i think this may help pull more air throught the radiator
instead of the fan pulling air from engine bay, because of the big gap.

please double check and <b><u>make sure</b></u> that your engine/motor/fan is not moving around much.

i have soild motor mount!
this should help only at idle/moving slow
@ high speed this mod may reduce air flow
due to smaller fan shroud exit?

p

plz don't flame

 

Have you tested for temp changes?

 

uhh... no idea
i did this mod the same time i install the autometer water temp,
gutless thremostat.
it took sometime to warm up
i see a lil over 160 F after the car idle over 45 mins

 

Your theory is sound (reduced blade tip clearance inproves fan efficiency), but you're trying to fix a non-existant problem. If the fan was keeping the enigne cool before, doing this won't make it run any cooler.

And you should should put a proper thermostat back in so the cooling system works the way it's supposed to...

 

thanks for the input
i had planted to put the stock thermostat back b 4 winter.

 

you need to do it now...the car needs a PROPER and constant TEMP to operate at peak efficiency....a motor that is cold or too cool is almost as bad as one that is too hot....

 

i guess it'll be alright.
the weather is pretty hot down here
