be better than stock.
However, try putting on a large flex fan to see if that does the job. If all else fails go large with something.
You can get better coolant. Evans has a product that people have been raving about. Distilled won't do anything. In fact any coolant at 50% will cool better than pure water.
