It does effects heat transfer.

Take IC and flush it with some degreaser and rinse completely with water. Just remove the sensors and cap off all the opening except the inlet. Mix a 75 concentrate of water adn a good degreaser like simple green. Pour in fill up 1/2 way and swish around. Fill it up 100% and let it stand for a bit. Repeat the swish then rinse. get all major water out of it. Doesn't ahve to be super dry when it goes back on, a little water vapor in the motor won't hurt and thing.

good luck
