Re: 2000 JGC V-8 overheating/ occasionally only !!
 

We actually sometimes have to block the air flow through the rad or the
engine won't heat up at all up here in The Great White North. You see
tons of vehicle with cardboard over the rad or grill in the winter.

I can see where an 'air' blocked rad will up the temperature the fan
clutch sees and where a 'core' blocked rad will lower the temp the fan
clutch 'should' see...

All these anti pollution gizmos are based on an average, they don't work
well in extremes. The fan clutch, the automatic choke, etc....

Holy Jeezus.

Do me a favor and either explain to me how a fan clutch will work
properly with a plugged radiator (intermittently or not) and sort this
out:

"The weakness of the bimetal coiled clutch fan concept is that it
reacts to the tempature of the air coming through radiator core not
coolant so on a cool day it is possible to have it run hot and not have
fan engage because the air is still not that hot because it

If your cooling fins are all smashed in or full of dirt, so that air can't
get through your radiator, then your fan clutch won't get hot and won't
engage. On the other hand, if the radiator is plugged internally so that
coolant can't get through it, then there won't be enough heat passing
through the radiator to warm up the fan clutch. Simple, elementary physics.
What comes out, is equal to or less than what goes in. If you pour water in
there, you can overheat your engine with a radiator full of ice.

Please explain how a good fan clutch will operate properly with a
clogged (intermittently or not) radiator.
