Yes, you can shorten a fan blade<\/a> in most engines, but it’s a precision job. Every blade has to come out the same length, the edges need to be smooth, and the assembly has to be balanced before it goes back on the water pump<\/a>. People usually trim for clearance reasons, like a new shroud<\/a> or radiator<\/a> that no longer fits the stock fan, or to drop tip speed for less noise and drag. The biggest risks are vibration, water pump damage, and weaker cooling, so the work should be done carefully or skipped entirely.<\/p>\n\n\n\n
