How do you tighten your clutch fan. Im not using specific tools. I have a 1999 2.5L mfi 4cyl 5spd manual transmission. There was no nut for the fan just four bolts around it. I got it off fine but i am unsure how tight and how to tighten it. Ive never worked on a vehicle before and just pulled the thing off cause someone told me if i dont replace it my engine will blow. Please help i got this thing at over 300000 miles and just trying to keep it alive. Ive got bills to pay/ need to get to work.
