not a good idea.
I asked this about a carbed v8 that stayed cold (I wanted to make it warmer faster)

the reason by the ase mechanic:
the radiator rids of stuff through radiation, including some of the coils energy.

if its low volt, you make the engine a pig through ionization.
alot of engines have plastic over the top if one hasn't noticed, it helps the radiator stay away from intake.
alot of four cylinders, they are sensitive to this very physic. even my 23 year old has plastic all across the front of the engine, inline fours have the same. bigger engines pretend to own themself, its hilarious...(name a v8 gas with 200k on it)...
you can experiment, and dig out the sludge from the oil pan as a result, that is the friendliest outcome. I have gone as far as cold air intake for a carb, and suffer the long time waiting to warm up...just for the clean I know is happening. fire in fire out, fire once good and strong, no recycle. Even the alternator gets a flow, easy does it, blue sparks instead of yellow for the wires ...
